Description

    FIELD OF THE INVENTION
  • The subject invention relates to gaming machines, and more particularly, to a gaming machine having a bonus game. [0001]
  • BACKGROUND OF THE INVENTION
  • Electro-mechanical slot machines are well known in the art. Mechanical reels include symbols on their reel strips and are driven by stepper motors to rotate and stop, thereby presenting symbol combinations on one or more pay lines. Depending on the pay line(s) symbol combinations, the player has one or more winning combinations or losing combinations. For winning combinations, the player receives an award based upon an established pay schedule (referred to as the “pay table”). [0002]
  • Modernly it has been known to provide a secondary bonus screen for electromechanical slot machines, embodied, for example, as a plasma screen disposed apart from the game display. Based upon a triggering event, the bonus screen selects a bonus for the player. [0003]
  • In addition to the electromechanical slot machines, video slot machines are well known and are quite popular with players. In a basic form, the player makes a wager to play the game and enables one or more pay lines on a video display. Upon prompting play, a processor selects and displays game symbols on the display in a matrix form. The symbols on any enabled (selected) pay line are compared to the established pay table of winning outcomes to determine if a winning or a losing outcome have been obtained. Where a winning outcome is obtained the player receives an award based upon an established pay table for the game. The player then makes another wager, enables one or more pay lines and plays another game (often referred to as a “hand” or “spin”). [0004]
  • In either the electromechanical or video slot machine games, it is known to provide the player with a predetermined number of free games or spins, without requiring a new wager, based on one or more triggering outcomes. These are generally known as bonus games. [0005]
  • To make such video games more entertaining, it is known to provide certain configurations of bonuses. The bonus may be triggered by a certain combination of symbols on a pay line or scattered on the display (a “scatter” bonus) during the play of the base game. It is also known to provide secondary screens for issuing a bonus. That is, when the player obtains a certain, predetermined outcome during play of the base game, the game processor displays a secondary screen where the player can select from certain options to obtain the bonus. For example, in one game, the player selects, via a touch-screen from between several displayed “pigs”, the selected pig, in an animated fashion, revealing the bonus. The bonus can be a fixed amount, usually a function of the amount wagered, or a multiplier, which is multiplied by the amount wagered to determine the amount won. [0006]
  • Many of these games are themed and the symbols and bonuses are configured to be consistent with the theme of the game. [0007]
  • The bonus game is designed to attract and retain a player's attention and thus increase the amount of time spent at a particular game. New games are continuously being produced, while older games are being replaced. Thus, to extend the life of a game, the bonus game must be able to grab a player's attention and to keep the player interested over a longer period of time. [0008]
  • The present invention is aimed at one or more of the problems identified above. [0009]

The pay out device 18, as is known in the art, may be embodied as a hopper to receive and dispense coins/tokens, means for accumulating game play credits, a device for writing to a credit voucher, credit card device or the like.
  • In an illustrated embodiment, the gaming machine [0036] 10 is adapted to play a game entitled “Winny™”, which has a theme based around the title character, Winny™. The Winny™ game includes a base game and a bonus game, as described below. However, it should be noted that the gaming machine 10 may be adapted to implement other games having different themes, in accordance with the present invention.
  • With reference to FIG. 2, the gaming machine [0037] 10 includes a controller 20 which controls the display 12 and the play of the game in response to input from a player. In one embodiment, the controller 20 includes a microprocessor based central processing unit or CPU 22 and a first data structure 24. In one embodiment, the first data structure 24 may be embodied as any suitable memory device including a random access memory (RAM), an EEPROM, compact disk, flash card or compact flash card, and/or other suitable memory device. As shown, the display 12, wager accepting device 16, and the pay out device 18 are coupled to the central process unit 22.
  • During the base game, the controller [0038] 20 working in conjunction with the wager accepting device 16, detects when a player has inserted a number of coins or credits. Then the controller 20 operates to execute the base game in accordance with a base game program stored in the first data structure 24.
  • With reference to FIG. 3, in the illustrated embodiment, as discussed above, the present invention may be embodied in a game entitled, “Winny™”. Winny™ is a five-reel slot game with 9 pay-lines. Each reel includes three positions. [0039]
  • As discussed above, the display [0040] 12 is a touch screen display. A game play area 26 is displayed during the base game which game elements, displays and screens for pay are displayed as well as areas to impart information to the player during play and for the player to input data to the controller 20 (FIG. 2). Certain of these areas are allocated for display purposes only and do not provide for touch screen input to the controller 20. For example, a credit area 28 displays the total amount of accumulated credits for play of the game, a total bet area 30 displays the total amount of a player's current wager, a won area 32 displays the total amount won for the hand or spin of the game and a pay area 34 displays the corresponding amount paid to the player in coins, tokens, or credits, for a winning outcome in the base or bonus games (see below).
