Abstract:
A method for playing a poker game along with an auxiliary game, which depends on the poker game outcomes, is provided. The outcomes of the poker game are divided in three categories: credit events, no-credit events and non-event holds. Depending on their categories, outcomes influence the auxiliary game in different ways. The preferred way the auxiliary game works is by monitoring credit and no-credit events with a time window having neither a beginning nor an end; the amount of information monitored being constant. When a predetermined number of credits is accumulated within the monitoring window, an auxiliary prize is awarded. The invention also provides ways to display the information monitored by the auxiliary game so that this information is easy for players to understand and to follow. Accordingly, the invention provides an enhanced play experience that maintains excitement.

Description:
RELATED APPLICATION 
     The present patent application is a continuation-in-part of Ser. No. 09/496,280 entitled “METHOD FOR PLAYING AN AUXILIARY GAME WITH PRIZE REWARDING SYSTEM”, filed Feb. 1, 2000 now U.S. Pat. No. 6,416,406. 
    
    
     FIELD OF THE INVENTION 
     The present invention relates to an apparatus and a method for playing a poker game along with an auxiliary game. More particularly, the invention describes a method including steps of evaluating the outcomes of a poker game and using them as incoming information of an auxiliary game. 
     BACKGROUND OF THE INVENTION 
     In recent years, on numerous electronic gaming apparatus, various features such as bonus and auxiliary games have been developed. The goals of these features are: 1) to maintain players&#39; interest and 2) to urge players to play for longer periods, therefore affecting the apparatus level of use and generating more revenues for its operators. 
     To achieve that goal, one known strategy consists in a progressive jackpot bearing a potential prize of much more impressive value than the others available prizes. Therefore, while playing, an increased of players&#39; interest is caused by the possibility of winning this attractive jackpot. However, players have no urge to keep playing on the same apparatus. They can win the jackpot on any apparatus bearing this progressive jackpot, sometimes in more than one gaming facility. 
     Another strategy consists in the addition of a secondary game accessed via the occurrence of particular events during the playing of the primary game. These secondary games provide players with chances to increase their wins or to win special prizes, said special prizes being awarded only via the secondary game. 
     However, the excitement created via the secondary game does not last long. Furthermore, the excitement generated by the secondary game is not effective during the primary game play; players have no way to predict when a secondary game trigger is about to occur. 
     Jackpots and secondary game triggers are usually awarded according to single primary game outcomes. While playing the game, the player gets no hint that one jackpot or secondary game trigger is about to be yielded. Therefore, these games do not succeed to create prolonged periods of excitement. 
     A third strategy is the one described by Marnell in his U.S. Pat. No. 5,393,057. In the example, a bingo matrix display (the secondary game) is coupled to a poker game (the primary game). The occurrence of different outcomes in the poker game can yield modifications in the bingo matrix display. According to the standard rules of bingo, players win prizes in the auxiliary game when a predetermined pattern is present in the bingo display. An auxiliary game win requires winning while playing the poker game. Furthermore, it requires yielding predetermined poker hands to modify the bingo matrix accordingly. The downside of this method is that players do not feel the importance or the effect of each single play of the primary game on the auxiliary prize. However, they do feel the necessity to keep playing the game to avoid skipping over the outcome allowing them to win the auxiliary prize. 
     Another strategy available consists in progressive jackpots applied to live casino games played at tables. This solution has the same disadvantages as the above-mentioned strategies. 
     Yet another strategy is to monitor a number of predetermined outcomes in the primary game and to allow the player to access an auxiliary game when a predetermined number of these outcomes have occurred. Usually, this auxiliary game is a prize multiplier. Most of the time, the monitoring of these outcomes is neither available nor displayed to players; consequently players cannot foresee when they will access the auxiliary game. Often, they are not even aware of which outcomes are used to control access to the auxiliary game. However, even when the outcomes are known, players have no time limit to accumulate them, therefore no urge to play. 
     Another strategy is to give access to an auxiliary game wherein players gather points or the like, and are rewarded according to the number of points gathered. These points are both attributed and accumulated in the auxiliary game and are not a function of the primary game plays at all. The only link between the auxiliary game and the primary game consists in the trigger events of the primary game that control the access to the auxiliary game. 
