Definitions

  • “Candles” are the electric lights placed on top of slot machines in gambling establishments to inform potential players of each machine's particular denomination and to indicate “tilts” or error states by illuminating (or flashing) certain colors.
  • candles are required on slot machines and other kinds of game devices that the particular jurisdiction classifies as slot machines.
  • the color scheme and the flashing scheme for lights on the candle both vary by jurisdiction. For example, in one area, the bottom light flashes to indicate a jackpot. In another area, both the top and bottom flash for jackpots but the bottom flashes to indicate a door open.
  • an illuminated top candle indicates a request for money change or a tilt and an illuminated bottom candle indicates a door open situation, while both candles flashing indicate a won jackpot.
  • a typical color scheme for the bottom candle colors denoting the denomination of betting coinage or currency accepted by the machine is:
  • a candle typically flashes to alert casino personnel of either a big winner or a problem with the machine.
  • the illuminated candle allows casino personnel to easily identify an unattended machine in need of service, even in a room full of hundreds of machines.
  • U.S. Pat. No. 7,014,563 to Stephan et al., entitled, “Gaming machine candle device” describes an improved candle that uses colored and transparent plastic plates in conjunction with light emitting diodes (LEDs) to more visibly and aesthetically inform patrons.
  • a first transparent colored plate is illuminated to signify the machine's denomination.
  • a second plate behind the first plate is used to inform gaming machine operators of concerns with the machine or the player.
  • the second plate may also display words or logos affiliated with operators, manufacturers or the like. Frosting and beveling techniques along edges and surfaces of the plates cause the LED light to refract highlighting those areas.
  • a transparent second plate permits the color of the first plate to be viewed throughout a gaming establishment.
  • table games in the gaming industry conventionally have static signage posted that displays a game title and minimum/maximum bet information.
  • Some electronic signage has also emerged in gaming establishments.
  • the electronic signage typically displays “canned” or predetermined looped graphics.
  • Some intelligent table game signage has also emerged that communicates with the gaming device, displaying some “real-time” graphics. Such displays generally show rudimentary information.
  • live table games which use playing cards.
  • Exemplary live table games include blackjack, poker, baccarat, and others.
  • the use of playing cards has a number of associated limitations and disadvantages which have long plagued the casino industry. Some of these are of general concern to all or most playing card games. Others are problems associated with the use of playing cards in particular games. Some of the principal concerns and problems are discussed below.
  • a dealer In the collecting operation, a dealer typically collects the cards just played at the end of a hand of play. This is done in preparation for playing the next hand of cards. The cards are best collected so all are in a face-down or face-up condition. The cards also are typically straightened into a stack with the long sides and short sides aligned. These manipulations take time and are not typically appreciated by either the dealer or players as enhancing the play and entertainment value of the game.
  • the cards collected at the end of the hand are deposited in a discard rock which collects the played cards until the time a new stack is obtained or the stack is shuffled. In some games the cards are immediately shuffled into the stock either manually or using a shuffling machine. More typically, the cards are collected and then shuffling is performed later by the dealer.
  • shuffling When shuffling is needed, it involves a break in the action of the table game and consumes a significant amount of time. Shuffling is also the most time consuming operation in preparing for the next hand. Thus, shuffling is of substantial financial significance to the casino industry because it requires significant time and reduces the number of hands which can be played per hour or other period of time.
  • the earnings of casinos is primarily dependent upon the total number of hands played. This is true because the casino on average wins a certain percent of the amounts wagered, and many or most casinos are open on a 24-hour basis. Thus, earnings are limited by the number of hands that can be played per hour. In light of this there has been a significant and keen interest by casino owners to develop practices which allow more games to be played in a given amount of time. Accomplishing this without detracting from the players enjoyment and desire to play the game is a challenging and longstanding issue with casino owners and consultants in the gaming industry.
  • Shuffling machines currently available have costs in the thousands of dollars. Such machines save time in performing the shuffling process, but still require time to load, operate and unload. These factors reduce the savings associated with reduced shuffling time and effort. Further reductions in the costs and time associated with shuffling of cards is still desired.
  • Casinos have recognized that their efforts to reduce cheating would be improved if the casino had comprehensive information on the cards which have been played, the amounts bet, the players and dealers involved and other information about actions which have taken place at the card tables. This is of particular importance in assessing the use of stacked decks. It is also important where card tracking is occurring. Additional explanation about card tracking is discussed below.
  • the information desired by the casinos includes knowing the sequence and exact cards being dealt.
  • Card shoes having card detection capability.
  • Card shoes hold a stack of cards containing typically from one to six decks of cards. The cards are held in the card shoe in preparation for dealing and to secure the deck within a device which restricts access to the cards and helps prevent card manipulations.
  • Card shoes can be fit with optical or magnetic sensors which detect the cards as they are being dealt.
  • card shoes One advantage of such card shoes is that the card sequence information can be collected in a machine readable format by sensing the specific nature (suit and count) of each card as they are dealt out of the card shoe.
  • most such card shoes have special requirements for the cards being used.
  • Such cards must carry magnetic coding or are specifically adapted for optical reading. This increases the cost of the cards and may not fully resolve the problems and difficulties in obtaining accurate information concerning sequence information.
  • the automated data collecting card shoes also do not have an inherent means for collecting data on the assignment of the card to a particular player or the dealer. They further do not collect data on the amounts bet. These factors thus require some other manual or partially automated data collection system to be used, or require that time-consuming human analysis be performed using video tapes as explained above.
  • Card tracking can be thought of as being of two types. Sequential card tracking involves determination of the specific ordering of the card deck or decks being dealt. This can be determined or closely estimated for runs of cards, sequences of cards forming a portion or portions of a stack. Sequential card tracking can be devastating to a casino since a player taking advantage of such information can bet large in a winning situation and change the odds in favor of the player and against the casino.
  • Slug tracking involves determining runs of the deck or stack which show a higher frequency of certain important cards. For example, in the play of blackjack there are a relatively large number of 10-count cards. These 10-count cards are significant in producing winning blackjack hands or 20-count hands which are also frequently winning hands. Gamblers who are proficient in tracking slugs containing large numbers of 10-count cards can gain an advantage over the house and win in blackjack.
