COMPLETE SPECIFICATION STANDARD PATENT Invention Title: Slot machine game Find the prize The following statement is a full description of this invention including the best method of performing it known to us:- Slot machine game Find the prize Introduction The present invention relates to gaming machines of the type generally referred to as slot machines, fruit machines or poker machines, and in particular the invention provides a new game played on such a machine.

Players who regularly play gaming machines quickly tire of particular games and therefore it is necessary for manufacturers of these machines to come up with innovative games or game features that add interest to the games provided on such machines in order to keep the players amused and therefore willing to continue playing the game.

Description of the Prior Art Gaming or poker machines have been well known in Australia, the state of Nevada, and many other jurisdictions for many years and have more recently gained considerable popularity throughout the world, with quite substantial amounts of money wagered on these machines. There is a growing tendency for State governments to legalise the use of gaming machines by licensing operators, with resulting revenue gains through licence fees and taxation of monies invested. The licensed operation of ooogaming machines is the subject of State legislation and regulation. This 20 regulation most always dictates a minimum percentage payout for a gaming machine. For example, a minimum of 85% of monies invested must be returned as winnings, and manufacturers of gaming machines therefore must design their machines around these regulatory controls.

With the growth that has occurred in the gaming machine market there o 25 is intense competition between manufacturers to supply the various existing and new venues. When selecting a supplier of gaming machines, the operator of a venue will often pay close attention to the popularity of various games with their patrons.

Therefore, gaming machine manufacturers are keen to devise games which are popular with players, as a mechanism for improving sales.

In particular, manufacturers regularly devise new games which have not previously been seen on slot machines in order to stimulate renewal of player interest.

Any discussion of documents, acts, materials, devices, articles or the like which has been included in the present specification is solely for the purpose of providing a context for the present invention. It is not to be taken as an admission that any or all of these matters form part of the prior art base or were common general knowledge in the field relevant to the present invention as it existed in Australia before the priority date of each claim of this application.

Throughout this specification the word "comprise", or variations such as "comprises" or "comprising", will be understood to imply the inclusion of a stated element, integer or step, or group of elements, integers or steps, but not the exclusion of any other element, integer or step, or group of elements, integers or steps.

Detailed Description of the Preferred Embodiments In the following detailed description, the methodology of the embodiments will be described and it is to be understood that it is within the capabilities of the non-inventive worker in the art to introduce the methodology on any standard microprocessor based gaming machine by means of appropriate programming.

Referring to Figure 1, the illustrated embodiment of the invention is housed in a conventional slot machine cabinet 10 including a prize display 12, a coin entry slot 13, a payout tray 14 and internally mounted game control processor circuits (refer to Figure 6).

Preferably, the game display means 11 comprises a video display screen 11 controlled to display a game image divided into a matrix of elements or player selectable zones. The video screen is preferably of the touch sensitive variety, having an array of touch sensitive areas located on its display surface with one such area associated with each matrix element 40-54 (refer to Figure The player may select one of the matrix elements (eg. 41) by touching the screen within the area of the respective element to be selected, thereby causing the image in the element to change to reveal whether or not a prize value is associated with that zone. Additional player controls may be implemented by displaying images 18, 19, 20, 21, 22, 23, *.*corresponding to controls on the screen such that when the control images are touched, the associated function is caused to be performed.

Referring to Figure 2, a screen layout is illustrated for a first 20 embodiment of the invention. In this embodiment, one such player control is .a gamble button 23, which when touched causes a game to be initiated.

Additionally, buttons 18, 19, 20, 21 and 22 enable bets of 1-5 credits to be placed on each game.

.First the player selects his bet which will be deducted from his available credit when the game is commenced (and will cause the prize to be multiplied by the number of bet units selected). In some embodiments bet selection may not be provided and all bets will be of one unit or, alternatively, the game would be played as a feature or bonus game where the player is provided the opportunity to improve the prize won in the preceding main game.

After the player has selected his bet using buttons 18-22, if applicable, he starts the game by pressing the start button 23, and may then immediately select an image element by touching the appropriate screen position (eg. 49).

In the event that the player does not select a zone within a predetermined time (eg 3 seconds) the game will commence revealing zones randomly until all zones with associated prize values have been revealed.

9 The game will reveal zones at a predetermined rate, of for example, one zone every 2 seconds. When each zone is selected, either by the player or the game, the selected zone will change state to indicate that it has been selected and remain in its new state until the end of the game. Also, if any selected zone has a prize associated with it, it will indicate the value of that prize. In the event that the game continues until there is only one unselected zone and the player still has not made a selection, the last zone will be automatically taken to the player selection; and by definition this zone must have a prize associated with it, otherwise the game would have already ended.