     As a result, there have been no successful strategies developed to maintain players&#39; interest throughout their participation in a game; none transmits to the players the conviction that each single play has its importance, without exception. 
     SUMMARY OF THE INVENTION 
     Accordingly, it is an object of the present invention to provide a method of playing an auxiliary game that maintains the interest of players over numerous plays of a poker game. Furthermore, it intends to increase the pleasure generated by the playing of the poker game. Another object of the invention is to provide a game wherein each playing of the primary game has its own importance. Another object is to provide an auxiliary game and a method of playing said auxiliary game creating an incentive for players to keep using the same gaming apparatus, therefore to play the same auxiliary game with the same game history. This in turn increases the profits generated by the apparatus. 
     It is also an object of the present invention to provide a method to allow the awarding of a progressive payoff, said progressive payoff having the effect of creating and maintaining additional interest. Another object is to display the information regarding the playing of the auxiliary game during the plays of the primary game to sustain players&#39; excitement. A further object consists in concurrently monitoring multiple auxiliary game prizes, therefore allowing players to sustain suspense over the possibilities of winning multiple auxiliary game prizes at once. A further object of the invention consists in maintaining players&#39; excitement by allowing them to gather whatever requirements to win prizes in the auxiliary game in a number of plays greater than the number of plays monitored by the auxiliary game. Players&#39; chances of winning an auxiliary game prize are therefore increased. 
     According to the above objects, a method of playing an auxiliary game awarding prizes played along with a poker game is provided. The method comprises the following steps: 1) establishing a first class of poker outcomes and associating it with a first auxiliary income category labeled “credit events”, 2) establishing a second class of outcomes and associating it with “no-credit events”, 3) establishing a third class of outcomes and associating it with an auxiliary income category being “non-event holds”, 4) monitoring credits over a predetermined number of said events, and 5) awarding a prize when a number of credits corresponding to a predetermined criteria is present in the auxiliary game. The above-mentioned method gives the players the advantage of avoiding no-credits with a series of non-event holds and credit events, as a result of prolonging suspense and increasing the players&#39; chances of winning an auxiliary game prize. 
     Furthermore, the auxiliary game monitors auxiliary incomes over a predetermined number of credits. However, when the maximum number of credits available to be monitored is reached, the auxiliary monitoring system is not emptied; it always keeps track of the latest auxiliary incomes up to a maximum volume of information. Consequently, it creates a monitoring window “in time” following the poker plays. As a result, each auxiliary income affects more than one auxiliary game prize evaluation. Each single auxiliary income can have a determinant influence on multiple potential prizes within the auxiliary game regardless of the moment of the auxiliary income entry. 
     A preferred embodiment of this invention comprises an electronic gaming apparatus in which a poker game is linked to an auxiliary game monitoring system operating according to the method described above. The information monitored by the auxiliary game is displayed in the upper section of the electronic display. Below are the cards allowing the playing of the poker game. This information is easy to read and easily understood by any players, novices as well as experts. In this embodiment, an outcome evaluated as higher than two pairs is a credit event, a loss is a no-credit event, and a poker outcome evaluated as a pair or two pairs, whether or not it has a poker play value, is a non-event hold in the auxiliary game. A monitoring matrix keeps track of credits and no-credits on the screen. At least one progressive prize associated with the matrix display is available according to credit-based criteria. To play the auxiliary game, players must place a flat additional bet (a.k.a. side bet), said flat additional bet being the same from play to play and independent of the poker game bet. 
     Another embodiment is provided in which the auxiliary game is played in association with a poker game wherein no outcomes are evaluated as non-event holds. Therefore, all poker outcomes generate an input in the auxiliary game. Consequently, the evaluation of an auxiliary prize cannot be done over more poker outcomes than the auxiliary input monitored. Furthermore, a mystery auxiliary prize is awarded to players who succeed in yielding an auxiliary game matrix bearing information that corresponds to mystery criteria. 