  • the dealer cheats in collaboration with an accomplice-player.
  • This cheating is frequently accomplished when the dealer signals the accomplice using eye movements, hand movements or other signals. If a dealer does not peek, then he does not know the value of his hand until after the players have completed their play. If the dealer does peek, then he can use such eye movements, hand movements or other techniques to convey instructions to his accomplice-player. These signals tell the accomplice what hand the dealer has been dealt. With this knowledge of the dealer's hand, the accomplice has improved odds of winning and this can be sufficient to turn the long-term odds in favor of the accomplice-player and against the casino.
  • a further problem associated with live table card games are the costs associated with purchasing, handling and disposal of paper and plastic playing cards.
  • Casinos pay relatively favorable prices for card decks, but the decks roughly cost about $1-2 per deck.
  • Each casino uses decks for a very limited period of time, typically only one shift, and almost always less than one day. After this relatively brief life in the limelight, the decks are disposed of in a suitable manner. In some cases they can be sold as souvenirs. This is done after the cards are specially marked or portions are punched out to show they have been decommissioned from a casino. This special marking allows the cards to be sold as souvenirs while reducing the risk that they will later be used at the card tables in a cheating scheme which involves slipping a winning card into play at an appropriate point. In other cases the playing cards are simply destroyed or recycled to eliminate this last risk. In any case, the cost of playing cards for a casino is significant and can easily run in the hundreds of thousands of dollars per year.
  • Intelligent candle displays for electronic game machines are described.
  • an electric signaling candle for game machines used in gambling establishments is communicatively coupled via a controller with one or more display screens for showing image and video graphics.
  • the candle and the display screen(s) may be physically combined into one unit, or physically separated but communicatively coupled to present integrated and harmonized information and visual effects.
  • the intelligent candle display can interact in real time with the game machine hardware and with the action of a game being played in order to display relevant real time action and information.
  • the intelligent candle display serves multiple simultaneous purposes, such as informing casino management of jackpots and machine problems, providing betting information to players, interacting with the game players, advertising, and acquainting and welcoming bystanders to the game machine.

Such dealing involves generating random numbers which are used in selecting from the available cards contained in the set of cards defined to be the card stock. It further involves displaying the cards which have been dealt upon the displays in the manner and with the appearance described above, or some other suitable manner and appearance. Additional description of the two card dealing operation will be described below in connection with FIG. 28 .

  • the next step illustrated in FIG. 26 is a step of identifying players having a blackjack hand after the dealing of the two initial cards to each participating player station and to the dealer station (all participants).
  • the following step 224 includes considering the next active player and analyzing the hand which is held by such player. After the analyzing the hand, there is a process of applying the basic strategy rules to the analyzed player hand to perform a deriving of basic strategy suggestion. This basic strategy suggestion is then implemented by displaying the basic strategy as step 227 , such as in a manner explained above in connection with the player display descriptions.
  • FIG. 26 also shows some alternative playing options which are considered in the course of the data processing functions.
  • Step 230 provides a surrender option which may be made available to the player by presenting some indication of surrendering, or by merely allowing the player to orally or otherwise indicate he or she is surrendering after the initial two cards have been dealt and as an initial play decision associated with the hand the player has received versus the knowledge the player has of what the dealer has been dealt.
  • One possible playing rule in this regard might be to allow the player to surrender, in which case the player would lose at that point one-half of his bet. This might be done in case the dealer appeared to have a blackjack hand and the player did not have a blackjack hand and did not believe he was likely to achieve a winning hand by receiving one or more hit cards.
  • step 233 occurs which involves deactivating the surrendering player. The process can then be continued with regard to additional players who would either opt for surrendering or not surrendering.
  • FIG. 26 also shows a step 239 which involves analyzing to determine if the dealer has been dealt an ace as his upcard. If so, then the game can advantageously perform by presenting the players with a notice, such as by displaying a message concerning insurance on the player or dealer displays. Although such a message is not shown in the figures, a simple flashing “INSURANCE?” might be used on either or both displays and then waiting sufficient time for the player to place their insurance bets upon the insurance bet detection zones 130 . The game processor can then perform by detecting the presence of any insurance bets and logging such information into the game files being created in the game processor memory. If the dealer does not have a blackjack hand, then the step 242 of collecting the insurance bets can be performed by the dealer.

  • FIG. 26 further shows a step 245 which entails considering whether any player desires to split his or her hand.
  • the split option typically occurs when the player has received two cards of similar kind, such as two kings or two aces.
  • the player in particular may want to split on two aces since each has a relatively high probability of getting a ten-count card to make blackjacks. This is in comparison to valuing each of the aces as either 1 or 11 and further playing the cards as a single hand.
  • Step 248 represents implementing the active split hands and dealing an additional card to the split hand to provide two cards.
  • the first split hand is then played out and play continues on to the second or subsequent split hand of the same player.
  • FIG. 26 further includes a step 254 which performs by considering whether any players want to make a double down play. If so, then they indicate such to the dealer who depresses control key 86 ( FIG. 5 ) and step 257 occurs which involves dealing the additional double down card to that player. The system then performs by evaluating the player's hand in step 263 .

  • the dealer follows through by depressing either the stand or hit control keys 87 and 88 , respectively.
  • step 266 is performed and the game processor performs by analyzing the player's hand to determine whether the player has busted. If not, then the player is given another opportunity to obtain a hit card and the process repeats until the player elects to stand. In the last case the processor performs in step 263 by evaluating the final hand count and hand composition and then proceeds to address the additional participating players. If the player busts, then step 269 is performed in which case the dealer proceeds to the next available participating player or proceeds to step 271 .
  • step 271 the process continues by playing out the dealer's hand. This may involve hitting or standing in a manner similar to play by the players as explained above.
  • Step 274 is performed by determining which players have won or lost, and then such information is displayed on the displays 103 , or 102 , such as described hereinabove.
  • FIG. 27 shows additional detail not depicted in FIG. 26 in the form of a main loop routine to further clarify processes used leading up to the dealing of the initial two cards.
