COMPLETE SPECIFICATION STANDARD PATENT Name of Applicant: Actual Inventors Address for service is: Acres Gaming, Inc.

John F Acres, Alec Ginsburg and David Wiebenson WRAY ASSOCIATES Level 4, The Quadrant 1 William Street Perth, WA 6000 Attorney code: WR Invention Title: Method and Apparatus for Controlling the Cost of Playing an Electronic Gaming Device Details of Divisional Application No: 32346/99 Filed on 31 May 1999 The following statement is a full description of this invention, including the best method of performing it known to me:- 1/2 Field of the Invention The present invention relates to electronic gaming machines, also referred to herein as gaming devices, interconnected by a computer network and more particularly to a method of configuring such machines.

Description of the Related Art This specification describes aspects of prior art networked gaming device systems. However, neither such aspects of prior art networked gaming device systems nor the description contained herein of such aspects of prior art networked gaming device systems is to be taken as forming part of the common general knowledge solely by virtue of the inclusion herein of reference to and description of such aspects of prior art networked gaming device systems.

Casinos typically include electronic gaming machines (EGMs) such as slot machines and video poker machines. The slot machines usually includes three reels that each have a plurality of symbols printed thereon. After the player applies a wager to the machine, he or she starts play by triggering a switch that starts the reels spinning. Each reel stops at a random position and thereby presents three symbols one from each reel. Some combinations of symbols do not pay any jackpot. Others pay varying amounts according to predetermined combinations that appear in a pay table displayed on the machine.

Video poker machines include a video monitor upon which the images of cards appear, as if dealt by a dealer from a shuffled deck, in response to player inputs to the machine. The player wins jackpots dependent upon the amount wagered and in accordance with the cards that are dealt.

When a new EGM, whether a slot or poker machine, is made available for gaming, it must first be configured. A programmable read only memory (PROM) is installed in each new EGM. The PROM includes data that controls the behavior of the machine, and typically also includes data that establishes the 1/3payback percentage, such data being referred to herein as the paytable. The paytable defines the average percentage of wagers that is returned to the players in the form of jackpots over time. Gaming regulations in many jurisdictions require the paytable to be stored in the PROM. The PROM must consequently be changed if the casino desires to change the paytable. Some jurisdictions, however, permit the casino to change the paytable by setting options at each EGM. Such options are selected by using a key switch at each machine that places the machine into a configuration mode. When in this mode, the casino employee configures the machine for such things as the maximum jackpot that can be paid by the machine before a hand payment is required. The rate at which the jackpot meter increments may also be selected as well as special effects generated by the machine in response to a jackpot. And if the jurisdiction permits, the paytable may be changed when the machine is in the configuration mode. Otherwise, the only way to change the paytable is to replace the PROM with another containing a different paytable.

Poker machines, when placed in a configuration mode as described above, display information about the status of the various options on the video monitor that is used to display the cards and other information when the game is played.

On the poker machine, sound, background color, and card decoration, which may be configured to display the casino's logo, are examples of the parameters that can be changed when the machine is in the configuration mode. It is easier to configure the poker machine because the monitor displays the status of various options as well as lists of options, from which a parameter can be selected and implemented. Slot machines, on the other hand, do not have a monitor and are therefore difficult to configure because the only displays available to indicate status are four-digit alphanumeric readouts that are used to display the amounts on the credit meter or the jackpot meter. Configuring a slot machine as described above can take about twenty to thirty minutes of casino time. Installing machines in a new casino, which may number in the thousands, or changing the parameters on pre-existing machines, is consequently a very labor intensive process.

It is also a process that lends itself to implementing, either inadvertently or otherwise, the wrong parameters. Thus, a group of machines that are supposed to be configured identically may include one or more that vary from one another because of an incorrect input during the configuration process.

Some EGMs include a primary game and a secondary game. For example, the primary game may include a slot machine that periodically permits the player to play the secondary game before the next reel spin on the slot machine. Some secondary games award a prize after the player spins a wheel. The prize is indicated on a sector of the wheel, which stops at a random location after being spun. Because the secondary game must be configured in the same manner as the primary game, the same types of disadvantages are associated with secondary games.

In addition, some EGMs include a dedicated progressive in which a percentage of all wagers made on that machine goes into a separate pool that is awarded by the machine. The payback percentage for such a game must also be configured, either by the casino or via a paytable included in a PROM, and therefore presents similar problems.

It would be desirable for a casino operating a plurality of EGMs to be able to change the effective wager per unit time required of a player of the machines.

The wager per unit time, which is the cost to the player for playing the EGMs, is a function of the payback percentage and the game speed. The faster the game speed and the lower the payback percentage, the more money the casino retains, and vice versa. Increasing the wager per unit time increases casino revenues up to a point. If the casino simply selects a very low payback percentage (or a very fast game speed) on all of its machines, the players may feel that they get better returns elsewhere. It would, however, be desirable for the casino to be able to vary the wager per unit time in accordance with the demand on the casino floor. In other words, during evenings and into the early morning hours on weekends and especially on certain holidays there are greater numbers of players placing wagers than, on a Tuesday morning between 7:00 am and noon. It would therefore be desirable for the casino to set the cost to the player at a higher level during high demand periods and at a lower level, to attract players, during low demand periods.

It would be quite cumbersome to change payback percentage, either by switching the PROMs from machines, or by placing the machine in a configuration mode in jurisdictions that permit changing pay tables in response to casino configuration. Changing game speed by switching PROMs or by placing the machine in a configuration mode would be equally cumbersome. It would be impractical to make such changes in a large casino even weekly, much less daily.

In addition to varying the cost to the players, the wager per unit time, in response to periods of high and low demand in the casino, it would be desirable to change the player cost in response to the status of a particular player. The casino likes to track players to identify big players and to conduct direct mail marketing. Casino management therefore encourages players to sign up for, receive, and use a player tracking card, which the player inserts into a card reader associated with each EGM. The casino can therefore identify players based on previous or current rates of play and vary the wager per unit time for that player accordingly.

It might also be desirable to change the cost to the player depending upon their status as a person that the casino would like to encourage to play their games or as the companion of such a person or of a person known to wager large amounts. Changing player cost in response to player status by switching PROMs or reconfiguring the machines is not possible.

In addition to the foregoing it would be desirable to change the manner in which the player perceives the EGM. In other words, it would be desirable to change the sound effects and appearance of the machine in response to time, the rate at which the interconnected machines are played, or the status of a player.

SYSTEM OVERVIEW A system for operating a plurality of gaming devices is shown generally at 10 in Figure 1. The system, hereinafter described, monitors and reconfigures a plurality of gaming devices or machines 12-16 and 22-26. The system includes the following capabilities: remote reconfiguration, accounting data extraction, integrated player tracking, and cashless play. Remote configuration includes sending a reconfiguration command from a host computer to one or more of the gaming devices. The gaming devices, on receiving a reconfiguration command, will reconfigure its jackpot payout schedule in accordance with the reconfiguration command.

This reconfiguration, in the preferred embodiment, comprises activating a bonus payout schedule. This bonus payout schedule is in addition to the normal pay table of the gaming device. This bonus payout schedule provides for additional bonus payouts in addition to the payouts specified by the device's normal pay table. The difference between the two may be important for regulatory reasons.

For example, in the United States of America, the composition of the pay table is subject to regulation by the various state gaming commissions while the bonus payout schedule is not. The preferred embodiment currently activates only the bonus payout schedule responsive to the reconfiguration command, while not altering the payout table. The invention, however, is not limited to activating only the bonus payout schedule. Other embodiments, which would be subject to regulatory approval, could modify the device's payout table. The preferred embodiment, however, does not.

The system, implements a variety of bonusing events through this reconfiguration process. These bonusing events include: a multiple jackpot wherein the gaming device reconfigures its payout to be a multiple of its default payout schedule; a bonus jackpot wherein the gaming device reconfigures its payout schedule to payout an additional bonus amount when certain conditions are met; and a progressive jackpot wherein two or more gaming devices are combined in a progressive jackpot having a progressive jackpot payout schedule.

The system also provides for integrated player tracking and accounting data extraction. The system 10 provides for player tracking and accounting data extraction over the same network. The player tracking allows the casino to run certain promotional events. The integrated player tracking and accounting data extraction also allows the system to support cashless play wherein a credit is given to a player over the network.

The system 10 includes one or more floor controllers 18 and 28.

Each floor controller supports up to a predetermined maximum number of gaming devices. In the preferred embodiment of the system 10, each floor controller can support up to 1024 gaming devices. The preferred embodiment of the system 10 also supports up to eight floor controllers.

Thus, the system 10 can support up to 8192 separate gaming devices.