     A third embodiment of the invention consists in an auxiliary game following the same rules of evaluation of poker plays as the above described first embodiment. However, the monitoring of events by the auxiliary game monitoring system and the criteria used to determine credits, no-credits and holds are different. The auxiliary game monitoring system keeps track of the credit events provided by the poker game until a no-credit event occurs. This no-credit event has the effect of clearing away every current credit. However, non-event holds have no effect on the monitoring matrix. Consequently, the number of plays required to win a prize depends on the number of non-event holds occurring.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     FIG. 1 presents an electronic gaming apparatus  101  for the playing of an electronic game such as a poker game along with an auxiliary game. The electronic gaming apparatus  101  comprises controls  106  for the playing of the poker game, money input/output system  107  embodied differently according to whether or not the apparatus allows cashless transactions, and an electronic display  105 . The electronic gaming apparatus  101  can comprise more devices in accordance with the requirements of the facility wherein the apparatus is installed. However, the systems  105 ,  106  and  107  are the essential ones required for the playing of a poker game in accordance with the present invention. 
     FIG. 2 shows the typical play screen of an electronic gaming apparatus  101  comprising a poker game along with an auxiliary game. The lower section  102  of the screen shows cards  103  used to yield poker hands and poker related information  104 , while the upper section  110  presents the monitoring matrix  111  and auxiliary game related information  112   a  and  112   b.    
     First Embodiment 
     A closer look at the auxiliary game section of the play screen  105 , FIG. 2, reveals the monitoring matrix  111  composed of numerous horizontal rows  113   a-e  and numerous vertical columns  114   a-l , the whole composing a matrix of cells  115 . Each matrix cell  115  is used to keep track of incoming information, said information is used afterwards to evaluate whether an auxiliary prize has to be awarded. Each column  114  bears the information corresponding to one poker play. Each row  113  has its own criteria  112   a  regarding the awarding of an auxiliary prize and its own auxiliary prize value  112   b . As the poker game progresses, the poker outcomes  103  are evaluated and processed as incoming auxiliary game information, which is entered in the monitoring matrix  111 . When new information enters the monitoring matrix  111 , the current information is scrolled one column to the right and the far right column  114   l  information is discarded to make room for new information on the left. This way, the amount of information monitored by the monitoring matrix  111  is constant at every play. 
     The information monitored falls into two categories: credits and no-credits. However, the poker outcomes  103  are evaluated to generate three (3) categories: credit events, no-credit events and non-event holds. Credit events occurring in the poker game have positive effects on the auxiliary game. No-credit events occurring have negative effects. However, non-event holds have no effect on the auxiliary game. Therefore, yielding a non-event hold during one poker play does not influence the auxiliary game; it is just as if no poker play has been played from the auxiliary game perspective. 
     The credits are displayed as asterisks  116  in the monitoring matrix  111  while no-credits are displayed as empty cells  117 . In connection with the playing of the poker game, credits  116  are entered in each cell of the first column  114   a . When a no-credit event occurs in the poker game, all of the credits present in the monitoring matrix  111  scroll one column to the right while the far left column  114   a  stays empty. After each entry of information in the monitoring matrix  111 , an evaluation is made in regard to auxiliary prizes available to be awarded. When one auxiliary prize is awarded, the credits participating in that prize are replaced by no-credits. This way, only the information regarding credits that can participate in awarding an auxiliary prize is present in the monitoring matrix  111 . 
     The method and first embodiment of the present invention will be more readily understood by reference to the following example. However, this example is presented to illustrate the embodiment rather than to limit the scope of the invention. 
     EXAMPLE 
     Please note that the sequence of outcomes of the following example is presented for explicative purpose only. The example information is chosen regardless of the probability of occurrence of each of the poker outcomes, only to clearly illustrate each step of the method. As a result, the method will be more easily reproduced. 