  • Steps 206 and 207 are as explained above.
  • Step 283 involves testing for the edit rules security lock having been opened by the appropriate code key. If so, then the edit rules subroutine 208 is performed. If not, then various buffers and arrays are prepared for normal operation in an initiating step 292 . This will involve loading programming from read only memory or other programming source to set up the game processor for operation.
  • Step 295 involves displaying any casino names or logos or otherwise displaying an attraction display image, such as upon the player displays 102 , dealer display 103 , or shoe displays 81 or 82 . Thereafter, the game processor performs in step 298 by looking for any wagers as indicated by sensors 121 .

  • the cut card can then be specially displayed, such as by using a highlighting color.
  • Such a process can also involve progressively moving the cut card as virtual cards are dealt.
  • An alternative cutting operation can be performed similar to the cutting just described but it is instead performed by the dealer touching display 81 rather than the player. This can be done in response to the dealer's judgment, or more preferably, the dealer can undertake such action in response to instructions from one of the players.
  • a still further alternative approach in performing a stack cutting operation is to have a selected player perform by instructing the dealer.
  • the dealer in this alternative would be empowered to move a virtual cut card as it appears on the display.

  • the dealer could then perform by moving or repositioning the cut card position within the stack by using one or more of the dealer control keys 85 - 89 which would become soft keys assigned to this repositioning function.
  • the player performing the cutting judgment would then act by instructing the dealer as to the desired position of the cut card and the dealer would perform this repositioning as displayed on the display.
  • the repositioning could be affected by adjusting the cut card position as needed in response to the instructions given by the player who is empowered with the cutting operation.

  • Step 322 of FIG. 28 illustrates the moving card routine advantageously performed by the second shoe display 82 in order to add realism to the game.
  • Such a step includes indicating motion of playing card images after the dealer has commanded that dealing begin using touch key 89 . This can advantageously be performed using the second shoe display 82 .
  • the motion indicating step can be done by shifting the apparent card back face image downwardly within the second shoe display and thus visually indicating that the dealing process is being performed. This can be of added realistic effect and aid the players in easily recognizing the action of the blackjack or other card game being played.
  • Step 322 is followed by adjusting the simulated stack display in the first shoe display 81 by shifting the position of the cut card and moving it closer to the second display.
  • FIG. 28 also shows step 328 which involves selecting a card from the stack using the random number generator.
  • the shuffling processes used in the system can be performed in three processes.
  • a first shuffling process herein called traditional shuffling
  • the random number generator is used to create an assigned order to all cards of the stock prior to dealing any card to any participant in the game. This is akin to the manner in which the real paper or plastic playing cards are handled in real playing card mode, since the decks comprising the stack are shuffled and reshuffled the desired number of times to reorder the stack.
  • any desired cutting of the deck is performed and the stock is placed into a dealing shoe. Once placed into a dealing shoe the order of the cards is fixed and no reordering occurs.
  • shuffling is made available using system 60 which is usually not available when using real paper or plastic physical playing cards.
  • This shuffling process is herein termed continuous random shuffle.
  • the order of distribution of cards from the stock is not predetermined before the hand is played. Instead the random number generator operates on the fly as needed when the game requires a card to be taken from the stack.
  • the position from the stack is varied to produce the random distribution of potentially any card at any time.
  • the entire set of virtual cards which make up the stack is maintained at all times, without removing cards which may already have been dealt in the same playing hand. This maintaining a set of all available cards in the stack achieves truer randomness than by reducing the stack set for removed cards. In any particular card assignment, the player can receive any of the possible cards. This procedure may be desirable in play of certain games or may be more attractive to the casino or players for objective or subjective reasons which become important.
  • random balance shuffling Another shuffling or card assignment process which is contemplated by this invention is herein termed random balance shuffling.
  • random balance shuffling the set of available cards in the virtual stack is reduced by the assignment of prior cards dealt in the hand. For example, where the first card dealt is an ace of spades, and the stack is defined by the casino to be only one deck, then no other player in that hand can receive the ace of spades. In most casinos blackjack is played using stacks where there are multiple decks, for example six decks. In such situations, then there clearly would be additional aces of spades which might be dealt. However, the frequency of selecting the ace of spades after one or more other aces of spades have been already dealt in that hand does diminish. This should be contrasted to the continuous random shuffle wherein the expected statistical frequency does not change as cards are dealt.
  • Step 328 schematically represents the selection of the next card whether this is done on the fly using continuous random shuffle, or random balance shuffle. Alternatively, the selection process can be done with pre-ordering using the traditional shuffle.
  • the traditional shuffle does have a significant disadvantage which blackjack players may have noticed or experienced. This disadvantage is demonstrated by the situation where one player either stands or hits in a nonconventional manner, either by mistake or intent. Other players at the table often notice this apparent error, and as a result the next player or dealer would receive a different card than if the prior player had played his hand in a conventional manner. In some cases, the difference in cards can affect some or all who receive cards thereafter. In some cases, players become irate because of the realization that this mistaken choice by another player has cost the other players their bets and the wins which they otherwise would have enjoyed. This type of situation can be very upsetting and sometimes even leads to fights among the players.
  • step 334 effects the displaying of the card on the player's display if it is a card assigned to a player.
  • the game system also effects displaying a copy of the player's card on all screens when appropriate as explained above in connection with the player display images.
  • the game then involves assessing whether the next action is with a player or dealer in step 340 . This process repeats until all players have received their first card. Then a virtual card is assigned to the dealer in step 343 .
  • the first card to the dealer is dealt as a face-down card and is often referred to as the hole card.
  • Step 350 indicates that the hole card of the dealer is dealt and displayed facedown.
  • the process explained above repeats again for the active players and dealer until step 347 indicates that a second card has been received by the dealer.
  • process 221 proceeds to determine the players with blackjack hands.
  • FIG. 29 details the process, shown abbreviated as step 221 in FIG. 26 , for determining players with blackjack hands.
  • Step 362 involves going on to the next active player for consideration.
  • Step 365 is evaluating the player's hand.
