DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIGS. 2 and 3, the preferred embodiment of a gaming apparatus 2 according to the present invention is shown to comprise a user input unit 21, a display unit 23, a game processor 22 coupled to the user input unit 21 and the display unit 23, and a proprietary computer program product 20 that configures the gaming apparatus 2 for playing a progressive game.
The user input unit 21 includes a BET key 24, a CHANGE key 25, a CONFIRM key 26 and a PAYOUT key 27.
The game processor 22 is the core of the gaming apparatus 2. In this embodiment, the game processor 22 is disposed on a game motherboard (circuit board). The computer program product 20 includes a computer readable storage medium (i.e., a memory unit) that is also disposed on the game motherboard and that comprises program codes for configuring the gaming apparatus for playing the progressive game. When the gaming apparatus 2 is powered on, the game processor 22 executes the program codes for performing the following steps of the computer-implemented method for playing the progressive game according to this invention:
Step a): Playing a main game
In this embodiment, the main game of the progressive game is a bingo game. Referring to step 41 in FIG. 4 and to FIG. 5, the game processor 22 enables the display unit 23 to generate a graphical user interface 200. The graphical user interface 200 includes a virtual bingo card 28 and a door frame 40. The virtual bingo card 28 includes a numerical bingo pattern in the form of a 5×5 numerical matrix, each element of which is randomly selected by the gaming apparatus. The door frame 40 includes left and right jambs 401, 402 and a strip décor 403 interconnecting top ends of the jambs 401, 402. The left jamb 401 is formed with a pair of prize windows 404, 405, whereas the right jamb 402 is formed with a pair of prize windows 406, 407. The strip décor 403 is formed with a bonus slot 408. Moreover, an animated object, which is a virtual dancer 409 in this embodiment, is disposed in the door frame 40 between the left and right jambs 401, 402.
The graphical user interface 200 further includes an odds table 29. The odds table 29 includes fifteen rows of five number spaces. Each of the rows of the odds table 29 is associated with a corresponding payout multiplier that is marked at a left end thereof. The payout multipliers decrease in a descending order of the rows. The graphical user interface 200 further includes a smaller virtual bingo card 30 having the same content as the virtual bingo card 28, a remainder column 31 showing remaining points of the player, a payout column 32 showing a payout amount to be awarded to the player, and a bet column 33 showing a bet placed by the player.
Next, referring to step 42 in FIG. 4, the player activates the main game by dropping in coins, a game card (prepaid card) or any other manner authorized by the gaming apparatus 2. Thereafter, referring to step 43 in FIG. 4, the player places abet (such as 5 points) through the BET key 24, operates the CHANGE key 25 to change the virtual bingo card 28, and operates the CONFIRM key 26 to select the desired virtual bingo card 28. Subsequently, referring to step 44 in FIG. 4, a winning area of the odds table 29, such as the tenth row of the odds table 29, is defined with reference to the bet placed by the player. Then, referring to step 45 in FIG. 4, a predefined winning bingo pattern, for instance, the four corners of the numerical bingo pattern, is shown on each of the virtual bingo cards 28, 30.
Subsequently, referring to step 46 in FIG. 4, the game processor 22 of the gaming apparatus 2 randomly draws a bingo number ranging from 1 to 75, fills in one of the number spaces of the odds table 29 with the drawn bingo number according to the drawing sequence of the bingo number, and marks the virtual bingo card 28 accordingly when the drawn bingo number is present in the numerical bingo pattern of the virtual bingo card 28. At the same time, referring to step 47 in FIG. 4, the game processor 22 constantly checks whether the predefined winning bingo pattern is formed on the marked virtual bingo card 28. Step 46 is repeated until the predefined winning bingo pattern is formed on the marked virtual bingo card 28.
When the predefined winning bingo pattern is formed, the player is required to operate the CONFIRM key 26 in step 48 in FIG. 4 to confirm the presence of the winning condition in accordance with game rules established in certain places. If the player presses the CONFIRM key 26 before a preset period (such as five seconds) expires, the flow goes to FIG. 6. Otherwise, the flow goes to FIG. 8.
In step 61 in FIG. 6, with reference to FIG. 7, three rows of the numerical bingo pattern of the virtual bingo card 28 are replaced by a multi-liner pattern to indicate the outcome of the main bingo game. Note, however, that the content of the smaller virtual bingo card 30 remains unchanged.
The multi-liner pattern includes a plurality of distinct images, such as a crown, a necklace, a bracelet, a belt, a figurine, a specter, etc. In this instance, the game processor 22 selects the crown, the necklace, the bracelet and the belt to form a set of virtual prizes of a first prize combination.
Step b): Awarding of a virtual prize
After step 61, the flow goes to step 62 in FIG. 6, where the game processor 22 determines whether the row that contains the winning bingo number is located in the predefined winning area of the odds table 29. In the example of FIG. 7, since the winning bingo number “14” is contained in the tenth row of the odds table 29, which is the predefined winning area, the game processor 22 deems the outcome of the main bingo game to match predefined first winning criteria for winning one of the first virtual prizes in the first prize combination.