     First of all, the auxiliary game of this embodiment consists in a side bet type of game. In other words, to participate in the auxiliary game, players must place an additional bet. This bet is used to provide money to award the auxiliary prize, while said prize is determined according to the side bet regardless of the bet placed on the poker game. Furthermore, the side bet always has the same value regardless of the bet value of the poker game. Moreover, the side bet is constant through all plays of the poker game. Players have only two side bet options: whether or not to place one. According to the side bet being placed, the poker outcome is evaluated at the end of the play and new information is entered in the monitoring matrix. If there is no side bet, the poker outcome is not evaluated in regard to the category it would have been and used as. However, even with a side bet, if the poker outcome is a non-event hold, no new information takes part in the auxiliary game. Consequently, obtaining non-event holds allows players to increase the number of plays in which a particular credit can be effective in the auxiliary game. 
     To start a play session, the player first inserts coins, a smart card or whatever monetary value used in the gaming facility. From then on, these coins constitute the player account from which is decreased each bet placed on the poker game and the auxiliary game. Each time a bet is placed, the player account is withdrawn from the same value. Each time the player wins, the prize value is added to the account. When the player ends it play session, he cashes out the entire account, which increases the smart card value or is delivered through a coin drop for example. 
     As an example, the monitoring matrix of FIG. 7 is displayed at it appears when the player comes to at the electronic gaming apparatus. The player inserts enough money in the apparatus for his whole play session. He can place a bet of one (1) to ten (10) coins on the poker game and a fixed side bet of one (1) coin. Regardless of the bet placed on each play, when there is at least a one-coin bet on the poker game, the player can start his play by pressing the PLAY button. Afterwards, five (5) cards are drawn from a virtual card deck and displayed on the screen. The player chooses which cards to hold; new ones drawn from the card deck replace the others. Once completed, the poker hand constitutes the final outcome of the poker play, which is evaluated. The player is awarded a poker prize according to the evaluation, the poker game prize distribution schedule, and the bet. 
     If the player has placed a side bet, the poker hand is also evaluated to determine its category. If the poker outcome is a credit or a no-credit event, the monitoring matrix is updated. However, if the poker outcome is a non-event hold, the monitoring matrix stays the same. 
     FIG. 3 presents the prize distribution schedule of the poker game while FIG. 4 presents the category evaluation criteria. Even if both are evaluation according to standard poker categories, the used criteria are not the same. Furthermore, the evaluation to determine whether a poker outcome has a positive effect on the auxiliary game is totally independent from the value of the poker outcome in the poker game. A “low pair” has no value in the poker game (FIG.  3 ); however it generates no negative effect on the auxiliary game (non-event hold, FIG.  4 ). The same way, poker hands evaluated as “high pair” and “two pairs” hands have a positive value that allows a poker prize to be awarded. Nevertheless, poker hands evaluated as “three of a kind” or higher are required to obtain a true positive effect on the auxiliary game. 
     The auxiliary prizes available are independent from row to row in the monitoring matrix. Each time a new entry is included in the matrix, each row is evaluated according to the current number of credits in the row cells versus the criteria for awarding an auxiliary prize for that row. Therefore, players can win multiple auxiliary prizes with the addition of new credits in the matrix. FIG. 5 lists the different requirements regarding numbers of credits for the different rows. Furthermore, FIG. 5 lists the auxiliary prize values. It is interesting to note that the highest one is a progressive prize. As a result, each time a side bet is placed, a predetermined percentage of the side bet increases the value of this progressive prize. According to the operator preference and the apparatus configuration, the progressive prize can be independent on each apparatus or shared by a bank of linked apparatus. With a shared progressive prize, the prize increases faster but is also won faster because of the increased number of apparatus having chances to win it at each play. 
     Once the poker game distribution schedule, the auxiliary game category evaluation schedule and the auxiliary prize distribution schedule are determined, the example can really begin with a series of poker outcomes. The player places bets (poker and auxiliary game bets) at the start of each play. As stated above, the apparatus bears an auxiliary game history (monitoring matrix information) as illustrated in the FIG.  7 . As the play session progresses, the information born by the monitoring matrix is modified. 
     FIG. 6 lists the series of poker outcomes and the corresponding auxiliary game entries used in the example. Furthermore, FIG. 6 lists the auxiliary prizes awarded as the poker game is played(shown as numbers of times the side bet value). In the example, the series of poker outcomes are evaluated while annexed figures state the information currently contained in the monitoring matrix. 