In the event that the zone selected by the player, or allocated to him has a prize associated with it, that prize (or its value) will be credited to the player.

Referring to Figure 3, the game of Figure 2 is shown, when the player has selected a zone prior to the game making any selections. In this case zone 49 was selected and has revealed the message "no prize". In some games, as the selection of zones by the slot machine progresses, the pattern of "prize" messages and "no prize" messages will provide clues to the player as to the location of other prizes, due to the expected layout of prizes.

Referring to Figures 4 and 5, while the player does not make a selection 20 the game selects zones periodically and, any associated prize indicia will be displayed (2 credits in the case of zone 54) to reveal a prize value. In the event that the player selects a zone associated with a prize, the prize is awarded to the player. The prize will be the value revealed (100 credits in .the case of zone 68) multiplied by the number of credits bet, if appropriate.

Game selections and player selections are preferably indicated differently, for example by changing to different colours.

Referring to Figure 6, a flow diagram is illustrated to show the logic of a control program which controls the operation of the game. From this diagram it will be noted that, after starting, the machine awaits selection of a bet by the player and the touching of the start button 23 to commence the game.

The control program then causes the display of an image comprising a matrix of image elements or zones and randomly associates prizes with a predetermined number of displayed indicia. The game image may be the same for each game or may be a variation on the same theme with different backgrounds and orientations of characters etc. The game then waits a predetermined period and if the player has not made a selection the game tests that the number of unselected zones is greater than one and the number of hidden prizes is greater than zero and, if so, the game selects another zone.

When the player makes a selection or if there is only one zone left unselected, the game checks to see if the player has won a prize and if so credits the player with the prize and the game ends. In the event that the player has not made a selection and there are no prizes remaining hidden the game also ends.

It will be appreciated that while the flow diagram of Figure 6 shows a linear program sequence the testing for player selection may be occurring continuously by way of a hardware interrupt subroutine triggered either by a timer or an input detection circuit, in which case the input testing step may occur at any point in the loop. This alternative arrangement is illustrated in the flow diagram of Figure 7.

The program to implement the sequence of Figures 6 or 7 runs on a 15 standard gaming machine control processor 31 as illustrated schematically in Figure 8. This processor forms part of a controller 30 which drives the *display screen 11 and receives touch input signals from touch sensors 32 as well as receiving coin input pulses from a coin chute mechanism 33 and driving a coin payout mechanism 34.

20 In a further embodiment of the invention, the game does not end when a player makes their selection. Instead, the player is given two (or possibly more) selections and can potentially win more than one prize. In one embodiment, the player may make 2 selections before the game ends with the game ending when the player makes his second selection, or when the number of remaining selections available to the player is equal to the number of elements remaining available to be selected. However, games could be configured to allow the player larger numbers of selections than one or two.

While the above description envisages the system revealing matrix elements one at a time until the player makes a selection, it is also possible to provide a feature where either the player or the machine may reveal matrix elements a number at a time. For example, a player may 'win' eligibility to a higher level of the game in which he may select multiple elements simultaneously. This could be done by the player touching a primary element and one or more adjacent elements to the primary element being selected as well. The adjacent elements would be in a predefined relationship with the primary element, for example the element to the immediate right of the primary could be associated with the primary element if the player was awarded a level where 2 symbols are revealed at a time, and the elements to the immediate right and left if the player was awarded a level where 3 symbols are revealed at a time, etc.

The game may also include playing levels where the machine selects multiple elements thereby encouraging the player to play faster.

Referring to figure 9, a game screen is illustrated for a game that may be played on a gaming machine according to the present invention.

This screen shows a plurality of matrix elements 40-75, with which a variety of prize values (including no prize or zero values) are associated.

When a game commences, these prize values would be hidden and perhaps a graphic design of some kind displayed over the top. The graphic design may have no bearing on the location of any of the prize values, or could provide clues to the location of some or all of the prize values as in the case of the 15 Figure 10 example of an image of a football field with players engaged in a football game.

*In the example of Figure 10, the concentration of football players around element 61 might give a clue to the location of the 'wild' indicia located there for example by suggesting that the unillustrated ball of the 20 football game would be located there.

In this game, a prize could be paid for the first element with an associated prize value selected by the player as previously described.

*".Alternatively, the game could require the player to select two matching elements with each having the same prize value, or a wild symbol and one element with a prize value. The elements selected if non-winning (ie, nonmatching) can either be re-hidden by re-displaying the overlying graphic or could remain revealed, in which case prize values revealed will be no longer available for matching with newly selected elements. The gaming machine can progressively reveal elements as well, either one at a time, or in groups of two or more, thereby removing those elements from the set from which the player may select.

