  • the bonus prize that is awarded is determined by the game controller 101 according to a random selection process.
  • the random selection process may be weighted so that smaller value bonus prizes statistically occur more often than the higher value bonus prizes.
  • a base game which may for example be a spinning reel game is played (step 502 ).
  • a bonus feature occurs according to random criteria (determined in step 504 ).
  • the bonus feature may be the alignment of say, three symbols alongside each other on a payline of the gaming machine, or the occurrence anywhere on the screen of say, three special or wild symbols.
  • the bonus feature may be the alignment of say, three symbols alongside each other on a payline of the gaming machine, or the occurrence anywhere on the screen of say, three special or wild symbols.
  • An alternative arrangement is for the bonus feature to be triggered completely independently of the base game, for example based on turnover of the base game as described in Australian patent no. 754689, the contents of which are hereby incorporated by reference.
  • the prize pool that is played for may be selected randomly.
  • the gaming device 202 displays the feature game (step 506 ). This may be under the control of the same computational device 102 that controlled display of the base game.

This alternative embodiment may have particular application to a plurality of linked gaming machines.
  • a feature game will be played, as indicated at step 508 .
  • an outcome of the feature game will occur, as indicated at step 510 .
  • the outcome of the feature game will determine whether a bonus prize is awarded.
  • there are a plurality of different bonus prizes that can be won from the feature game the game controller determining which one, if any, of the bonus prizes is awarded according to random criteria, which may be weighted towards the lesser value bonus prizes.
  • one of the bonus prizes is always awarded from the feature game so that there are only winning outcomes of the feature game.
  • the game controller assesses whether the player is eligible for a special or random prize, as indicated at step 512 .
  • the system reverts to the base game, as indicated at steps 518 and 501 .
  • the game controller 101 determines that the player is eligible for a special prize then the value of that special prize will be determined, as indicated at step 514 , and the player will then be paid that special prize out of a progressive prize pool or other prize funds source. Thereafter the system will revert to base game play, as indicated by steps 518 and 501 .
  • control of the display 106 of the gaming device 202 was transferred to the jackpot server 207 , it is returned from the jackpot server 207 to the game controller 101 that controls play of the base game, as indicated in step 518 .
  • the bonus prize and the special prize are paid.
  • the gaming device 202 may display on the display a single combined prize representing the sum of the bonus prize and the special prize and displaying this as the result from the feature game.
  • the special prize when the special prize is to be awarded, it is awarded instead of the bonus prize.
  • all values of the special prize are preferably higher than the advertised bonus prize for the feature outcome.
  • the special prize need not be of the same type as the bonus prize, although it may be of the same type (e.g. both are prizes in credits).
  • the player may be presented with representations that indicate that the bonus prize at least sometimes, or perhaps often depending on the particular implementation, is higher than the advertised amount. With continued play, the player may notice that when the prize varies from the advertised, the extent to which it is higher than the advertised prize also varies.
  • the gaming machine may display a special sequence on a display 106 , play a sound and/or otherwise distinguish the prize from the normal bonus prize associated with the feature outcome. In one embodiment, whether or not a special sequence, sound or other distinguishing media is presented to the player when the special prize is awarded, no additional display of symbols representative of the random selection process in step 514 is made by the gaming device 202 .
  • the special prize may be displayed separately to the bonus prize. This creates a different impression to the player, who sees that they have won the advertised prize for the feature game outcome (or bonus feature in the embodiment where a feature game is omitted) and with continued play sees that a separate prize is awarded at random.
  • the player's eligibility for a special prize can be assessed on various bases. For example, each time a player is awarded a feature game the system may generate an additional special prize, of varying amounts, as randomly determined. Alternatively, only those players who win a particular bonus prize, for example the lowest available bonus prize in the embodiment where every play of the feature game results in a prize, may be eligible for the special prize, somewhat in the manner of a consolation for the player. A further alternative would be for the player to be awarded a special prize in conjunction with all feature outcomes, but the quantum of the special prize that can be awarded might vary between say a very low prize or prize range, and a quite significant prize or prize range. Eligibility may also be dependant on the player placing an additional bet during play of the game in which the bonus feature may occur.
  • An alternative embodiment to the process shown in FIG. 5 is for the player to be awarded a special prize where a bonus feature has occurred but where no feature game is played and consequently no feature game outcome is achieved.
  • the eligibility for the special prize may for example be dependent on which bonus feature has occurred. Eligibility for the special prize is therefore not tied to the provision of a feature game.
  • the player when the bonus feature occurs, the player may be directly awarded a bonus prize and is also eligible to be awarded the randomly awarded special prize.
  • a gaming machine may maintain a plurality of progressive prizes or a plurality of linked gaming machines may communicate with a progressive controller, which may be the jackpot controller 207 , to maintain a plurality of progressives, the game controller 101 selecting one of the bonus prizes at random according to a weighted selection process.
  • the selection process for the bonus prizes may be similar to the selection process described herein below for the special prize. However, those skilled in the relevant arts will appreciate that alternative processes exist and could be developed.
  • each progressive prize may be awarded as a bonus prize when a particular combination occurs during play of a game.
  • a single particular combination may be used as the bonus feature, following which the player could be awarded any one of the bonus prizes.
  • the gaming machine or linked gaming machines may offer a plurality of different fixed prizes on the occurrence of a bonus feature, there being a random selection of which fixed prize is won when the bonus feature occurs.
  • one of the progressive prizes may be awarded with three “J” symbols occur along a pay line of a spinning reel game.
  • This progressive prize may be constrained, either statistically and/or by fixed constraints to be within a certain range.
  • the gaming machine or the progressive controller if provided may cause the award of that progressive prize.
  • the special prize may be in the form of a payment by the gaming machine operator that is not incorporated into the return to player calculations.
  • the jackpot server 207 may incorporate a random number generator 113 which allocates special prizes to different players, depending on the random number selected once a player achieved a feature outcome.
  • the special prize awarding system could be revenue neutral, that is, over time, the system could be programmed to return to players all of the finds contributed by individual machines, but in different value amounts, in the manner described above. Thus, the volatility of the system would increase, yet the overall return to player percentage would remain consistent.
  • the random determination may instead be made by a random number generator 113 located in the housing of the gaming device 202 and may also be the same RNG 113 used for other aspects of game play.
  • the random number generator 113 might have say, 5000 available numbers for selection each time a player becomes eligible for a special prize. Numbers 1 to 1000 might be allocated as a zero prize, numbers 1001 to 2000 might be allocated as a first level of prize, numbers 2001 to 3000 might be allocated a second level of prize and so on. Of course, there are a wide variety of ways of randomly awarding amounts to players on the occurrence of a triggering event, and the above example is intended to be simply illustrative of how the invention might be put into effect. Step 512 of the process would then involve the random number generator 113 selecting a number between 1 and 5000 which would then determine whether a prize was to be awarded, and if so, the quantum of the prize.
  • the system will greatly increase a player's interest in the game because if, in normal play, after the bonus feature has been triggered, the feature game has been played resulting in the feature game outcome associated with the lowest bonus prize, once the feature game outcome is known, the player still has a second opportunity to win, thereby increasing the player's enjoyment and anticipation in the feature game and feature outcome.
  • the system can be implemented without changing the return to player percentage of a gaming machine, if it is implemented on a stand alone machine, or a gaming system, if implemented across a plurality of linked gaming machines controlled by a central jackpot controller within a jackpot pool.