     When the play session begins, FIG. 7, no auxiliary prize is ready to be awarded. Consequently, each row  113  of the monitoring matrix  111  bears a number of credits lower than its criteria. Per example, the top row  113   e  bears four (4) asterisks  120   a-d  while the criteria associated with this row is to bear six (6) asterisks. Consequently, only two (2) new asterisks are required. However, upon entering new credits in the monitoring matrix, the player sees the credits scrolling to the right and disappearing. 
     The first poker play yields a “three ok a kind” category of outcome. As a result, the player is awarded three (3) times his poker bet. Because he also placed a side bet, the player is awarded credits. These credits are entered on the far left of the monitoring matrix by scrolling while the current information scrolls to the right. Entering the player new credits creates a new matrix as illustrated in FIG.  8 . Since no auxiliary game criteria are met, no auxiliary prizes are awarded. 
     The second poker outcome is “two pairs”. It allows the player to be awarded a poker game prize. However, since this outcome is evaluated as a non-event hold, it does not affect the information in the monitoring matrix. After the second poker outcome, the monitoring matrix bears the same credits as illustrated in FIG.  8 . Obtaining an outcome that does not affect the matrix information has a positive effect on the auxiliary game; it allows yielding the required number of credits with a greater number of poker outcomes. The third poker outcome is also evaluated as a non-event hold. Regardless of the fact that this poker outcome amounts to a loss in the poker game, obtaining this kind of outcome has a positive effect on the auxiliary game. Consequently, the auxiliary game depends on the poker game for its play but is independent of the poker outcome value. 
     The fourth outcome is a “straight flush”, therefore entering credits in the monitoring matrix. A new monitoring matrix is yielded, see FIG.  9 . According to criteria listed in FIG. 5, auxiliary prize are to be awarded. The rows  113   a - 113   b  and  113   d  bear numbers of credits matching their criteria. The asterisks surrounded by hatched lines  121  illustrate credits participating in the awarding of an auxiliary prize, as illustrated in FIG.  9 . Since three (3) criteria are met, an auxiliary prize having a value of fifty-seven (57) times the side bet is awarded. This number sums up the three (3) prizes awarded. Once awarded, the participating credits  121  are removed from the matrix. The new matrix is illustrated in FIG.  10 . It is now easily understandable why, even with credits entered in every cell of a column  114 , credits are sometimes displayed alone or as small numbers in some columns  114 ; the empty cells  117  are credits that already participated in awarding a prize. 
     The following outcomes (the fifth, sixth and seventh) do not influence the matrix. The eight forces the entry of credits in the matrix. It yields the matrix illustrated in FIG. 11 once the intermediary display stating which credits participate in the next prize has ended. The new prize awarded is not two hundred and fifty (250) times the side bet. It is a progressive prize. With each side bet placed, the progressive prize grew from a seed value to its current value. The prize awarded is determined when the matrix bears the required number of credits on the top prize row  113   a . Once awarded, the prize goes back to its seed value. Afterwards, it grows back as side bets are placed. 
     The last two (2) outcomes yield a monitoring matrix bearing new information. FIG. 12 illustrates the awarding of auxiliary prizes. Once again, more than one (1) criteria is met with one (1) entry of credits in the matrix. 
     It is interesting to note that, independently from the number of poker outcomes yielded, the original information born by the matrix scrolled six (6) columns to the right. However, the number of side bet placed is ten (10). This is advantageous for both players and operators. Operators see more money participating in the side bet (ten (10) coins) and less possibility of winning a side bet prize (six (6) entries in the matrix). Players have more poker plays to yield the required number of credits without seeing useful credits being dropped out the matrix. 