The system supports a multiplicity of various gaming devices. The gaming devices 12-16 and 22-26 shown in FIG. 1 are the type having a pull handle for initiating a game, slot machines. However, the invention is not limited to such gaming devices. The gaming devices shown in FIG. 1 can also be gaming tables or push button operated machines as well, e.g, video poker. As will be described hereinafter, the system supports any gaming device providing traditional discrete connections, coins-in, coins-out, etc., as well as those having serial interfaces, as described below.

The floor controllers 18 and 28 are, in the preferred embodiment of the system 10, IBM-compatible personal computers. Each floor controller is responsible for monitoring the activity level of the corresponding gaming devices connected thereto and issuing commands to the associated gaming devices to reconfigure their payout schedules during certain bonusing events. The floor controllers issue status requests to each of the individual gaming devices to determine the activity level of each. In the event the floor controller detects any activity, the floor controller communicates that activity to a file server 32, which is connected to the floor controllers via a high speed network 38 connected therebetween.

In the preferred embodiment of the system 10, the file server 32 includes a high performance personal computer or work station having a large hard disk capacity in order to store the gaming device activity therein.

In the preferred embodiment of the system 10, the high speed network 38 is a ten megabyte ethernet network. The system 10 also includes commercially available network software to support the industry-standard ethernet network 38. An example of such network software is Novell network software sold by Novell of Provo, Utah. The file server 32 also includes a database program by which reports can be generated using the data stored on the file server. Such reports include, e.g. area, model, denomination and summary reports. The database software also allows a user to generate custom reports. The database software is based on the industry-standard Paradox database language.

The system 10 also includes a pit terminal 34 which is also connected to the ethernet network 38. The pit terminal 34 is also a standard personal computer, in the preferred embodiment, and can be used to monitor the gaming device activity in the pit. This terminal 34 can ial5( be used as a security moitoring, device to dletect anly unatiicipated. events I ike fills or payouts.

The systemi 10 further include.- any nmnrber of fil and jackpot processig terminals 3.

The above-described system 10 is but one embodiment of a system in which the method according to the invention has application. The system tasks can be allocated in a variety of ways amongst the system computers including floor controllers 18 and 28, file server 32, pit terminal 34 and fill and jackpot terminals 36. In some cases, the pit terminal 34 and fill and jackpot terminals 36 can even be eliminated and their tasks allocated to the floor controller or file server. In fact, because the file server 32 is essentially a virtual hard disk for the floor controllers 18 and 32, the floor controllers and the file server can be considered a single host computer for the system B. DATA COMMUNICATION NODE 1. OVERVIEW In order to communicate with the floor controller, each gaming device includes therein an electronic module 40, as shown in FIG. 2. This module 40 can be inserted into a variety of pre-existing gaming devices. The module allows the host computer to uniquely identify the gaming device on the network, including the device type. The module 40 includes two main subcomponents: a data communication node 42 and a player tracking module 44. The data communication node 42 keeps track of the coinsin, coins-out, coins to drop, games played, jackpot occurrences and other related functions of the associated gaming device. The player tracking module 44 keeps track of the player that is playing the associated gaming device. Together, the data communication node 42 and the player tracking module 44 allow the floor controller connected to the associated gaming device to monitor and control the activity of the gaming device. The system hereinafter described in detail includes the following capabilities: slot accounting, player tracking, bonus jackpots and cashless play.

The light imask 138 is :t0 associated wvith time arr-ay of pliotodiodes 134 aind Ii s a pluraility or openings therein, each opening corresponding to an individual photodiode in the array 134. Similarly, light mask 140 is associated with the array of photodetectors 136 and also has one opening for each of the photodetectors. The light mask 138 is mounted on the printed circuit board 130 beneath the array ofphotodiodes 134 along the opening in the printed circuit board 130. The light mask 138 is aligned with the photod iodes 134 so that the openings in the light mask 138 are directly beneath a corresponding photodiode in the array. The light mask 138 minimizes the amount of light emitted by a photodiode that can be o1 detected by a photodetector other than the corresponding photodetector.

The light mask 140 is mounted on top of the photodetector array 136 so that the openings therein align with the individual photodetectors. The light mask 140 further eliminates extraneous light from the photodiodes as well as extraneous ambient light.

Also mounted on the printed circuit board 130 are a plurality of light-emitting diodes 142, as shown in FIG. 7C in broken line. The lightemitting diodes are mounted on a side of the printed circuit board opposite the side on which the photodiodes and photodetectors are mounted on. The light-emitting diodes 142 are mounted around the perimeter of the opening in the printed circuit board 130 and are received S* in a recessed portion 144of the bezel 116. The light-emitting diodes 142 comprise a means for providing visual feedback to a user inserting a card 120 into the bezel 116, as described further below. In the preferred embodiment, the light-emitting diodes 142 are dual light-emitting diodes capable of producing two primary colors and a third combination color.

Referring now to FIG. 6, an electrical schematic of the card reader is shown. The schematic includes the array of photodiodes 134 disposed along one side of the card reader opening 118 and the array of photodetectors 136 disposed along the opposite side of the opening 118.

For example, if either phototransistor PD 1 or phototransistor PD8 detect light, the voltage level on conductor 148 will drop from a high voltage of approximately 5 volts to a low voltage of approximately 0.7 volts. Without more information, the player tracking controller 98 would be unable to determine which of the two phototransistors, PD1 or PD8, actually sensed the light.

However, the card 120, as shown in FIG. 7A, includes a first slot 150 by which the PT controller 98 can determine which of the two photodetectors detected the light, as described below.

The card 120 includes five rows of slots 152-160. The rows of slots 152-160 are arranged in a matrix with the corresponding slot locations within each of the rows being aligned in columns. Only the first slot 150 of row 152 cannot be aligned with any other slots, slot 150 is in a column all by itself. The individual slots within the rows of slots 152- 160 encode unique player tracking information. Each slot represents a single binary bit in the player tracking information. Either one of two conventions can be used to encode the information. First, a slot can represent a binary 1 and no slot can represent a binary 0. Second, a slot can represent a binary 0 and no slot can represent a binary 1. The player tracking information can include: a unique player identification number, the casino issuing the card, player membership information, etc.

In the preferred embodiment, the card includes five rows of slots each having a maximum number of nine individual slots, thereby producing 45 possible slots. The first row of slots 152, however, is not used to encode player tracking information, but instead is used to synchronize the sampling of the player trackin g information by the player tracking controller 98. Thus, only 36 slots are used to encode player tracking information in the preferred embodiment. This still allows 2" 3G possible combinations, which is more than adequate.

The PT controller 98 uses the first row 152 to synchronize the sampling as follows. The PT controller 98 continuously samples the outputs of PD4 and PD5 looking for a slot. If a slot is detected on either PD4 and PD5 and no other slots are detected by any other phototransistors the PT controller 98 determines that the detected slot must be slot 150. The PT controller 98 then continuously samples the output of the phototransistor that detected slot 150. Once a new slot is detected by that phototransistor, the PT controller 98 then samples the outputs of the other phototransistors, PD1-PD3 and PD6-PD8, on conductors 148, 150 and 152 for slots in of the other rows. Thus, the PT controller 98 synchronizes the sampling of the other rows of slots to the detection of a slot in the first row 152.

It is important for the card reader to detect the orientation of the card in order to correctly interpret the player identification information is encoded on the card. The card reader detects the orientation of the card 120 by detecting the slot 150. If slot 150 is detected by phototransistor PD4, then the card reader knows that the card is in the orientation shown in FIG. 7A. In that case, the card reader knows that the player tracking information is actually being detected on phototransistors PD5-PD8, and can interpret the player tracking information accordingly. If, however, phototransistor PD5 detects slot 150, then the card reader knows that the card 120 is oriented 180 degrees from that shown in FIG. 7A. In that case, the card reader knows that the player tracking information is being detected by phototransistors PD1-PD4, and can interpret the information accordingly. The PT controller 98 can simply transpose the player tracking information sensed on conductors 148-152 depending upon the detected orientation of the card. Thus, the card reader .00 is able to correctly interpret the player tracking information regardless of how the player inserts the card 120 into the bezel 116 of the card reader. This can be accomplished with only five conductors beatweeni the eight plotasisLors PD) -P1)8 and te 1I' controller 98.

TPhe spm 10ti t alsoi allows Gir imrprovedl player trackiiig- As wit.1 standard player tracking, tie al)ve-descrilred system n ittors aol ,I0 reports how many coills are, played by each player. Th -ycstei n however, also includes the ability to record how long each player spends at each machine and the number of coins won, games played, and hand jackpots won by each player. All this information is stored on the database, which can be later analyzed for future targeted direct mailing campaigns. The player tracking according to the system also allows the casino to schedule buses and other groups and measure their profitability. The system also allows for cashless play as well as advanced accounting and security features.