  • Step 369 is whether a blackjack hand is present. Step 369 leads to repeating steps 362 and 365 for another player if no blackjack hand is present. If a blackjack hand is present, then the process branches to step 372 wherein the program functions by identifying the player or players with a blackjack hand by player number “n”.
  • Step 375 performs a decision whether the player, more properly participant, is a player or the dealer. If the answer is yes indicating it is the dealer, then the game is over and the two card play sequence is then repeated in another hand. If the blackjack hand is not for the dealer, then the player's status is changed by step 381 to changing the status to inactive with regard to additional play of the hand.
  • FIG. 30 details a two card play sequence 387 which is shown in abbreviated form in FIG. 26 .
  • Step 224 includes going to the next active player. Thereafter the processor performs in step 393 by displaying the active hand on all player displays, in the tertiary part of the display as explained above.
  • Step 396 involves displaying the dealer's hand to all displays.
  • Step 399 involves calling up the strategy analysis monitor and performing such strategy analysis to provide a basic strategy note to be displayed to the active player.
  • the step 227 of displaying the basic strategy on the active player's display is then included, thereby rendering helpful advice to the player.
  • FIG. 30 shows more complete steps in assessing surrender.
  • Step 405 involves checking the game rules to see if the casino allows surrender as a play option. If yes, then decision step 408 proceeds to branch to an instructing step for allowing surrender by a player or players in step 411 .
  • Step 414 indicates the player's individual decisions whether to surrender. If decision 414 is yes, then that player is rendered into inactive status by an inactivating step 417 . This process is repeated via connection A for other players. If surrender is not selected, then step 420 provides for evaluating the dealer's upcard. If the dealer's upcard is an ace, then decision step 239 branches to an insurance sequence detailed in FIG. 31 . Return occurs in returning from insurance sequence at step 429 .
  • the game processor performs by assessing whether the player's hand has a pair in steps 432 and 435 . If no pair exists, then the process continues by proceeding on with the consideration of whether the player wants to double down as shown in step 254 of FIG. 26 . If there is a pair, then a split sequence branch step 441 is performed as detailed in FIG. 32 .
  • An insurance sequence shown in FIG. 31 branches from decision step 239 of FIG. 30 and advances to step 447 which involves going to the next active player.
  • the possibility for taking insurance is publicized by notifying the players using a displaying step 450 which notes such on all displays 102 and 103 .
  • Step 453 then involves detecting whether insurance bets have been made. This is repeated by deciding in step 456 whether additional active players have taken insurance bets and the logical loop is again cycled until there are no more players and the process returns via branch 429 to the two card play sequence shown in FIG. 30 .
  • FIG. 32 details the split hands process sequence 441 from step 435 of FIG. 30 .
  • the player decides whether to split his hand at step 465 and this is implemented by the dealer depressing key 85 to indicate the hand should be split by the game processor. If the hand is not split, then processing goes on to the additional two card play sequence of FIG. 33 at step 504 . If the player elects to split by accepting the split offer, then step 468 is processed and a split counter is incremented. Thereafter in step 471 the processor processes data to split the original hand containing the pairs into two hands. Step 474 performs by identifying that each of the split hands has only one card.
  • Step 477 performs by instructing that an additional card should be dealt.
  • Step 480 performs by copying the instruction to deal cards to the split hands.
  • Step 483 involves dealing the additional cards.
  • Step 486 performs by deciding whether there are additional split opportunities which have developed from the newly dealt cards. If so, then step 489 performs by incrementing the split counter.
  • Decision step 492 compares the split counter to make sure the maximum allowable splits programmed by the casino rules has not been exceeded. If not, then recycling through step 468 and the splitting function repeats. If there are no further split options from decision step 486 , then processing continues on to step 504 of FIG. 33 .
  • FIG. 33 shows an additional two card play sequence which includes a step 504 which involves calling the strategy monitor to apply the strategy rules to the player's hand after the splitting or insurance subroutines have been completed.
  • the next step 507 involves displaying the suggested strategy.
  • the players place an additional bet to “double down” in step 510 .
  • Decision step 254 responds to a yes with a doubling of the wager in the processor at step 516 .
  • Step 519 is dealing of the additional single double down card.
  • Step 522 involves evaluating the player's hand after the double down card has been assigned.
  • Decision step 525 involves determining whether the resultant player hand has busted. If yes, then step 528 involves displaying the bust outcome. If no, then a revised hand total results and this is performed by communicating or displaying the new hand total in step 531 .
  • FIG. 33 also shows that if the player does not double down in decision step 254 , then step 534 results. Thereafter the action is for the player to proceed by indicating whether he or she wants to be hit with another card or stand. If the decision in step 540 is to hit, then dealing of another card occurs as shown in step 543 . The player's hand is then acted upon by the game processor performing an evaluating step 546 to proceed on with a decision step 549 whether the hand has busted. If not, then the hit/stand option is again considered by the player and the portion of the sequence is repeated until either there is a bust or a stand decision. If there is a bust, then step 552 involves displaying the bust as described above. If the decision is to stand as represented by standing step 555 , then processing continues on to step 558 looking for more active players.

Abstract

Intelligent candle displays for electronic game machines are described. In one implementation, an electric signaling candle for game machines used in gambling establishments is communicatively coupled via a controller with one or more display screens for showing image and video graphics. The candle and the display screen(s) may be physically combined into one unit, or physically separated but communicatively coupled to present integrated and harmonized information and visual effects. The intelligent candle display can interact in real time with the game machine hardware and with the action of a game being played in order to display relevant real time action and information. The intelligent candle display serves multiple simultaneous purposes, such as informing casino management of jackpots and machine problems, providing betting information to players, interacting with the game players, advertising, and acquainting and welcoming bystanders to the game machine.

  • This continuation-in-part application claims priority to co-pending U.S. patent application Ser. No. 11/404,955 to Sines et al., entitled, “Multi-player electronic display gaming apparatuses,” filed Apr. 14, 2006 and incorporated herein by reference, which in turn was a continuation of U.S. Pat. No. 7,255,642, which was a continuation of U.S. Pat. No. 6,651,985, which was a continuation of U.S. patent application Ser. No. 09/159,813 (abandoned), which was a continuation-in-part of U.S. Pat. No. 6,165,069, filed Mar. 11, 1998. This application also claims priority to U.S. Provisional Patent Application No. 61/115,550 to Kuhn, entitled “Intelligent Candle Display for Game Machines,” filed Nov. 18, 2008.