When the main game outcome matches the first winning criteria, the flow goes to step 63 in FIG. 6, where the game processor 22 awards the player a randomly selected one of the virtual prizes in the first prize combination. As shown in FIG. 9, the awarded virtual prize is put on the virtual dancer 409. In the preferred embodiment, because the player received a virtual prize, the player is no longer awarded with a payout amount initially acquired in the main bingo game. Then, referring to step 64 in FIG. 6, the game processor 22 determines whether the player has collected all of the virtual prizes in the first prize combination. In the affirmative, the flow proceeds to FIG. 10 for playing a bonus game. Otherwise, the flow proceeds to FIG. 8.
In step 62, when the game processor 22 determines that the main game outcome does not match the first winning criteria, the flow goes to step 65 in FIG. 6, where the game processor 22 calculates a payout amount based on the bet placed beforehand by the player and the payout multiplier associated with the row of the odds table 29 that contained the winning bingo number. The flow then proceeds to FIG. 8.
Referring to step 81 in FIG. 8, the player is prompted to operate the CONFIRM key 26 so that the points in the payout column 32 are added to the points in the remainder column 31. Then, referring to step 82 in FIG. 8, the player is further prompted whether or not to terminate the progressive game. If it is desired to terminate the progressive game, the points in the remainder column 32 are printed out or stored in the game card of the player, and the game is ended. In the negative, the flow goes back to FIG. 4.
Step c): Repeating Steps a) and b) until the Player has Collected All of the Virtual Prizes in the First Prize Combination
When the flow goes back to FIG. 4, a new bingo game session begins. Thereafter, based on the outcome of the new bingo game, the game processor 22 determines whether or not to award the player one of the virtual prizes in the first prize combination in the manner described hereinabove. Note that, since the virtual prize awarded in step b) is randomly selected, it is possible that that the player will be awarded with a virtual prize that he or she had already collected. As a result, the player may have to play a large number of bingo game sessions before he or she is able to collect all of the virtual prizes in the first prize combination.
Step d): Playing a bonus game
As shown in FIG. 9, playing of the bonus game begins when the player has collected all of the virtual prizes in the first prize combination, i.e., when the virtual dancer 409 has put on all of the virtual prizes (i.e., the crown, necklace, bracelet and belt) in the first prize combination.
Referring to step 91 in FIG. 10, when the bonus game begins, the bonus prizes included in a second prize combination are arranged among the prizes windows 404, 405, 406, 407 of the jambs 401, 402. In this embodiment, the bonus prizes are predetermined points, such as 20, 50, 5 and 100 points. Then, referring to step 92 in FIG. 10, the virtual dancer 409 begins to dance and, as shown in FIG. 11, points to different ones of the prize windows 404, 405, 406, 407 using her hands within a predetermined time period, such as five seconds. Subsequently, in step 93 in FIG. 10, it is determined if the predetermined time period has expired. In the affirmative, the flow goes to step 94 in FIG. 10, where the virtual dancer 409 stops dancing, as best shown in FIG. 12. At this time, a selected one of the prize windows 404, 405, 406, 407 is that pointed to by the virtual dancer 409 at an instant the predetermined time period expired. Thereafter, with reference to step 95 in FIG. 10, the game processor 22 determines whether the prize window selected by the virtual dancer 409 is not empty, which is referred to herein as second winning criteria for winning one of the bonus prizes in the second prize combination. If the selected prize window is empty, the bonus game is terminated, and the flow proceeds to FIG. 8. Otherwise, with reference to step 96 in FIG. 10, the points (in this instance, 20) contained in the selected prize window (in the instance, the prize window 404) are awarded to the player, the accumulated awarded bonus points are shown on the bonus slot 408 and, as shown in FIG. 12, the selected prize window 404 is emptied. The flow then proceeds to step 97 in FIG. 10, where the game processor 22 determines whether all of the prize windows 404, 405, 406, 407 had been emptied. In the affirmative, since all of the bonus prizes in the second prize combination had been awarded to the player, the bonus game is terminated, and the flow proceeds to FIG. 8. Otherwise, the flow goes back to step 92 in FIG. 10 so as to give the player a chance to win another one of the bonus prizes.
Therefore, the first time the virtual dancer 409 selects one of the prize windows 404, 405, 406, 407, the player is guaranteed to win one of the bonus prizes. However, since the selected prize window 404, 405, 406, 407 will be emptied subsequently, the probability of winning another one of the bonus prizes will be lowered accordingly.
While the present invention has been described in connection with what is considered the most practical and preferred embodiment, it is understood that this invention is not limited to the disclosed embodiment but is intended to cover various arrangements included within the spirit and scope of the broadest interpretation so as to encompass all such modifications and equivalent arrangements.