Another feature of the above-described system is jackpot announcements. The jackpot announcement feature displays a message on a reader board or display located in the casino which announces a jackpot as soon as a jackpot is won, as soon as the reels stop spinning. The floor controller generates the jackpot announcement once a DCN connected thereto indicates a jackpot is won. An example of such a message might be: "Now paying on machine 1342, a jackpot of $300." With prior art data collection systems, the amount of the jackpot is only known after the payment is made.

Even then the system must account for partial pays, hopper empty, etc.

An advantage of the current system over prior art systems is the ability to implement better tournament systems. In a slot tournament, players pay a fee to play. All play during the session is free. The players accumulate credits instead of cash. The person with the most credits at the end of the tournament wins. Games are usually manually altered to provide payouts of 200 to 300% to make the games more fun. The games are altered manually by replacing the read only memory (ROM) in the gaming devices.

One exciting aspect of tournament play is to see who is ahead. No current system can display this information in real time. This is because current systems can only measure winnings as they are added to the credit meter or paid from the hopper (some casinos use tournament tokens instead). Since credits are usually added at a rate of 10 per second, a 1,000 credit win can take 100 seconds to register. Casinos attempting to create display boards showing who is ahead are frustrated by the lag time.

The jackpot announcement of the system allows casinos to display the player with the most credits by comparing the number of credits for each player. This comparison and display is performed real time as each transaction is completed.

In order to implement each of these features, the various computers and microcontrollers each execute software or firmware. This software and firmware routines are described below. These routines are described with reference to accompanying flow charts. These flow charts would enable one of ordinary skill in the art of computer programming to write a corresponding computer program which the computer or microcontroller could execute.

A. DATA COMMUNICATION NODE 1. POWER UP PROCEDURE Referring now to FIG. 13, a power up procedure 252 for the data communication node is shown. This procedure is executed by the DCN controller 46 when initially powered up. The first step of the procedure is to validate the RAM to ensure that it is not corrupted and to set up all the DCN hardware. Validating the RAM involves writing known patterns of 1s and Os to the DCN RAM. This RAM can either be internal to the DCN controller 42 or external as shown in FIG. 2. Setting up the DCN hardware includes initializing timers and interrupts.

Next the DCN controller checks the RAM in step 255 by reading the pattern of ls and Os back out of the RAM to ensure that the RAM is fully functional. If the RAM turns out to be defective the DCN controller goes into an endless loop in 256.



If the RAM is fully functional, the DCN then reads the unique identification number from the personality board. As described above, this unique identification number is stored in a nonvolatile memory 210 on the personality board. Reading the unique ID number out of the nonvolatile memory involves following the memory manufacturers interface protocol as specified in the nonvolatile Inemory data sheet. The unique identification number provides a means for uniquely identifying the gaming device.

lo After the unique ID has been read from the personality board, the DCN processes the discrete machine inputs in step 260. This step will be described in further detail in Subsection 3, MONITORING GAMING DEVICE DISCRETE INPUT below. After the discrete inputs have been processed in step 260, the DCN processes the machine serial interface in step 262.

is This step is described further below in Subsection 4, PROCESSING GAMING DEVICE SERIAL INTERFACE. Next, the DCN processes the network interface, the interface between the DCN and the floor controller connected thereto. The process network interface step 264 is described further below in Subsection 5, PROCESSING NETWOIK INTERFACE. Finally, o the DCN processes the player tracking interface in step 266. This step is described below in Subsection 6, PROCESSING (ARI) INSERTION. At the completion of step 266 the DCN loops back to step 260 and continuously, sequentially executes steps 260-266.

3. MONITORING GAMING DEVICE DISCRETE INPUT Referring now to FIG. 14, the DCN step of monitoring the gaming device discrete inputs 260 will now be described. The DCN first reads the discrete inputs on input lines 76 in step 267. One particular set of discrete inputs is shown in FIGS. 4 and 9 for a particular gaming device.

The actual discrete inputs present will depend on the machine type, as :o indicated by the configuration number, which is also read by the DCN controller 46. Most gaming devices provide at least some of the following discrete inputs: coins in, coins out, coins to drop, games played, attendant paid jackpots, slot door, drop door, progressive jackpots, and bill validators. The system supports all of these discrete inputs as well as others.

The DCN keeps track of the machine activity by maintaining several meters in memory. Each meter, in the preferred embodiment, includes six digits. Moreover, to improve the reliability of the system, the DCN maintains redundant backup copies of these meters with an o1 order to replace the original meters in the event that the originals are corrupted. In step 268, the DCN increments the meters as required based on the discrete inputs. The meters are maintained even in the event that the DCN is disconnected froin the floor controller. Once the DCN is reconnected to the floor controller, all the activity level information is is then available. Step 268 will be discussed further below.

Next, the DCN processes the drop door signal in step 270. The drop door signal DROP DOOR indicates that the drop door on the machine has been opened. This is an important event and is therefore processed separately.

In step 272, the DCN validates the meter values to determine whether the values stored in the meters are valid. The DCN checks whether the meter values are valid in step 274. In the preferred embodiment, a check sum is maintained for each meter value. Thus, the DCN in step 274 checks to see whether the check sum is correct based on the current meter value. If the meter values are okay, the discrete input monitoring step 260 is complete. If the meter values are not valid, the DCN replaces the meter values with the redundant back copy of the meter values in step 278, and then the step 260 is complete.

Referring now to FIG. 15, increment meter step 268 is shown in so further detail. The sequence shown in FIG. 15 is repeated for each meter value that has changed. The first step is to adjust the meter value based on the discrete inputs and to calculate the associated check sum. Next, the DCN determines whether the particular meter has an active associated countdown count in step 282. Some ganes or promotional activities require the player to reach a certain level of activity in order to be eligible for certain bonus points These countdown counts are used to determine whether thile player has achieved this level of activity. For example, the player may be required to play a certain number of coins before being awarded any points. If tlhe countdown count is active, tile to D)CN adjusts the current players count down values in step 284 based on the corresponding adjustment of the associated mnter.

In step 286, the DCN sets the current message to the count down message. The count down message inlicates to the player when he or she will be eligible for the bonus points. Finally, in step 288 the DCN sets the is current bezel color and rate to a count down color and rate. This color and rate information is subsequently transmitted to the player tracking node for processing, as described futrther below. T'he count down color indicates the bezel color and the count down rate indicates that flashing rate of the bezel color displayed during the count down m(essage.

4. PROCESSING GAMING DEVICE; SERIA INTERF'ACE Referring now to FIG. 16, a I)process 262 for processing the gnmning device serial interface is shown. The serial machine interface 60, as shown in FIG, 2, allows the DCN controller 46 to communicate wvith the giraming device through the personality board. This serial inrachine 2s interface allows the DCN controller 46 to transmit reconfgura ion commands to the gaining device in order to reconfigure the payout schedule of the machine in accordance with the reconfiguration command.

In addition, the serial machineinterface provides an additional means for determining the activity level of the gaining device. Instead of reading I( the discrete machine inputs, the DCN controlier 46 can transmit a status request command to the machine over thre serial interface and the machine can respond back with the requested status informiatLion.

Any comnmunication protocol can be used to implement this commnunication path over the serial machine interface, as is known in the art. An examnple of one such protocol uses a data packet including a comm11and code, a mnessage sequence number, a CRC, arid a variable length mnessage. In the preferred emnbod itmentt, either the DON controller 46 or the machine can iinitiate comimunications over thle serial machine interface. Ilowever, if the mnaclime detects that the DON is trying to send a message to the~ machine, the mnachine miust abort its InC5ss-agC and attmipt to resend the nissago at a later timle.

Tb he preferred cml ioU irnent of the system supports iany different, reconfiguration cotriniaids, A partil l-st of the reconfigiration command1,s is given below in, Tlable L. These rcconkgtratiozi coa'inandis lire sent from the 'DON controller 46 to the inachine over the serial machine interface wherein the nachi ne reconfi gu~res its payout schedule in accordance with the partLicular reconfiguration coniiniaid. The reconfigution 10 c011ITflliflis do not originate with the DON, instead the recOnIi guiratifon commamnds originate fr-om the floor controller anid are transmitted to a particular machine over the associated current loop network or the coinmaznd can originate at one oif the other computers oil the high speed network. The DON is simply responsible for forwarding thle reconfiguration commvrand onto the gaming device on receipt of thle reconfiguration commiandl over the associated current loop network coupled between the floor controller and the DON.

Bonus Pay fromn Hopper (Dollar Format) 4, Bonus Pay To Credi t Meter (Dollar Format) Add Non-cash outable credits to Game 6. Begin Double Jackpot Time 7. Stop Double Jackpot Time The actual process of processing the machine serial interface begins in step 292 wherein the DCN polls the machine to determine its level of activity. This polling step includes sending a status message from the DCN to the machine over the serial machine interface. In response, the machine will send a packet of status information indicating the current amount of activity on the machine. The status information included in the response will depend on the type of machine that the DON is commnunication with.