  • BACKGROUND
  • “Candles” are the electric lights placed on top of slot machines in gambling establishments to inform potential players of each machine's particular denomination and to indicate “tilts” or error states by illuminating (or flashing) certain colors. In some legal jurisdictions, candles are required on slot machines and other kinds of game devices that the particular jurisdiction classifies as slot machines. The color scheme and the flashing scheme for lights on the candle both vary by jurisdiction. For example, in one area, the bottom light flashes to indicate a jackpot. In another area, both the top and bottom flash for jackpots but the bottom flashes to indicate a door open. In one scenario, an illuminated top candle indicates a request for money change or a tilt and an illuminated bottom candle indicates a door open situation, while both candles flashing indicate a won jackpot. Although not universal, a typical color scheme for the bottom candle colors denoting the denomination of betting coinage or currency accepted by the machine is:
  • Brown=penny machine
  • Pink/Red=nickel machine
  • Yellow=quarter machine
  • Orange=fifty-cent machine
  • Blue=dollar machine
  • A candle typically flashes to alert casino personnel of either a big winner or a problem with the machine. The illuminated candle allows casino personnel to easily identify an unattended machine in need of service, even in a room full of hundreds of machines.
  • U.S. Pat. No. 7,014,563 to Stephan et al., entitled, “Gaming machine candle device” describes an improved candle that uses colored and transparent plastic plates in conjunction with light emitting diodes (LEDs) to more visibly and aesthetically inform patrons. A first transparent colored plate is illuminated to signify the machine's denomination. A second plate behind the first plate is used to inform gaming machine operators of concerns with the machine or the player. The second plate may also display words or logos affiliated with operators, manufacturers or the like. Frosting and beveling techniques along edges and surfaces of the plates cause the LED light to refract highlighting those areas. A transparent second plate permits the color of the first plate to be viewed throughout a gaming establishment.
  • In contrast to the color-code and flashing light signal schemes of candles, table games in the gaming industry conventionally have static signage posted that displays a game title and minimum/maximum bet information. Some electronic signage has also emerged in gaming establishments. The electronic signage typically displays “canned” or predetermined looped graphics. Some intelligent table game signage has also emerged that communicates with the gaming device, displaying some “real-time” graphics. Such displays generally show rudimentary information.
  • Additional Background on Electronic Table Games
  • In the gaming industry there is a significant volume of gambling which occurs at live table games which use playing cards. Exemplary live table games include blackjack, poker, baccarat, and others. There is also a number of proprietary or specialty live table card games which have developed, such as Pai-Gow poker, LET-IT-RIDE, CARIBBEAN STUD, and others. These and many other games all involve play using playing cards. The use of playing cards has a number of associated limitations and disadvantages which have long plagued the casino industry. Some of these are of general concern to all or most playing card games. Others are problems associated with the use of playing cards in particular games. Some of the principal concerns and problems are discussed below.
  • The use of playing cards at live table games typically involves several operational requirements which are time-consuming. These operations are conveniently described as collecting, shuffling and dealing of the cards. In many card games there is also a step of cutting the deck after it has been shuffled.
  • In the collecting operation, a dealer typically collects the cards just played at the end of a hand of play. This is done in preparation for playing the next hand of cards. The cards are best collected so all are in a face-down or face-up condition. The cards also are typically straightened into a stack with the long sides and short sides aligned. These manipulations take time and are not typically appreciated by either the dealer or players as enhancing the play and entertainment value of the game.
  • In many games the cards collected at the end of the hand are deposited in a discard rock which collects the played cards until the time a new stack is obtained or the stack is shuffled. In some games the cards are immediately shuffled into the stock either manually or using a shuffling machine. More typically, the cards are collected and then shuffling is performed later by the dealer.
  • When shuffling is needed, it involves a break in the action of the table game and consumes a significant amount of time. Shuffling is also the most time consuming operation in preparing for the next hand. Thus, shuffling is of substantial financial significance to the casino industry because it requires significant time and reduces the number of hands which can be played per hour or other period of time. The earnings of casinos is primarily dependent upon the total number of hands played. This is true because the casino on average wins a certain percent of the amounts wagered, and many or most casinos are open on a 24-hour basis. Thus, earnings are limited by the number of hands that can be played per hour. In light of this there has been a significant and keen interest by casino owners to develop practices which allow more games to be played in a given amount of time. Accomplishing this without detracting from the players enjoyment and desire to play the game is a challenging and longstanding issue with casino owners and consultants in the gaming industry.
  • An additional consideration in the casino industry is the costs associated with shuffling machines. Shuffling machines currently available have costs in the thousands of dollars. Such machines save time in performing the shuffling process, but still require time to load, operate and unload. These factors reduce the savings associated with reduced shuffling time and effort. Further reductions in the costs and time associated with shuffling of cards is still desired.
  • The amount of time consumed by collecting, shuffling and dealing is also of significance in private card games because it also delays action and requires some special effort to perform. In private games there is also some added complexity due to card players remembering or figuring out who previously dealt and who should now shuffle and re-deal the cards as needed.
  • In addition to the time delay and added activity needed to collect, shuffle and deal cards, there is typically some time devoted to cutting the deck of cards which have been shuffled and which are soon to be dealt. This traditional maneuver helps to reduce the risk that the dealer who has shuffled the cards may have done so in a way that stacks the deck in an ordered fashion which may favor the dealer or someone else playing the game. Although cutting the deck does not require a large amount of time, it does take some time. The amount of time spent on cutting reduces the frequency at which hands of the card game can be played.
  • The above and related considerations clearly demonstrate that a substantial amount of time is consumed by collecting, shuffling, cutting and dealing playing cards. The casino industry has long felt the desire to reduce the time spent and increase play of live table games.