     FIG.  13  and FIG. 14 illustrate other ways to state the credits monitored by the auxiliary game. FIG. 13 illustrates a single row  130  bearing credits  116 . Associated with some of these credits  116   a - 116   b  is the last time they participated in a prize awarding and the criteria. It allows a more compact display of the auxiliary game. Furthermore, calculating the number of credits required remaining to be awarded an auxiliary prize is easy. When credits participate in awarding a prize, the credit being the last entered  116   a - 116   b  become associated with an informative tag  131   a-b . This tag  131   a-b  bears the criteria  132  met. Therefore, players know their needs regarding an accumulation of credits within the cells  133  on the left of the tag  131   a  as example; cells on the right of it  134  are not effective for any new awarding according to this criteria  132   a . FIG. 14 illustrates a more visual way to inform payers. Players have a predetermined number  140  of credits and no-credits to place on a platform scale  141 . However, the number of outcomes needed to complete it is undetermined. For each poker outcome, the outcome is evaluated and a weight is placed on a platform  142   a-b  according to the outcome evaluation. If the outcome is a non-event hold, no new weights are placed. When all weights are on the platforms  142 , the player is awarded according to the scale reading  143 . As a result, the last option offers a known beginning to the auxiliary game accumulation of credits. However, the end is unknown; it depends on the number of non-event holds. 
     Second Embodiment 
     This embodiment consists in the use of only two (2) categories of outcomes: credits and no-credits events. With this embodiment, the same kind of monitoring matrix  111  can bear credits as the play progresses. Three (3) major differences exist between this embodiment and the first. 1) For the auxiliary game, Poker outcomes are evaluated independently from their poker value. 2) There is no need of side bet; the auxiliary prizes available are determined in regard to the level of play of the poker game. 3) The auxiliary game bears a mystery prize. 
     As stated above, the poker outcomes are evaluated according to only two (2) categories; the non-event hold category does not exist. When a final outcome yielded contains a particular card or a particular number of cards from a predetermined set, it corresponds to an entry of credits in the matrix. However, when this criteria is not met, no-credits are entered in the matrix. An example of a criteria is to obtain a final hand bearing at least an ace. Like stated above, it is totally independent from the poker evaluation. Moreover, the embodiment can change the player strategy according to the credits born by the matrix and the initial poker hand. As a result, it creates a new challenge for players, a new dynamic of play. 
     Only one bet is required for this embodiment. According to the bet placed, the range of the auxiliary prizes available varies from none to all according to the bet value. As an example, if the player bets two (2) coins, only the high row  113   e  prize is available. If the bet is four (4) coins, the top three (3) row  113   c-e  prizes are available. And it gradually changes along with the bet level, with a maximum bet offering all of the auxiliary prizes. This way, the total payout of the game increases along with the bet level. Furthermore, the contribution to the payout of an auxiliary prize decreases as the bet increases. The top row  113   e  auxiliary prize contributes to half with a bet of four (4) coins than what it contributes with a two (2)-coin bet. For the same prize awarded, there is two (2) times the amount incoming when playing at four (4) than two (2) coins. Consequently, it is possible to create an interesting gradation of the payout versus the bet with this method. To avoid players increasing their bets only at favorable times according to matrix information, entries are operated only on rows bearing available prizes. As a result, credits are only entered on the top row  113   e  when players bet two (2) coins; the other cells of the same column  114   a  stay empty. 
     When playing at maximum bet, the player who yields a matrix bearing a predetermined shape is awarded a mystery prize. FIG. 15 illustrates this principle. In that example, cells bearing a dot  150  are the ones requiring credits. Cells bearing an X  151  require the absence of credits. Cells without any particular signs  152  are not evaluated. To be awarded the mystery prize, a player must place a maximum bet and have a matrix bearing the same pattern regardless of the non-evaluated cells  152 . FIG. 16 illustrates a matrix matching this criteria. With the mystery prize, players can win an auxiliary prize with a last entry of no-credits  155 . The matrix of FIG. 16 illustrates a situation when a player succeeded to match the above criteria with a last entry of no-credits. If the last entry were an entry of credits, the pattern would not have been matched. 