The data communication node 42, in step 294, waits for a reply to the status request. If a reply is received, the DON indicates that the r, machine is "on line" in step 296 and processes the machine reply in 298.

The step of processing the machine reply includes updating the meter values, as done when processing the discrete inputs. After the machine reply has been processed, the process 262 is complete.

If the DCN does not receive a reply from the machine in step 294, the DCN indicates that the machine is "off line". The DCN will wait for a predetermined amount of time before deciding Ltat the reply is not received. In the preferred embodiment, this predetermined period is approximately 110 milliseconds.

PROCESSING NET'WORK INTERFACE Another step in the DCN power up procedure 252 is the step of processing the network interface 264. This step is described with reference to FIGS. 17-19. The network interface refers to the current loop that connects the particular DON with the associated floor controller.

The following description assumes that the DCN has received a valid so message from the associated floor controller. Because there are multiple DCNs connected to any one current loop, the floor controller must include some means for addressing a particular machine.

Although each machine includes a unique identification number which could be used as the actual address for each DCN on the current loop, it is unnecessary to use the unique identification as the actual address because there are only a limited number of DCNs connected to each current loop. Accordingly, in the preferred embodiment of the invention, the floor controller uses a shorthand token representation of the DCN's unique identification number to address the DCN. In the Io preferred embodiment, a single byte address is used to address a DCN on any given current loop. This one-byte address allows up to 256 IDNs to be supported on any given current loop network. In the preferred embodiment, however, only 64 such DCNs are connected to a single current loop and therefore the single byte address is more than adequate.

is The single byte address substantially reduces the amount of traffic on the current loop network by reducing the number of bytes from four in the unique identification number to one for the shorthand token representation.

The floor controller is responsible for generating the unique single byte address for each data communication node on a given current loop network. The process of assigning unique single byte addresses to the DCNs is described below in Section C.

Once all the DCNs have been assigned a unique address, the DCN can begin monitoring the current loop network for messages addressed to it. If the DCN detects a message addressed to it, the DCN executes step 264. The DCN first checks to see whether the message is valid in step 304. This check is done by computing the CRC value of the message and comparing it to the CRC included with the message. If the two CRCs match, the message is valid and the DCN processes the network message o in step 306. Processing the network message is described further below with reference to FIGS. 18 and 19. Once the message has been processed, the DCN sends a reply back to the floor controller over the current loop network in step 308. The actual substance of the reply will depend on the message received in step 306. If the message is invalid, the DON does not reply.

Referring now to FIG. 18, the first step of processing the network message is to determine what type of message was sent from the floor controller in step 312. There are three basic types of messages that the floor controller sends to tIhe DC.N. The first is a request for data from the io DCN. If this type of message is detected the DCN builds the data requested and transmits the data in a reply message. The main use of this message type is to gather status and meter idormation from the


Another type ofmrnessage is one including configuration data for the is DCN. This messnge allows the floor controller to implicitly set the DON's memory to a fixed value. This message is used to override the DON's internal variables, to get a DON out of a lock-up condition, or to download new firmware to the DON forexecution. On receiving this type ofinessage, the DC)N simply overwrites its memory with the configira tion o data included in the configuration message in step 316, The )CDON then builds an appropriate acknowledgment and transmits this acknowledgment message to the floor controller in step 320.

The other type ofmessage is one sent in response to a DCN request.

The DCN processes this data in step 318, which is described further in FIG. 19. If the message includes either the con figuration data or the data in response to a DCN request, the DCN builds an acknowledge message in step 320 and transmits this message to the floor controller.

The step of processing a floor controller message sent in response to a DCN ri-equest will now be described with reference to FIG. 19. The first step of processing this type of message is for the IDCN to determine what.

type of data is included in the mressage. Once again there are three typ~es of data that can be included in this mnessage type: a reconfiguration command, card dlata, or other minor data. The DCN makes this deteninin.AtiOn1 in step 324 by analyzing one of the bytes Iii the data packet of the message. This byte will be referred to herein as the command byte.

If the command byte indicates that the mnessage contains reconfiguration danta, ic., the command byte equals a reconfigura-tion command, the DCN stores the reconfiguratLion data in a predefined data structure in mlemory.

Listed below in Table 2 is an example of a data structure foir storing the reconlfiguration data.

Table 2 Re corifhgurahton Data Structure J Bonlus Type 12. Mystery Jackpot Data: IsA. Numnber of coins to award B. Number of seconds to award C. Pay award to 3. BOnIUS Time Data A.

If the mystery jackpot is indicated, the mystery jackp)ot data includle'] in the structure specifies the. conditions under which the mnyster-Y jackpot. is Paid out. The mIystery jackpot can he set to payout, e.g.,,after a certalin number of coins% in, handle pulls, which is Specified by subfields of the mnystery jackpot data.

The bonus time jackpot is a promiotion wherein the machine pays OUt More than that dictated by its default payout schedule., In one embodiment of the bonus time promotion, the payout schedule of the machine can be modified to be a multiple of its default to payout schedule, as specified in subfield of the bonus time data. This promotion can be used to encourage gaming activity during off-peak hours, midnight to 4 a.m. on weeknights. Alternatively, the bonus time promotion canll be activated on a random basis. The timning of the multiple jackpot is specified by the casino on one of the computers connected to the network.

The bonus time data also specifies the conditions under which the player becomes eligible for the bonus time jackpot. The subfield of the bonus 1o time data specifies whether the player is eligible for the bonus tirne data only if the player is playing the maximum coin in the machine. Subfield limits the bonus time proinmotion to a predetermined llnumber of seconds. This field limits the bonus tine promotion to a predetermined number of seconds; if the player does not hit a jackpot wilhin this is specified time period, the bonus time promotion concludes. The minimum activity level can also be specified in subfield This field can be used to specify the minimum activity level required by the player in order to be eligible for the bonus time jackpot. For example, the player can be required to play at least 20 coins over the last three minutes in order to eo be eligible for thile bonus time jackpot An indicator light onil the player's machine can he used to indicate when the player reaches the minirmu activity level and thereby becomes eligible for the bonus timlle jackpot.

In another embodiment of the bonus Lime prominotion, a bonus amount is awarded in addition to the payout according to the default of s the payout schedule of the machine. The aimount of the l)onus jaclkpot is specified in subfield of the bonus time data. For exmnple, this bonus tirme promotion might include five bonus amounts of $10, $25, $50, $100 and $500, which is specified by subfield When a player hits a particular jackpot, whichever bonus amount is specilFied by the bonus .s amlount subfield this amount is automatically paid out in addition to the payout amount determined by the machine's default payout schedule.

This bonus time promotion can also be used in combination with subfields and to specify the conditions under which the player is eligible for this bonus time jackpot award.

After the DCN has stored the reconfiguration data in step 326, the DCN will then send the appropriate reconfiguration command to the machine over the serial machine interface in step 328. The machine, responsive to the received reconfiguration command, reconfigures its payout schedule in accordance with the received reconfiguration command. For example, if the reconfiguration command specifies a multiple jackpot condition, the machine will reconfigure its payout to be a multiple of its default payout schedule. The machine will reconfigure its payout schedule in a similar manner for the other bonus types.

The other type of data that can be included in a response from a s1 DCN request is card data or player tracking data. This data is sent to the DCN in response to a status message from the )CN to the floor controller wherein the status message indicates that a player card has been inserted. Included in this message is the card ID number detected by the card reader. In response to this status message the lloor controller will transmit a card insertion message to the DCN. The card insertion message includes information associated with the particular player ID number. An exemplary card insertion message data packet is listed below in Table 3.

The next step in the DO)N process is processing of the player tracking int.erface 266. The IF ,N ra int ains a variabde that indicates what mnessage is to be sent Uo the pla~yer traickin node T his variable is referred to as the current miess-age vaiable. NBfore transiiiitting a mnessage to the ployer trackin node, the DC:N I-i rs'tcheck this variable to see which oif a plurality of nies-uges 'houl I he Sent to the player tracking node.

The process 2-66 begdis in 340 by sendhigthe currentmeisage to the player tracking node that is specified by the current message variable.

In addition to tie current mnessage, the DCN sends the bezel color andl "s bezel rate infarnmnon to LIwx pl aver tiack inig node. The bezel color anid bezel rate infot maGtin could have been specified by the floor controller or by the DC N itself.