The game can either end when the player selects a matching pair or, when there are no more pairs to select. Alternatively, the game may continue after the player makes a first match, such that he has an opportunity of winning more than one prize per game.

If the elements are re-hidden after each non-winning player selection, the game may terminate when all of the elements have been revealed either by the player or the machine.

The game of the present invention may also be played as a tournament against other players. In this case referring to Figure 11, the gaming machines 100a-100g in an installation will be connected to a controller 101 and in the illustrated embodiment this is done via bank controllers 103. The controllers 101 may be connected to an operator terminal 104 or other system components such as accounting systems and other jackpot controllers. Each set of machines (eg, 100a-100b) connected to a bank controller 13 may also be connected to a central display 106 associated with that bank for displaying information relating to that bank of machines or information relating to the gaming machine installation in general. When a tournament game is played the game, or the results, or the progress of the game may be displayed on the respective bank display 106.

Tournaments may be played on just one bank, a plurality of banks or 0 the whole gaming machine installation, however it is preferable if the number of machines in the tournament is less than or equal to the number of player S* selectable elements in the game.

S: 20 When a tournament commences all of the machines participating will display a common game which may also be displayed on the bank display.

The tournament controller 101 will send signals to the participating machines 100 and bank displays 106 when a tournament is about to commence indicating that they should display the tournament game screen (eg, the screen of Figure 101) at the end of the next game cycle. When all of the machines report that they have displayed the tournament screen, the controller will wait briefly to give the player on the last machine to report in, time to realise that a tournament is about to commence and then a signal will be issued to commence the tournament. The participating machines, when they receive this signal, will indicate to their respective players to commence playing and the players should then commence selecting elements. Elements selected by each player will be revealed to all other players in the tournament and progress will also be displayed on the bank display. In the preferred embodiment each player gets only one selection and the tournament will run until one player wins a prize.

13 The object of the tournament feature is for each eligible player to play directly against each other player in the tournament. Hence, when the tournament is triggered during play of the base slot game, the same feature game will be displayed on every participating machine. When one player selects a location, then that same location will be marked off on every participating machine's screen. This adds to the suspense of the feature since the players can watch the elements being progressively revealed. For each element that is revealed and does not uncover the bonus prize they will have a greater chance of selecting the bonus themselves (since the number of elements to choose from has been reduced). However, the longer they wait the more they increase the chance of someone else selecting the bonus prize first. If a bonus does not get revealed during a tournament it will be carried over to be included in the next tournament.

There are several different ways that the tournament may operate.

15 For example: Multiple prizes may be arranged among the elements where at least one is **0 *a bonus prize such as a progressive jackpot. Some elements may contain no prize, or each element may have at least a consolation prize. Each participant will get exactly one selection, and will be given the prize (if S: 20 applicable) that relates to the element that they select.

There may be just one bonus (eg. progressive jackpot) prize. Each player will be allowed a maximum of one selection, but the feature will be over :.00 as soon as the bonus has been revealed. Hence, participants who have not: .made a selection at the time that the bonus is revealed will forfeit their 0 0 chance to make a selection.

As for previous embodiments, but in addition, the controller may randomly reveal elements in addition to the elements selected by the various players.

For embodiments where there may be more participants than elements to choose from, or where the controller may reveal elements, player selections may operate on a "first-in-first-served" basis. Hence, if players aren't quick enough they will miss out on the opportunity to make a selection.

As for previous embodiments, but where the players may be allowed to make more than one selection (eg. exactly 2 selections, or a number of selections that is weighted by the size of the bet on the game being played 0 o when the tournament was triggered). The additional selections may have to be made in order (ie a player cannot make a second choice until everyone has made a first choice), or alternatively, the selections might be made whenever the player chooses.

As well as, (or instead of) the prizes being revealed on each participant's screen as other participants make selections, the number of the gaming machine applicable to each selection may be revealed on the participants' screens for each element.

In another embodiment a similar tournament feature game is provided on a multi-station terminal. In this case the feature game will operate in a similar manner to the tournament described above, except that there will be one central screen around which the players are located and from which they all choose their zone selections. Preferably it will be a large touchscreen in the centre of a ring of players such that the players can all touch any point on the screen as necessary. All players will select a zone on the screen from the same screen. Preferably this is implemented such that the players each choose in order (eg. clockwise from the first player position or terminal) so that the machine can recognise which player chose which location.

When a player wins the tournament, the location of the winning machine, the prize and other celebratory images will be displayed on the participating bank controllers 106 and the winning machine 100 will play by a win tune.

It will be appreciated by persons skilled in the art that numerous variations and/or modifications may be made to the invention as shown in the specific embodiments without departing from the spirit or scope of the invention as broadly described. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive.