  • In the gaming industry there is also a very significant amount of time and effort devoted to security issues which relate to play of the casino games. Part of the security concerns stem from frequent attempts to cheat during play of the games. Participants may try to view each other's cards when the game involves betting and bluffing in association with a hidden combination of cards. Attempts to cheat are made not only by players, but also by dealers, and more significantly by dealers and players in collusion. This cheating seeks to affect the outcome of the game in a way which favors the dealer or players who are working together. The amount of cheating in card games is significant to the casino industry and constitutes a major security problem which has large associated losses. The costs of efforts to deter or prevent cheating are very large and made on a daily basis.
  • Many of the attempts to cheat in the play of live table card games involve some aspect of dealer manipulation of cards during collection, shuffling, cutting or dealing of cards. Thus, there is a need for methods and apparatuses which can be used in the play of live table card games which reduces the ability of the dealer and/or players to cheat by manipulation of playing cards. Of greatest concern are schemes whereby the deck is stacked and the stacked deck is used to the collusive player's advantage. Stacked decks represent huge potential losses since the player is aware of the cards which will be played before play occurs and can optimize winnings by increasing bets for winning hands and decreasing bets for losing hands.
  • Casinos have recognized that their efforts to reduce cheating would be improved if the casino had comprehensive information on the cards which have been played, the amounts bet, the players and dealers involved and other information about actions which have taken place at the card tables. This is of particular importance in assessing the use of stacked decks. It is also important where card tracking is occurring. Additional explanation about card tracking is discussed below. The information desired by the casinos includes knowing the sequence and exact cards being dealt.
  • Some attempts have been made to record card game action. The best current technology involves cameras which are mounted above the tables to record the action of the card games. This approach is disadvantaged by the fact that not all cards dealt are easily known from a camera position above the table because some or all of the cards are not dealt face-up, or are hidden by overlying cards. Although many Blackjack games are sufficiently revealing to later determine the order of dealt cards, others are not. Other card games, such as poker, have hands which are not revealed. The covered cards of the players do not allow the order of dealt cards to be ascertained from an above-table camera.
  • Even where above-table cameras are used, their use may not be effective. Such cameras may require time-consuming and tedious human analysis to go over the video tapes or other recordings of table action. This human study may be needed just to ascertain the sequence of cards dealt or to determine the amount of betting. Such human analysis is costly and cannot economically be used to routinely monitor all action in a casino cardroom. It is also required because there is no current way for easily ascertaining whether the dealer or player won the hand, such as in a blackjack game. It is typically not possible to discern the indicia number or letter presented in the corner of the playing card when viewed in a recorded video tape. Counting the individual pips in the center field of the playing cards can be done; however, it cannot be done in all situations with the desired reliability. This is true because cards may be partly or totally covered by another overlying card contained in the same hand, leading to missing information or mistaken interpretations.
  • For the above reasons, the video camera monitoring techniques have only found very limited effectiveness as a routine approach for identifying cheating. There has also been relatively limited use as a serious analytical tool because of the difficulty of analysis. Such camera surveillance techniques are also of only limited effectiveness as a deterrent because many of the people involved with cheating have a working knowledge of their limitations and utilize approaches which are not easily detectible by such systems.
  • Another use of video camera monitoring and recording has been made in the context of analyzing card table action after someone has become a suspect. The tape recordings serve as evidence to prove the cheating scheme. However, in the past, this has generally required other evidence to initially reveal the cheating so that careful analysis can be performed. More routine and general screening to detect cheating has remained a difficult and continuing problem for casinos.
  • Another approach to reducing security problems utilizes card shoes having card detection capability. Card shoes hold a stack of cards containing typically from one to six decks of cards. The cards are held in the card shoe in preparation for dealing and to secure the deck within a device which restricts access to the cards and helps prevent card manipulations. Card shoes can be fit with optical or magnetic sensors which detect the cards as they are being dealt. Some of the problems of security analysis using above-table cameras is reduced when the sequence of cards dealt can be directly determined at the card shoe using optical or magnetic sensors.
  • One advantage of such card shoes is that the card sequence information can be collected in a machine readable format by sensing the specific nature (suit and count) of each card as they are dealt out of the card shoe. However, most such card shoes have special requirements for the cards being used. Such cards must carry magnetic coding or are specifically adapted for optical reading. This increases the cost of the cards and may not fully resolve the problems and difficulties in obtaining accurate information concerning sequence information.
  • The automated data collecting card shoes also do not have an inherent means for collecting data on the assignment of the card to a particular player or the dealer. They further do not collect data on the amounts bet. These factors thus require some other manual or partially automated data collection system to be used, or require that time-consuming human analysis be performed using video tapes as explained above.
  • An additional issue which has continued to be a concern in the casino industry relates to the use of automated shuffling machines. Prior automated shuffling machines have not demonstrated a sufficient ability to thwart highly skilled gamblers. Such gamblers have demonstrated an ability either by human intellect and training, or with the aid of computers, to determine information about the decks being dealt. This information is typically derived from information collected concerning the preceding hand or hands of play. Armed with such information, the skilled gamblers track a specific sequence or multiple sequences or groupings of cards within a deck or large stock. Tracking is often done for a group of cards forming part of a stack rather than an entire stack. These techniques in card tracking can significantly shift the advantage from the casino to a skilled gambler. Prior card shuffling machines all show a weakness in that skilled gamblers can observe operation of the machines and in many situations make predictions which serve as a means for card tracking.
  • The use in blackjack of numerous card decks, such as six decks, has been one strategy directed at minimizing the risk of card tracking. Such tracking should be contrasted with card counting strategies which are typically less accurate and do not pose as substantial a risk of loss to the casino. Use of numerous card decks in a stack along with proper cut card placement can also reduce the risk of effective card counting. However, it has been found that multiple decks are not sufficient to overcome the skilled gambler's ability to track cards and turn the advantage against the house.
  • Card tracking can be thought of as being of two types. Sequential card tracking involves determination of the specific ordering of the card deck or decks being dealt. This can be determined or closely estimated for runs of cards, sequences of cards forming a portion or portions of a stack. Sequential card tracking can be devastating to a casino since a player taking advantage of such information can bet large in a winning situation and change the odds in favor of the player and against the casino.