Next, the DON determines the card status in step 342. If there is no caird in'serted in the card! reader, the DON sets the uurrent, mressage so variasble to an attract mecssage. This message specifes that the player track-ing node is to d "spl)1ay a mlessaga whlich will -attract players to the maehnQ. iml-ila, th.9Nst the curren t bezel color and bezeli rate to a atrac beel olor and rate ill step 346- T~his attract color adrt is part of the attract mnessage that wHilb sent to the player tracking node When the currunt oea is S'ot if tile DCON determtines thait a good card hias been inserted ini thel( cad reader, thw DON Owoe e h vailid card in stiep 350.

157. Pitocrssih( CARD INSERTION Ref'ering njow to P11-24, the: process 350 for processiii(" a Vahd card insertioli is sliown, Th'e( first step that the DON executes is to dletermnine wheter the card data corrcesponding' to the valid card has been receiv(cil fromn the floor con trllebr in step 356. If riot, the DON huils a network n's ige fe- the p1lyer narruie and poinlts associated with thle card ID umer n tep'358. Next, the DON sets the currn nis vai dde to specify a card inserted message is to be transmnitted inl step 360.

Finlly, the DON sets the current. bez~el color and rate to a c ird insvi-ted color- aind rate, which indicates to the player that. the systen is still processing the card nuinter. This in forinatiol is sent to the plaiyer trckn node when the currenft tie-sage is et If the card data has been received fromi the floor conti oiler, the DOIN thenl determlines in step 366 whether player tracking has st'm3rted for the particular player. .I fplayer tracking" has riot yet started, the DON sets the socurrent. niessage vaiabla to the data received mnessage inl step a a d 0 sets the current bezel color and rate to data received color and rate in step 370. If player tracking has started, the DCN processes the player tracking in step 372, as described with reference to FIG. 22.

Processing player tracking 372 begins with the step of determining whether the player has received new points in 374. These points can be considered roughly as the equivalent of "frequent flyer miles" used by airlines. These points allow the system to run promotionals whereby individuals are given points or credit associated with their card that can be redeemed toward the purchase of goods or services offered by the casino.

Typically these points are redeemed at a redemption counter in the casino for meals or clothing, for example. The points, therefore, are an additional inducement to encourage play.

The player tracking system allows the casino to determine how and when the player is issued points. The casino can specify the type and number of coins that must be played before a player is awarded a given number of points. The system uses this specified information to inform the player of his or her progress towards receiving additional points. The system encourages play by informing the player of how many additional coins must be played before receiving additional points. For example, a player who is only one coin away from receiving points, but who desires to stop playing, may decide to play "one last coin" in order to receive the points. The system informs the player by displaying a message on the vacuum florescent display indicating how many coins the player is away from receiving additional points.

Referring now to FIG. 22, player tracking 372 begins with the step of determining whether the player has received new points in 374. If no new points have been received, the DCN sets the current message variable to specify a countdown message in step 376 and sets the current bezel color and bezel rate to a countdown bezel color and rate in step 378.

1'he countdowii bezel color and ra te indicates the player's, progress towards be-,ing awarde d additional points.

If new points; hve been, received, such as where the player has played a given nunhi of coins. the i)CN sets the current message variable to a points Nwon inessage in step 382 and sets the current bezel color and rate L.o a points won color and rate in step 384, Tw points wvon Txiesaig( mnfoi rins the player of the numiber of point-swn Th~le above-descrilied tracking proess p rovide a nieans for providin ii enl feedbnck to tie player inserting the- ca rd into the card reader.

The~ syster described above allows for improved player tracking by recording each andI every imacline transation including: timle of play, rrachiinc, number, iluratni (if play, coins in, coins out, hMn paid jackpots ~o andc gaines played, The player tracking is cond ucted over thme samne network as the accounting data is extracted. This allows the system to provide bonusing to certain individual players as well as during certain times. As with standard player tracking, the above-described system monitors and reports how many coins are played by each player. The system described herein, however, also includes the ability to record how long each player spends at each machine and the number of coins won, games played, and hand jackpots won by each player. The system is able to record all this information because the it operates on a transaction by transaction basis. Each transaction, whether it be a coin in, a handle pull, etc., is recorded by the system. Other prior art systems simply compile the player tracking information at the completion of play.

All the transaction information is stored on the database, which can be later analyzed for future targeted direct mailing campaigns. The player tracking allows the casino to schedule buses and other groups and measure their profitability. Because the system records each transaction, the casino can reconfigure their casinos to better match the tastes and demands of their customers.

This improved player tracking system also allows the casino to calculate theoretical wins exactly because the system always includes the most current information. The operation of the player tracking procedure is described below.

1. POWER UP PROCEDURE The operation of the player tracking module will now be described with reference to FIG. 23 where the powerup process 400 for the player tracking node is shown. As in the data communication node, the player tracking node first validates the RAM and sets up its associated hardware in step 402. Next, the player tracking node tests the RAM in step 404 to determine whether the RAM is functioning properly. If not, the player tracking node, player tracking controller, terminates its program in an error condition in step 406.

Another step that the floor controller executes after becoming operable is to place an initial machine search message in an output message queue 470. This search message is used by the floor controller to determine which machines are connected to the floor controller. This output message is subsequently transmitted to all of the machines coupled to the floor controller using a global message format, as described below with reference to FIG.

31. In the preferred embodiment of the system the message handling is through the use of message queues. Furthermore, the preferred embodiment is both an output queue for outgoing messages from the floor controller to the machines and an input message queue for messages coming from the machines to the floor controller. Queues are well-known data structures in the art of computer science and are therefore not further discussed herein. Alternatively, the message-handling could be done without the use of the queues. In such an embodiment the outgoing messages would be sent immediately rather than being queued, and any incoming messages would be processed immediately.

The bulk of the work performed by the file server process 464 is performed in message processing step 472. In this step, the floor controller processes all messages sent to or received from the machines connected thereto. This step will be described further below with references to FIGS.

29 through 31.

The process 464 also includes a system monitoring step 474. This system monitoring step 474 administers certain system-wide events. These system-wide events include the counting-related events and bonusing events. The floor controller continuously checks to see whether any of these events have been triggered. If any event has been triggered, such as a bonusing event, the floor controller takes the appropriate action to handle the event. The event may be triggered by the time and day or by user nterv(,ltifo o(ther eTvent Th'e system mionit-oring step 474 will he dlescribed furthier below with reference to FIGS. 32 and 33.

The floor corntrollerchecks in step 498 to determine whether the mnessage includes this type of information. IF the ruessaige Kiclues new miete information, the floor controller saves the new mneter locally in step 500, TPhe floor controller ma intlains local copies of tHie meter inform-ation in order to in iniirnize the an tount of traffbc oil thei high-speed. network. 1ecause Hie ic acine inc I e an ilge so rapidly, forwarding this new meter m formationi on to the Mie serer eMc tie one of these mreters is YO %mre ould pr-od iw aii excessive amount Wf i t work tra ffic oni the hli 'h l oe netw, ork.

Typically, these, dat'a roque. is will be For player tracking,, inform'Tation such as whee a player inserts a cad into a cardl reader whereUp)on tile data coinmuni.(cation associauted therewmith sends the identification number encoded on the, card to the floor controller ~o requesting the player tracking data ass~ociatedl with the player identification number. If the floor contrller10 detects a data re!quest ill step 502, the Nlor controller looks up the reqluested data in the database on the file server in step 504. Also, in step 504, the floor controller mnarks a, response pending in the trasactions in progress structure to irlcicate, that this requested data needs to be soul back to the DCN. As dascrihlsd above, the Floor controller qi icues up out going messages responsive to the tr-ansactions in progress structure.

Another message type is one used by the floor contololer to estabish new mach ine add resses. The Floor contrxoller periodica-lly checks to deterniine wheithler any new D(N has been) coupled to its as~sociated ,current loop networks in order to assign a unique address to that mnachine. In step 5106, the floor controller cheeks to see whether the incoming m~essagILe is in response to such a process. If the i nco m ing rnessin'C is in response to a machine search the floor controller assigns S a new machine address to the responding ra,-chike in step 508. The entire Process of assigning new macwhine addresseqs is descrr~bed beluw with reference to FIG. 31.

Finally, the floor controller in step 5 10 hanlleI-S any Mniscellaneous messages. These mniscellanie'ous messages- are ised primarily For debuggiii and trotlblet-ShOOting the machines.

3- ARsSIGNING GA.MING DEVICET V)DRE.I S3F As described albove, in the preferred embohdimlent of thie invention, the floor controller uses a shorthand toen representation of the DCN's unique identification number to addres-s the D(N. fin the preferred unbodiment, a single byte addnes iA used to ddres a DCN an any Oiven current loop. This one-byte address allows up to 256 L)CA to be supported on any given current loop n(twork. Iii the prefe rred embodiment, only 64 such DONs are -onntecte d to ai singloe urrMit loop network and therefore the single h~yt.e address is inore thanu adlequate.