  • Additionally, a select lines area [0041] 36 displays the number of enabled pay lines being played by the player and a bet per line area 38 displays the amount of credits wagered per enabled pay line. In one embodiment, the select lines area 36 and the bet per line area 38 are touch screen button, which when actuated, toggle through the select line and bet per line options, respectively.
  • In addition to the foregoing areas, certain portions of the game play area [0042] 26 define input buttons for inputting information to the controller 20 for controlling the game (FIG. 2). Actuation of a pay table button 40 displays various information to the player related to the various winning outcomes and the pay or award for each. Actuation of a help button 42 displays various help information to the player, such as game instructions. Actuation of a cash out button 44 results in the issuance of the amount of accumulated credits amassed during the game to the player. Other action and control buttons may be provided as is known in the art.
  • The controller is configured to display in the game play area [0043] 26, a primary game matrix 46 of coordinates shown for purposes of this description as a three-by-five matrix 46. During play, game elements (as described below) are selected and displayed in each coordinate of the matrix 46. As shown in FIGS. 1 and 3, the matrix 46 may be displayed in a fashion of five simulated slot machine reels 48A, 48B, 48C, 48D, and 48E which correspond to the five columns of the matrix 46. Each reel 48A-48E includes three coordinates defining the game matrix 46.
  • When play of the (base) game is prompted by the player touching a spin button or maximum bet button [0044] 15 (in FIG. 1), the controller 20 (FIG. 2) selects and displays data from the first data structure 24 (FIG. 2) representing various game elements to be displayed to define one or more outcomes for the play of a game hand or spin. The selection of the game elements is based, for a casino game, upon a random number generator (RNG). Game element data is stored and/or selected based upon a predetermined distribution such that each game element has a predetermined statistical probability of being selected as is known in the art. When the game elements are selected they are displayed in the coordinates of the matrix 46. The controller 20 (FIG. 2) may be configured to simulate rotation of the reels 48A-48E in advance of the display of the game elements.
  • As shown in FIG. 3, the controller [0045] 20 (FIG. 2) is configured to display various pay lines 47 for the matrix 46. As is know, the game may include ten or more or less pay lines. Generally, the pay lines include horizontal and/or diagonal line segments having a single coordinate per each reel 48A-48E. In a manner known in the art, the display 12 may be configured to display either or both the selected pay lines and the number of credits wagered per line. During the base game, an award is given to the player when predetermined winning combinations of the game elements 50 appear on an enabled pay line, in a manner well-known in the art.
  • With reference to FIG. 4, the first data structure [0046] 24 (FIG. 2) includes data representing the plurality of game elements 50, which in the illustrated embodiment, includes elements 50A-50M. The random number generator and the first data structure 24 (FIG. 2) cooperate to provide for the random selection and assignment of the game elements 50 into the coordinates of the game matrix 46 for the base game to define, along each player enabled pay line, a winning or losing outcome. Based upon the distribution of the game elements 50 in the first data structure 24 (FIG. 2), each predetermined winning combination has a predetermined, statistical probability of being selected as well as an assigned pay (award) for each to define the overall pay, or conversely “hold”, for the game. If a player obtains a winning symbol combination on one or more enabled pay lines, the controller 20 (FIG. 2) issues a base game award in the form of credits, tokens, coins, or the like.
  • In addition to the base game, in the present embodiment of the game machine [0047] 10, three bonus games are provided. Each bonus game is entered when a predetermined, corresponding triggering event occurs during the base game. Generally, one or more game elements 50 or combinations of game elements 50 are defined as triggering event. For example, one type of triggering event is known as a “scatter bonus” or “scatter pay”. A scatter bonus is typically defined as the occurrence of a predetermined number, e.g., three, of one of the game elements 50 anywhere on game matrix 46. Another type of triggering event is defined as the occurrence of a predetermined number of one of the game elements 50 in predetermined locations on a pay line or pay lines, e.g., the pay lines enabled by the player.
  • The first bonus game is entered when a first predetermined triggering event occurs. During the base game, the controller [0048] 20 identifies an occurrence of the first triggering event during the base game and responsively enters the first bonus game. The first triggering event is defined by a predetermined number of a bonus game element, e.g., 50F, appearing on the display 12 during the base game. The controller 20 prompts the player to select one of the bonus game elements 50F in response to the triggering event, randomly determines a bonus game multiplier in response to selection of one of the bonus game elements, and awards the playing a bonus as a function of the bonus game multiplier.