  • Slug tracking involves determining runs of the deck or stack which show a higher frequency of certain important cards. For example, in the play of blackjack there are a relatively large number of 10-count cards. These 10-count cards are significant in producing winning blackjack hands or 20-count hands which are also frequently winning hands. Gamblers who are proficient in tracking slugs containing large numbers of 10-count cards can gain an advantage over the house and win in blackjack.
  • There is also a long-standing problem in the play of blackjack which concerns the situation when the dealer receives a blackjack hand in the initial two cards dealt. If the dealer has a 10-count card or ace as the upcard, then it is possible for the dealer to have a blackjack. If the dealer does have a blackjack, then there is no reason to play the hand out since the outcome of the hand is already determined without further dealing. If the hand is fully played out, and the dealer then reveals that the dealer has received a blackjack hand, then a significant amount of time has been wasted. It also causes players to often be upset when a hand is played out to no avail.
  • In many casinos the waste of time associated with playing out hands with a winning dealer blackjack has lead to various approaches which attempt to end the hand after the initial deal. Some of these allow the dealer to look at the down card to make a determination whether a blackjack hand has been dealt to the dealer. This looking is commonly called “peeking” and is an operation which has been the source of numerous cheating schemes involving dealers and players who work in collusion.
  • In such cheating associated with peeking at the down card, the dealer cheats in collaboration with an accomplice-player. This cheating is frequently accomplished when the dealer signals the accomplice using eye movements, hand movements or other signals. If a dealer does not peek, then he does not know the value of his hand until after the players have completed their play. If the dealer does peek, then he can use such eye movements, hand movements or other techniques to convey instructions to his accomplice-player. These signals tell the accomplice what hand the dealer has been dealt. With this knowledge of the dealer's hand, the accomplice has improved odds of winning and this can be sufficient to turn the long-term odds in favor of the accomplice-player and against the casino.
  • Because of this potential for cheating, peeking as a normal procedure in the play of blackjack has been viewed with disfavor by many casinos. Some casinos which have experienced losses due to such cheating have eliminated the peeking procedure and decided to instead incur the waste of time and problems associated with playing out the hand of cards.
  • There has also been a substantial number of apparatuses devised to facilitate the peeking procedure or render it less subject to abuse. Such peeking devices are intended to allow determination of whether the dealer has received a blackjack hand; however, this is done without revealing to the dealer what the down card is unless it makes a blackjack. Some of these devices require a special table with a peeking device installed in the table. Others allow the down card to be reviewed using a table top device in which the card is inserted. These systems and others involve the use of special playing cards. These devices and methods generally add greater costs and slow the play of the game. The slowed play often occurs to such a degree that it offsets the original purpose of saving the time associated with playing out possible dealer blackjack hands. The prior attempts have often ended up unacceptable and are removed. This problem has nagged the casino industry for many years and a fully acceptable solution has never been found.
  • Another notable problem suffered by live table games is the intimidation which many novice or less experienced players feel when playing such games. Surveys have indicated that many new or less experienced people who come to a casino are inclined to play slot machines and video card games. These people feel intimidation at a live table game because such games require quick thinking and decision making while other people are watching and waiting. This intimidation factor reduces participation in table games.
  • The intimidation factor experienced by many in connection with live table games has had a very significant effect on casinos and the games offered in the casinos. Years ago, live table games constituted approximately two-thirds of the casino business, with slot machines being the remaining one-third. Now it is just the opposite, with two-thirds of the business being in slot machines and similar single person gaming machines while live table games constitute only one-third of the business. Since betting at live table games is generally larger, this development is something of a disadvantage to the casinos as compared to the same persons participating in a live table game. Efforts to stem or reverse this trend using specialty table games with different play and larger jackpots have not been effective or of only temporary beneficial effect. Some of the efforts have produced fads or other temporary increases in interest levels but the overall effect has not had a long-term benefit. Thus, there is a need for improved live table games which reduce the intimidation factor and enhance the ease with which a player adopts play of such games. There is also need for live table games which provide satisfaction to those who play, such that repeat participation is improved.
  • A further issue which has developed in the casino business is the public's increasing interest in participating in games which have a very large potential payoff. This may be in part be a result of the large amount of publicity surrounding the state operated lotteries. News of huge payoffs is read with keen interest and creates expectations that gaming establishments should provide games with large jackpots. One approach has been the networked or progressive slot machines that use a centralized pool of funds contributed by numerous players. These slot machine systems are relatively more costly to purchase and operate. For many gamblers, this approach is not particularly attractive. This lack of attractiveness may be due to the impersonal and solitary nature of playing slot machines. It may alternatively be for other reasons. Whatever the reason, the public is clearly interested in participating in games which can offer potential jackpots which are very large. Table card games have not been able to satisfactorily address this interest. The continued diminishment in the percent of people who play live table games indicates the need for more attractive games and game systems which address to public's interests.
  • A further problem associated with live table card games are the costs associated with purchasing, handling and disposal of paper and plastic playing cards. Casinos pay relatively favorable prices for card decks, but the decks roughly cost about $1-2 per deck. Each casino uses decks for a very limited period of time, typically only one shift, and almost always less than one day. After this relatively brief life in the limelight, the decks are disposed of in a suitable manner. In some cases they can be sold as souvenirs. This is done after the cards are specially marked or portions are punched out to show they have been decommissioned from a casino. This special marking allows the cards to be sold as souvenirs while reducing the risk that they will later be used at the card tables in a cheating scheme which involves slipping a winning card into play at an appropriate point. In other cases the playing cards are simply destroyed or recycled to eliminate this last risk. In any case, the cost of playing cards for a casino is significant and can easily run in the hundreds of thousands of dollars per year.
  • In addition to the above problems, there are also a significant cost associated with handling and storing the new and worn playing cards. Sizable rooms contained in the casino complexes are needed just to store the cards as they are coming and going. Thus, the high cost of casino facilities further exacerbates the costs associated with paper and plastic playing cards.
  • These and other considerations have been partially or fully addressed by the current invention which is described more fully below. Additional benefits and advantages of the current invention will be given in the following description, or will be apparent from the nature of the invention.