The sEnle byte aidldress substantillY reduces th-imul tof traf'llc of the current loop networK by reducing the numnber of bytes From four iii the unique identifitaion numrber to one f'or the shorthand Whoen represenltation-.

The floor controller is responsible, for generating the unique single byte address for each data communication node oni a given current loop network. The process 508 of a.,-signing unique addi esses, to the DONs on the current loop network is shown in FIG. 31. The process begilns by defining a range of unique ideruiCcatioli numbers in step) 512. Initially this will be a large range.

Next, the floor conitroller sends out a Insag to i ftei~a the cturrent. loop network in step alt4 The floor controller commnunicateas with the I )ON by using a standard caminnmca ti)n protocol. In the preferred embodiment, ths protocol defines a mnessag~e Formnat including, a destination ID, a source 11t) a rnessaigy inthi a d At pua ct Ad a CRC.

4. SYSITNI MON VI'M)IN( Referr ifg now to VIIG 32, the systemin olitoriljag s!tep 474 %vill now Is be desc.ribe d, The floor controller is now responsible for nmonitoring certain Systeni-xVide mu)ihions to determine wvhetfiert crtain events nee(l to occur. The System mneitorinig step also hanidles request for pa"rticular lmachine information. Th us, in rtepj 524, the floor controller (letertiincs whether a new rQ~luest has bMen placedl in the data base for such 2o particuilar machine inforaht Ioif such a request lIt,)s beeni placed, the floor cmntroler respon rds to Hte special repieust. for dat in step 526 by sending a, nessage to the pa rticular machine requesting the required informati~n. Once the required information has been received, the floor controller processes this infourmationi accord ingly.

2! The floor eon troller also mn li tars the locally-sto0red Meter informnation inl step 521 If tIw ie baly-stored in formation is chan1gedl,th Dloor controller saives the latest inforrmat ion to thie data base! in step 530.

As described above, the floor cont roller saves the mieter information locally in ordr to mininiee the( traffic to the h be server over the high 21) speed network.

The floor contrl-aler a].so mownitors the systern for Certaiin event triger insto 53. hese triger c(a he stored in the d ata base and fetched by the floor controller during its power Op procedures- These triggers indicate if and1( when certain evets occur. Examples of event triggers include: the dro,)period, the en~d-ni'-day, the I)OTIS period, etc.

Ifan event trigger has occurred, the flour con troller hli dl es the event in step 5M4 Thel( handle event step 53i4 is shown ifl more detail in) FIG. 33. The events can basically he bifurcatod in to accounting events and botusing everlts. conigeetee otedt o~~~iit~Iatv~yo h systeml Tlhe accounitling evenlts :l typically triggre~d by a certain tiule of day s-uch ais the end of day or the d:rop period. If an iccouinfg evet has been trimgyered, the floor controller peribris the required data b ase ojperationsi in sop, 538 Th is step involves updLatig A of the locall- Qstorild miet er inorinatin and smng tho updated nleter in flrmation into the data base.

Th'le other type of event. can be(. referred to as a housing event. The floor controler chiecks to see whether the event, is a bomuminr evnt, in step 5401. The bonusing events can also he( trigg,,,ered by the time of' day, For example, the bonusing ewmntma yb A rgeem onniduidit, to 4MO) a-in- onl weekdays. These henasing pcriocs can be specified in thr &Knt base. If the triggered event, I a bonusig even, the floor contracl ,r inserts at corresponding reconfiguration message in the out~put, message queue in step 542. The rec*onfiguration nmessage incloles a reconfiguraton cumnind that is scent, to an appropriate machine. The machine, upon rt cr n the rEomoifiguratiori command, ieconfigures its payout schedule in accordance with thc received reconf iguraf ioni comanid. Acc-ordi m to the invention, there are inany differenit reconfigurntioti comma nds to implemen~rt a multiplicity oif different :m0 bonusiri events One rconfiguratiori cormmand spe~cifies that, the ma-,chinle should reconfigure its payout sc hedule to be a1 multiple of its defaul payot schedule. This, reconFirm rat in icomn a ls pcf that thef, multiple payout schedule should be limited to a predetermined percentage of the coins in. This rconfig~urationi command can further specify that the inultiple payouts'choduh slhould bIe limTed to only mwen the roaxinkun coins are played. Tis reconfignratioil command can hi rthcer specify tiat the umdtiple payout schedule Owld to imited to paYouts in a specified range. ThS reconfiguratin command can also specify the multiple payout schedule should payout only when a1 o0 predeterinetd level of player activity is reached.

Another reco nipg ion commn allows any nuibohr of machinus on Ohe network to be combined in a commtion jockpoxt havin g a common jackpot payout sche(dule, whe rein the reco fl guratbii coimmnan d reconfigures the seleed tmchines to payout in accordance withi the commnon jack pot payout scheduile. In this case, tOwi recon figuration mnessage would he qu~euied up for each of the seletd machine's to be comined in a coinnon jackpot. One example of a common jackpot is a progressive jack pot. UinlIike the~ pri or art progrev jac pot sy stern, however, the! progressive jackpot according to the invention is not limited to a predeteruined num obr o macbines. In the Qpio art protgresim jackpot systemns, a bank of machines are connected to( a CoOn1 progressive jack pot controller and only those machines can be jole in the progressive jackpot, In contrast, any, macine on the network, including those connected to other Dloor controllers can he cmnin iid into common progressive jackpot. bloreover, the number of progressive jack pots is not Ui nited by To number of Bloor controllers since one Dloor controller can manage moire than one propresive jackpot.

Anoter rconfguraioncom1mand pernits the-systein to inipleinen t so-called "anItonmatic nmystery jackpoLs-" These "mystery" jack pots allow a inach ine to pa-yout a mnystery jackpot even whlenn aackpot was not won- Instadtherecorufigura t ionl couimand Canl specify thattemytr jackpot is to oc cur -ifte(r a certain number of coinls, a. certainubro hazndle pulls, or ava~rie ty of other conditions specified by the reco 01 guratioIl conuads.

Ile uethod c55) begin in step 552 by disabling or turning oil the bonuises in the individ ua machines- Tb is is accomplished by sending a rnessage to the individual 1)CA to turn offor deactivate boniusiog, Nelxt, the Dloor coMnte mnonitors the activities of the individlual mnachinles connected th ereto. This step includes monitoring the coins inl and bonluses paid for the individual niachines, as des~cribed above. Inl step 5561 the floor controlle.r modifies a bonus pool 1y a predetermirned percetage of all coins playedl. The b.onus~l pool is e;sentlially a pool oif mnonetary resources that, can Ine. allocated for bonuis awards. In the preferred embod iinrent, a predleterm-ined percentage of the rnonetay value of the coins played are added to the bonus pool. Also i ths step, any bonuses paid by the gamring devices are als-o rneasured a nd subtraclted From the bonus pool. The use of the bonus pool will becomne more apparent when the other steps are (lemcried lbereinbaow.

In step 558, the floor controller determnines whethcr or not bonlusiog is active. If honiusng is act&v, the Door controller next determnes whether the bonus pool amiount has dropped below a predctcrrniiied no mnimumi level called the "lurn- off level in 560. 'ph minimum amount or floor can be set by the casino and provides a buffer to accounit for- largxe Lonus awards and/or u] tple bonus awards that could cause thle bonus payout to exceed the bon us pool. Tb leref'ore, ifthe bun is pom drops below the turn-off ltee, the WethN 550 bra nches back to step 552 and~ turns odlbonnsinig. As will described further belo w, the bon using remains off until such time as the bonus ol builds up1 past, .1 otl icer uoiillniI level WINe the thun-on" level.

Returning to step) 551 if the bonus is currently riot active, the floor controller ileterntines at step 5621 whether Lhe bonus poo b as reachedn a H) preIetecinined turn-on leOe. This tun-on level ca n ailso hnet by the cu1llio andl proi vdes a bulker ab~ove LBei to rn-off level to. inure that the' blousin!.' does not behave erratically, i-e, Don using rapIid~ly switchinig between an and oMIf Btte lWonos poo l i s not above the turn on level, bonusing is ignin turned off in step 5:52.

1I the bonns pool has reachied thle tulrn--on level, the Floor coIntrolle r checks to see whether other boinis corditions are mett at step 564. These bonus cond itiouns can include butare not limited to, a ininimumi period( ot time si ne I h last bonus air ion, a in inhiinun level of play in the tinie pei od prior to the bonus pool reaching the turn enI level, a 2n pi-edet erimoed I one of day, or oTer predeterinilned ondtiony s Thse conditions give the casino additionial control ior the haniusi g ptrmotions. If the conditions are not. iet, the meithod 5.50 branches back to step 552 where the honusing is again turned ol Kf, bow ever, the conditions are nmetin step 56-1,heblonns is tki riedton at step 566 and the es method 551) branches to step 554 where the machine acti vity is again inn itored.