     Third Embodiment 
     The third embodiment used the same poker outcome categories as the first embodiment. The monitoring means consists in a stair-like matrix wherein for each row a maximum number of credits is possible to accumulate. Once the maximum number of credits is accumulated on a row, the prize associated to that row is awarded. The credits of that row are cleared away. According to the number of credits required, the prizes differ from on row to another. The row requiring the maximum number of credits is associated to the highest prize. To accumulate credits, a credit outcome must be yielded. Non-event holds do not influence the matrix information, while a no-credit event clears away the whole information born by the matrix. 
     FIG. 17 presents the monitoring matrix as used with this embodiment. At the beginning of the play session, the monitoring matrix is empty. To show an example of how this embodiment is played, the use of the series of poker outcomes of FIG. 6 is required. After the first outcome, a credit is added to the monitoring matrix. It yields a new matrix illustrated in FIG.  18 . The second outcome does not change the monitoring matrix since it is a non-event hold. The third outcome is a no-credit event; it clears away the credits accumulated in the matrix yielding the one illustrated in FIG.  17 . The fourth to the eighth outcomes yield back the matrix of FIG.  18 . In the case of the next outcome being a credit event, it yields a new monitoring matrix bearing credits as illustrated in FIG.  19 . As a result of no no-credit event being monitored since the last credit event, two credits are accumulated on each row. The lowest row of the matrix is composed of only two cells. Consequently, the prize corresponding to that row is awarded and the credits of that row are cleared away. However, since the maximum number of credits is not reached on the other rows, these credits are still present. A new credit can be monitored to pay a new prize if no no-credit event occurs before. 
     FIG. 20 states the standard steps for playing of a poker game along with an auxiliary game on an electronic gaming apparatus. The steps are described for the first embodiment. Even if the steps are not exactly the same for the other embodiments, the general steps are the same for all embodiments of the present invention. 
     First, the gaming apparatus receives money values  160  from the player, said money values are further used for betting. Bets are placed  161  according to player selections. When the bets are placed, the player actuates a control to start the play  162 . Five cards are drawn  163  from a card deck and displayed on the screen. At this time, the player can select  164  which card to hold and which card to discard. Once the selection is completed, the player actuates the play control again to continue the play. Cards are drawn  165  and displayed to replace the discarded cards. Afterwards, the gaming apparatus evaluates the poker outcome  166  to determine if the player is awarded a prize. According to the result of the evaluation  167 , a prize is either awarded  168  or not. 
     Once the poker play is completed, the gaming apparatus verifies the presence of an auxiliary bet  169 . In case no auxiliary bet is placed, it stops there. If a bet has been placed, an evaluation of the poker outcome  170  is operated according to the auxiliary game evaluation criteria. If it is a non-event hold, nothing happens. If it is a no-credit event, the monitoring matrix is updated  171  by a modification of the credit positions. If the outcome is a credit event, the current credits in the monitoring matrix are moved one space to the right to free space for new credits  172 . Afterwards, the matrix is evaluated  173  to determine if it bears the number of credits required on one row to award a prize. Accordingly, auxiliary prizes are awarded  174 . When all these steps are done, a new play may begin. 
     FIG. 21 is a block diagram of the components participating in poker plays and the auxiliary game. When starting the game, the bet controller  181  receives a bet selection from the player. According to the account controller  180 , the bet value is limited to a different value. As the bets being placed, the account controller  180  modifies the account value. Afterwards, the play can begin. The poker controller  182  signals to the display  187  the card to show, to hold, and to discard. When the poker play is complete, a signal corresponding to the poker outcome is sent to the poker payoff controller  183  and the class evaluation controller  184 . The poker payoff controller  183  evaluates the outcome and signals to the account controller  180  the amount awarded according to information coming from the bet controller  181 . At the same time, the display  187  receives information regarding the win value to display on the screen. Concurrently, the category evaluation controller  184  determines the category of the poker outcome according to the bet controller  181  signaling whether or not an auxiliary bet is placed. The category evaluated determines whether or not the auxiliary game controller  185  updates the monitoring matrix and the displayed matrix. As with the poker outcome, the auxiliary game payoff controller  186  evaluates if an auxiliary prize has to be awarded. It signals the auxiliary prize to both display  187  and account controller  180  to update information.