  • SUMMARY
  • Intelligent candle displays for electronic game machines are described. In one implementation, an electric signaling candle for game machines used in gambling establishments is communicatively coupled via a controller with one or more display screens for showing image and video graphics. The candle and the display screen(s) may be physically combined into one unit, or physically separated but communicatively coupled to present integrated and harmonized information and visual effects. The intelligent candle display can interact in real time with the game machine hardware and with the action of a game being played in order to display relevant real time action and information. The intelligent candle display serves multiple simultaneous purposes, such as informing casino management of jackpots and machine problems, providing betting information to players, interacting with the game players, advertising, and acquainting and welcoming bystanders to the game machine.

  • DETAILED DESCRIPTION
  • Overview
  • This disclosure describes intelligent candle displays (hereinafter, “candle displays”) for game machines. In one implementation, an exemplary candle display combines a candle—the stack of indicator lights often placed atop game machines—with a display screen capable of showing text, images, and videos. In one implementation, an innovative candle display controller manages the operation and interdependence of the candle component and the display screen component of the exemplary candle display. The controller harmonizes the signaling and information display functions that each component can provide, to synergistically create a visual display that is more effective than either a candle or a display screen taken separately.
  • Electronic table games in gambling establishments are increasingly classified as multiplayer slot machines and as a result are being required by some jurisdictions to incorporate a candle. Such an electronic table game with a candle is shown and described below with respect to FIGS. 52-53, and likewise previously shown and described in related parent application, now U.S. Pat. No. 6,651,985 to Sines et al., entitled, “Automated system for playing live casino table games having tabletop changeable playing card displays and play monitoring security features.”
  • In one implementation, an exemplary candle display combines a candle, i.e., lights, for indicating a status of a game playable on the game machine and for indicating a status of the game machine, with a display screen for providing sophisticated information and graphics. The combination of candle and display may be physical and operational, merely physical, or merely operational, depending on implementation. For example, the exemplary candle display may combine physically separate candle and display screen components by enabling the candle and the display screen under common direction to each participate in a common display task. For example, when the candle flashes to announce a jackpot winner, the a physically separate display screen may alternate flashing a colorful graphic or message between the candle flashes—i.e., alternating flashes between the two devices.
  • In one implementation, the candle signals hardware statuses of the game machine and statuses of the game itself, including statuses of the player, e.g., as winner, or in needed of assistance. The display screen displays accompanying graphics and information. The controller manages operations of the candle(s) and the display screen(s), harmonizing and integrating their functions to provide operational interdependence. In doing so, the controller provides synergism between functions, such as the information-signaling and attention-getting functions of the candle, and the information-displaying and attention-getting functions of the display screen. Thus, the controller includes logic to perform management of both devices, for example, directing the display screen to show an attention-getting graphic and explanatory information in reinforcement of a status indicated by the candle.
  • Both the display screen and the candle can show dynamically changing information and attention-getting visuals, but in different ways. The information that can be displayed and accentuated by the combination of the two devices includes a betting denomination or a betting limit of the game machine; a jackpot total won on the game machine in conjunction with a jackpot indication displayed by the candle; an identity of a game winner; a progressive jackpot total; an explanation of game play in real time as the game is being played, in order to introduce bystanders to the game; a current tournament status involving the game machine; an animation of a game title or a game logo; machine states, such as machine offline, a bill jam, a coin jam, a door open, or an attendant-required state; an advertisement; statistics, such as past payouts at the game machine, a histogram of past payouts of the game machine, a summary of most recent payouts of the game machine, or odds of winning a payout at the game machine, etc.
  • A comprehensive description of an electronic table game system that uses images of virtual playing cards and other virtual game pieces across one or more player, dealer, and/or common displays is provided below. But first, further description of the exemplary candle display, highlighting further features, is given precedence and provided immediately below.
  • Exemplary Candle Display
  • FIGS. 75-79 show example implementations of the candle display 1400. In the illustrated implementation shown in FIGS. 75-76, the candle display 1400 includes a dual instance of a candle 1402, on either side of a single display screen 1404. Other configurations and combinations of the candle 1402 and the display screen 1404 are contemplated within the scope of the innovative candle display subject matter. The illustrated version of the candle display 1400 is an intelligent signage/candle visual device that combines the visual display panel 1404 with the candle 1402. The candle display 1400 provides intelligent game information visually, being in communication with an electronic gaming table 60 (or other gaming device). The candle display 1400 can provide improved game information and game state (typically software states/statuses) and/or the current machine state (typically hardware or hardware/software states/statuses) as compared with conventional candles or static displays. As introduced above, game information and statuses can include, but are not limited to, game titles, bet minimums and maximums, game rules, jackpot totals; advertisements, statistics, odds, blow-by-blow real-time explanation of game play for the sake of attracting bystanders, etc. Machine information and statuses can include, but are not limited to, machine offline states, bill jams, door open states, “attendant-required” conditions, etc. Custom graphics can also be displayed, including advertisements and promotions.
  • FIG. 77 shows another implementation of the candle display 1400, in which the candle 1402 is disposed horizontally across the top of the display screen 1404. FIG. 78 shows another implementation of the candle display 1400, in which the candle 1402 is disposed vertically on top of the display screen 1404. FIG. 79 shows another implementation of the candle display 1400, in which the candle 1402 is integrated with a pole member supporting the display screen 1404.
  • In some implementations, the candle 1402 and the display screen 1404 do not have to be physically united in the candle display 1400, but are instead communicatively coupled, for example, via the exemplary candle display controller 1406 to be described in greater detail below. The candle display controller 1406 enables participating candles 1402 and participating display screens 1404 to act in conjunction with each other, under harmonized control. For example, the candle display controller 1406 may instruct a candle 1402 to flash lights indicating a big jackpot winner, while instructing a display screen 1404 to flash graphics in syncopation with the flashing of the candle 1402. Simultaneously, the candle display controller 1406 may instruct the display screen 1404 to scroll festive text and graphics, for example, “You have just won a $10,000 jackpot!”
  • It should be noted that the exemplary candle display 1400 can serve two or more signaling purposes at once. For example, the candle component 1402 may signa