In the preferred embodl)(iment, thl mnethod 550 is embodied ini software thA is executed by each of th~e floor controllers iii the systemn.

These floor controllers are then responsible for actiating or deacivtng Wo the bonusiN; fur the inolivid nal machines coon ectod thereto. The systemn -70/1 allows the floor controller to have multiple bonus pools and to have certain of the machines associated with a given bonus pool. Thus, the floor controller can implement multiple bonusing promotions simultaneously.

This system also allows for machines connected to different floor controllers to be combined into a single bonusing promotion. In this case, one of the floor controllers assumes primary responsibility for managing the bonus pool while the other floor controllers act as intermediaries between the primary floor controller and the machines connected to the other floor controllers. Thus, the system according to the embodiment allows for much greater flexibility in running bonusing promotionals than heretofore possible. Prior art systems required certain predetermined machines to be connected into a bank for any given bonus award such as a progressive bonus. The system according to the embodiment allows any machine in the casino to be combined in a bonus type situation. The system also insures that the bonusing promotionals will operate substantially in the black, the bonus pool is greater than the bonus payouts.

III. PREFERRED EMBODIMENTS OF THE PRESENT INVENTION Embodiments of the present invention will now be described with reference to FIG. 35 to Turning now to FIG. 35, indicated generally at 1010 is a schematic diagram illustrating electronic gaming machines (EGMs), like EGMs 1012, 1014, interconnected by a computer network. Included therein are three banks, indicated generally at 1016, 1018, 1020, of EGMs. Each EGM is connected via a network connection, like connection 1022, to a bank controller 1024. In the present embodiment of the invention, each bank controller comprises a processor that facilitates data communication between the EGMs in its associated bank and the other components on the network. The bank controller 1024 also includes a CD ROM drive for transmitting digitized sound effects, such as music and the like, to a speaker 1026 responsive to commands issued over the network to bank controller 1024. The bank controller 1024 is also connected -70/2to an electronic sign 1028 that displays information, such as jackpot amounts and the like, visible to players of machines on bank 1016. Such displays are generated and changed responsive to commands issued over the network to bank controller 1024. Each of the other banks 1018, 1020 of EGMs include associated bank controllers, speakers, and signs as shown, which operate in substantially the same manner.

Ethernet hub 1030 connects each of the bank controllers associated with banks 1016, 1018, 1020 of EGMs to a concentrator 1032. Another Ethernet hub 1034 connects similar bank controllers (not shown), each associated with an additional bank of EGMs (also not shown), to concentrator 1032. The concentrator functions as a data control switch to route data from each of the banks to a translator 1036. The translator comprises a compatibility buffer between the concentrator and a proprietary accounting system 1038. It functions to place all the data gathered from each of the bank controllers into a format compatible with accounting system 1038. The present embodiment of the invention, translator 1038 comprises an Intel Pentium 200 MHz Processor operating Microsoft Windows NT Another Ethernet hub 1039 is connected to a configuration workstation 1040, a player server 1042, and to bonus servers 1044, 1046. Hub 1039 facilitates data flow to or from workstation 1040 and servers 1042, 1044, 1046.

The configuration workstation 1040 comprises a user interface. It comprises a personal computer including a keyboard, Intel Pentium Processor and Ethernet card.

The player server 1042 comprises a microcomputer that is used to control messages that appear on displays associated with each EGM. Player server 1042 includes an Intel Pentium Processor and an Ethernet card.

Bonus servers 1044, 1046 each comprise a microcomputer used to control bonus applications on the network. Each bonus application comprises a set of 72 rules for awarding jackpots in excess of those established by the pay tables on each EGM. For example, some bonus awards may be made randomly, while others may be made to link to groups of EGMs operating in a progressive jackpot mode. Examples of bonuses that can be implemented by bonus servers 1044, 1046 and a network that could be used to implement the present invention have been hereinbefore described in the description of the system and network with reference to Figures 1 to 34.

FIG. 36 is a highly schematic representation of an electronic slot machine, which is typical of each of the machines in the network, that incorporates network communications hardware as described hereinafter. This hardware has been hereinbefore described in the description of the system and network with reference to Figures 1 to 34, and is referred to therein as a data communications node.

Included in EGM 1012 are three reels, indicated generally at 1048. Each reel includes a plurality of different symbols thereon. The reels spin in response to player input after a wager is made. FIG. 40 comprises the paytable for EGM 1012. The first three columns depict different combinations of symbols on the reels. The fourth column of Fig. 40 indicates the amount won on a single coin wager when the combination of symbols in the first three columns appears after the reels spin. Columns five and six indicate the amount won when two and three coins, respectively, are wagered. Any combination of reel symbols other than those shown in FIG. 40 does not result in a payment to the player.

The network communications hardware preferably comprises a machine communication interface (MCI) 1050. MCI 1050 facilitates communication between the network, via connection 1022, and microprocessor 1052, which controls the operation of EGM 1012. This communication occurs via a serial port 1054 on the microprocessor to which MCI 1050 is connected.

Microprocessor 1052 is also connected to a programmable read only memory (PROM) 1056, which controls the behavior of EGM 1012, and which may or may not include the paytable of FIG. 40, depending upon how the present invention is -73implemented, as described hereinafter. MCI 1050 may include a random access memory (RAM), which can be used as later described herein.

MCI 1050 also facilitates communication between the network and a player display 1058, a card reader 1060, a player-actuated push button 1062, and a speaker 1064.

Card reader 1060 reads a player-tracking card 1066 that is issued by the casino to individual players who choose to have such a card. Examples of a suitable card reader 1060, player-tracking card 1066 and player-tracking systems have been hereinbefore described in the description of the system and network with reference to Figures 1 to 34. Briefly summarizing such a system, a player registers with the casino prior to commencing gaming. The casino issues a unique player-tracking card to the player and opens a corresponding player account that is stored on accounting system 1038 (in FIG. 35). The account includes the players name and mailing address and perhaps other information of interest to the casino in connection with marketing efforts. Prior to playing one of the EGMs in FIG. 35, the player inserts card 1066 into reader 1060 thus permitting accounting system 1038 to track player activity, such as amounts wagered and won and rate of play.

In another embodiment of the invention, EGM 1012 in Fig. 36 can be operated in a stand-alone mode, without connection 1022.

Consideration will now be given to the operation of the network and associated equipment depicted in FIGS. 35 and 36. First, selected configuration parameters are implemented at each EGM. As discussed above, these configuration parameters may be implemented by either installing a PROM, like PROM 1056 in FIG. 36, in each EGM to be configured or by placing the EGM in a configuration mode and thereafter generating inputs to the EGM, or a combination of and Alternatively, and also in accordance with the present invention, configuration parameters can be implemented by generating computer commands at configuration workstation 1040 that are transmitted via -74the network to a selected one or more of the EGMs. For example, and with reference to FIG. 36, such commands can be transmitted over the network to MCI 1050 via connection 1022. The commands may either reside in the random access memory (RAM) contained within MCI 1050, or can be transferred to RAM (not shown) associated with EGM 1012 via the serial port 1054 of microprocessor 1052. In the latter case, the code so transferred is received by microprocessor 1052 and then stored in the EGM RAM.

In either case, whether stored in MCI 1050 or in RAM associated with the EGM, the configuration parameters are accessible by microprocessor 1052. which when programmed with the stored configuration parameters causes EGM 1012 to operate in accordance with the parameters. As mentioned above, such configuration parameters control the behavior of the electronic gaming machine and may include the paytable that controls the average percent of money that the machines returns to players via jackpots.

Next, a plurality of variables related to play on the gaming machines are monitored. Such variables may include the rate at which the interconnected machines are played. The casino is therefore able to determine whether or not there is a relatively high level of demand for play or a relatively low level, the rate is relatively low. The casino's income, of course. increases with the rate of play.

Another variable comprises the time that the interconnected machines are played. The time variable may relate to a specific time of the day, the week, or the year. Each of these time periods includes portions in which play typically occurs at a high rate, evenings, Friday and Saturday nights, and three day weekends. and other portions in which play typically occurs at a low rate. The time variable may also relate to the length of time a particular configuration parameter has been implemented.

Still another such variable comprises the status of a player of one of the machines. The status of the player may comprise whether the player is recognized by a player-tracking system operated on the network. In the present embodiment of the invention this feature is implemented with player-tracking card 1 066 and card reader 1060. Another aspect of the player status relates to the level of player play. One aspect of the level of player play includes the rate of play both the current rate as well as the rate over a selected time period.

Next, a predetermined criterion is established for one of the monitored variables.

For example, in connection with the player status, the predetermined criterion may comprise a predetermined level of player play. establishing a predetermined rate of player play. Another predetermined criterion relates to the level of money wagered on the entire system shown in FIG. 35, which is calculated by accounting system 1038. This criterion could comprise the rate of money wagered on the entire system, as opposed to the criterion set forth above relating to the rate at which a single player wagers.

Another predetermined criterion may relate to the time. As noted above this could be the time that a particular configuration parameter has been implemented or could relate to the time of a day. week, or year.

After the predetermined criterion for one of the monitored variables is established, play is permitted to occur at the machines. When the monitored variable meets the criterion, one or more of the machines, or all, in FIG. 35 is selected, and a computer command is issued. In response to the computer command, a configuration parameter of the selected machine or machines is changed responsive to a command over the network.

Attention is now directed to FIG. 37 wherein indicated generally at 1068 is flow chart of a computer program implementing a portion of a preferred embodiment of the present invention. Computer program 1068 is implemented in software installed on configuration workstation 1040 in FIG. 35. First, a criterion is established in box 1070. As discussed above, the criterion may relate to the rate at which the interconnected machines are played, the time the interconnected machines are played, or the status of a player of one of the machines. Next, a first configuration parameter is implemented in box 1072. As discussed above, configuration parameters are implemented by installing a PROM provided by the EGM manufacturer, by generating inputs to the EGM when placed in the configuration mode, or by downloading configuration data delivered over the network of FIG. 35 to the EGM, or by a combination of the foregoing. Typically there is an initial configuration implemented via PROM or placing the EGM into a configuration mode. Implementation of initial configuration parameters, however, may be accomplished in any manner in accordance with the present invention.

In box 1074, variables such as rate at which the machines are played, time that the machines are played, and the status of players, are monitored using the network of FIG. 35. In step 1076 the program compares the monitored variables with the criterion established in block 1070. If it is not met, the program maintains the first configuration parameter implemented in step 1072 and continues to monitor variables in 1074.

When step 1076 determines that the criterion is met, a second configuration parameter is implemented in box 1078. Thereafter the program monitors system variables in box 1074 and so long as the criterion is met, maintains implementation of the second configuration parameter. When and if the criterion is not met, step 1076 directs that the first configuration parameter be again implemented in box 1072 with continued monitoring and comparison as before.

Considering now FIGS. 38 and 39, additional description will be made of examples of configuring electronic gaming machines in accordance with the present invention in which the predetermined criterion comprises the time that the interconnected machines are played and the changed configuration parameter comprises payback percentage.

-77- In a first example, illustrated schematically in FIG. 38. the time that the interconnected machines are played relates to the time of an exemplary week.

A time line 1080 is bisected by long vertical lines, like lines 1082, 1084, which define a single 24 hour day. Each day of the week beginning with Monday and ending with Sunday, is identified on the time line. Each day is bisected by three short vertical lines, like line 1086, that are equally spaced between long lines, like lines 1082, 1084. The distance from one short line to the next adjacent line therefore represents a 6 hour period. In the portion of time line 1080 representing Monday, the short line corresponding to 6:00 pm is identified with a 1, as are the portions of the time line representing Tuesday and Wednesday.

In the portion of the time line representing Tuesday, the time corresponding to 2:00 am is designated with a 2. This is also the case for Wednesday and Thursday.

Friday, Saturday, and Sunday similarly include times corresponding to numerals 1 or 2 as depicted.

In the example of FIG. 38, the time period defined between each number 1 and the following number 2 is referred to herein as a first time period. The time period between each number 2 and the following number 1 is referred to herein as a second time period. In this example, play on the machines is typically at a high level during the first time period and typically at a low level during the second time period. During the hours of the day, especially weekdays between around breakfast and midafternoon, play in some casinos is typically at a lower level than in the evening beginning around 6:00 pm. Similarly, play on the weekends during the day is at higher level than during weekdays.

The hours of the day defining the first and second periods in FIG. 38 are entered into configuration workstation 1040. A computer command is issued at the start of each period. In response to the command, a payback percentage for one, or more, of the EGMs is implemented. In accordance with the present invention, this payback percentage may be implemented by delivering over the network to each affected machine a code that is stored in a memory associated with the machine and that changes the pay table of the machine. Because some jurisdictions would not permit changing the pay table on the machine, there is an alternative way to change the payback percentage to a selected machine or machines.

Using the alternative way, the network tracks the amount ot money played on a selected gaming machine or machines that will have different payback percentages implemented. Responsive to the first command, a predetermined percentage ot the money played on the selected machines is allocated to a bonus pool that is also tracked by the network. A bonus period is also initiated responsive to the first command. During the first period a bonus is paid to the machine or machines on which the first payback percentage is implemented.

Such a bonus may be randomly awarded to one of these machines or may comprise an additional payment each time an EGM jackpot is paid in accordance with the first table. Such bonuses and the manner of implementing are described in the first embodiment. After play occurs on the machines, a second computer command is issued at the start of the second period. The second payback percentage for the selected machine or machines is implemented responsive to the second command. In this example, implementation of the second period is equivalent to turning the bonus off, i.e., money is no longer allocated to a bonus period during the second period and bonuses are not paid from the pool.

It can be seen that multiple criteria can be monitored. For example, at all times it might be desirable to provide a higher payback percentage to a player who uses a player-tracking card issued to him or her by the casino. For example, the bonus pool could always be accruing, and paying bonuses to each player using a valid player's card. Such a player would be eligible for still a higher level of bonus, additional percentage would accrue from all amounts wagered during the first period on the time line. Multiple and overlapping bonus pools could therefore be simultaneously accruing a percentage of wagers. and awarding -79 bonuses from such pools, depending upon the rate of machine play, players status, and the time the interconnected machines are played.

Turning now to FIG. 39, a second time line defines a year. With certain holidays, for example Memorial Day and Labor Day, play is typically high at all times throughout the three day weekend, with each day being represented by a vertical line in FIG. 39. The appropriate computer in FIG. 35 is therefore programmed to either override or alter the amount of the payback percentage change in the first and second periods of FIG. 38 during those weekends. In the example of FIG. 39, the period between December 25th and December 31st is traditionally a very slow time in some casinos so that the payback percentage could be correspondingly altered by either changing the amounts that would normally occur as a result of the parameters in FIG. 38 or substituting a different single one or multiple parameters for that period. It is to be appreciated that multiple variables may be monitored and multiple configuration parameters may be changed in response to the monitored variables.

Another configuration parameter comprises game speed. With respect to an electronic slot machine, the game speed is the time it takes from start of reel rotation until the reels stop spinning. With respect to electronic poker, the time relates to how fast the cards are "dealt," how rapidly they appear on the video monitor display. As discussed above, game speed, along with payback percentage and accrual of wagers in a bonus pool influence the net cost to the player per unit time for playing the casino games. Game speed is therefore one of the configuration parameters that may be changed in response to commands issued over the computer network in response to a predetermined criterion for one of the monitored variables. As with each of the other configurable parameters, an appropriate code input to the EGM serial port 1054, delivered over the network and MCI 1050, is used to change the game speed of the selected EGM.

80 Consideration will now be given to the operation of EGM 1012 in stand-alone mode, without being connected to a network via connection 1022. Initial configuration parameters are implemented as described above, either via installing PROM, by casino configuration, or by a combination of the two. In this embodiment, the RAM in MCI 1050 is programmed to monitor variables related to play on the gaming machine, such as coin in, coin out, player status, time that machine is played, etc. The MCI also allocates a predetermined percentage of the money played on the gaming machine to a bonus pool. A predetermined criterion for one of the variables is stored in the MCI RAM. The MCI compares the monitored variable to the criterion and initiates a bonus period when the criterion is met. During the bonus period, the machine pays both from the pay table and from the bonus pool based on bonus rules that are stored in the MCI and implemented via communication with EGM processor 1052. The bonus rules could provide for numerous types of payments via the EGM. The bonus could pay, for example, a specified amount from the pool in response to certain winning, or nonwinning, reel combinations. It could pay a multiple of any jackpot awarded by the EGM, or it could pay on a random basis. Numerous other rules could be established for paying from the bonus pool during a bonus period. As described above in connection with the networked implementation of the invention, this raises the payback percentage to a player of the gaming machine.

Having illustrated and described the principles of the invention in a preferred embodiment thereof, it should be readily apparent to those skilled in the art that the invention can be modified in arrangement and detail without departing from such principles. Modifications and variations such as would be apparent to a skilled addressee are deemed to be within the scope of the present invention.

For example, although an Ethernet network was described in the preferred embodiment of the invention, other high-speed networks such as wireless networks could be used in place thereof.

Throughout this specification, unless the context requires otherwise, the word "comprise", or variations such as "comprises" or "comprising", will be understood -81to imply the inclusion of a stated integer or group of integers but not the exclusion of any other integer or group of integers.