  • With reference to FIGS. 5 and 6, an example of the first bonus game, as implemented in the Winny™ game, is illustrated. In FIG. 5, an example of a first triggering event or first bonus game triggering event, is defined as the occurrence of at least a predetermined number, e.g., [0049] 3, of a “snow globe” game element 50F in any of the cells of the matrix 46. It should be noted that although the snow globe elements 50F are shown on a horizontal pay line, the first triggering event in the illustrated embodiment, is a scatter trigger, i.e., the first bonus game is triggered when a predetermined number (or more) of the snow globe element 50F occur in any cell. When the first triggering event occurs, the snow globe game elements 50F are animated to signify entering the first bonus game.
  • In one embodiment, the bonus is determined as a function of a plurality of pay tables. Each pay table corresponds to the actual number of bonus game elements on the display. For example, in the illustrated embodiment, the first bonus game is triggered when three, four, or five snow globe game elements [0050] 50F appear during the base game. The game includes first, second, and third pay tables corresponding to three, four, or five snow globe game elements 50F. Each pay table has a plurality of bonus game multipliers. The controller 20 randomly selects the randomly determined bonus game multiplier from the corresponding pay table. Within each pay table, each bonus game multiplier has an associated probability. For example, each pay table may include three to five possible bonus multipliers each with an equal probability. An example pay table is shown below.
    TABLE 1
    Number of Snow Globe
    Game Elements 3 4 5
    First Globe Multiplier 2 3 20
    Second Globe Multiplier 3 4 35
    Third Globe Multiplier 4 5 50
    Fourth Globe Multiplier 8 65
    Fifth Globe Multiplier 80
  • The bonus is determined as a function of the randomly determined bonus game multiplier and the number of credits wagered by the player. For example, the bonus may be equal to the number of credits wagered by the player multiplied by the randomly determined bonus game multiplier. [0051]
  • In one embodiment, when the first bonus game is entered, the corresponding pay table is selected (based on the actual number of snow globe game elements [0052] 50F) and each bonus game multiplier in the corresponding pay table is assigned to one of the snow globe game elements 50F. In another embodiment when the first bonus game is entered, the corresponding pay table is selected (based on the actual number of snow globe game elements 50F). When the player selects one of the snow globe game elements SOF, a bonus game multiplier from the corresponding table is randomly selected.
  • With reference to FIG. 6, a method [0053] 52, according to an embodiment of the present invention, operates a gaming machine 10 for playing a game. The game includes a base game and a bonus game. In a first process step 54, a plurality of game elements 50 are displayed during the base game. In a decision step 56, if the first triggering event has occurred, i.e., 3 or more snow globe game elements 50F, then the game proceeds to a second process step 58. If the first triggering event has not occurred then the game proceeds back to the first process step 54.
  • In the second process step [0054] 58, the first bonus game is entered. In a third process step 60, the player is prompted to select one of the bonus game elements in response to the first triggering event. In a fourth process step 62, a bonus game multiplier is randomly determined in response to selection of the bonus game element. In a fifth process step 64, the player is awarded a bonus as a function of the bonus game multiplier.
  • The second bonus game is entered when a second predetermined triggering event occurs. During the base game, the controller [0055] 20 identifies an occurrence of the second triggering event and responsively enters the second bonus game. The second triggering event is defined by a predetermined number of a bonus game element appearing on the display 12 during the base game. The controller 20 displays a plurality of bonus game items on the display 12, prompts the player to select a predetermined number of the bonus game items, randomly determines a total bonus game multiplier in response to selection of the predetermined number of bonus game items, and awards the player a bonus as a function of the total bonus game multiplier.
  • In one embodiment, each of the selected bonus game items has an associated bonus game multiplier and the total bonus game multiplier is the sum of the bonus game multiplier associated with of the selected bonus game items. [0056]
  • In one embodiment, the bonus is determined as a function of a plurality of pay tables. Each pay table includes a plurality of bonus game multipliers. Each bonus game multiplier has an associated probability. For example, each pay table may include seven possible bonus game multipliers, each having a probability of one-seventh. [0057]
  • In one embodiment, the second bonus game has first and second pay tables. The first pay table has a probability of two-thirds and the second pay table has a probability of one-third. When the second bonus game is entered, one of the first and second pay tables is randomly selected. In one embodiment, after the one pay table is selected each of the possible bonus game multipliers is randomly assigned to one of the bonus game items. In another embodiment, one of the possible bonus game multipliers is randomly selected after the player selects one of the bonus game items. In the latter embodiment, after a bonus game multiplier has been selected and assigned to a player selected bonus game item, it becomes unavailable for future selected bonus game items. [0058]
  • The total bonus game multiplier is the sum of the bonus game multiplier assigned to each selected bonus game item. In one embodiment, the bonus is determined as a function of the total bonus game multiplier and a number of credits wagered by the player. For example, the bonus may be equal to the number of credits wagered by the player on the winning pay line multiplied by the total bonus game multiplier. [0059]

  • The bonus is determined as a function of a plurality of pay tables, each pay table having a plurality of bonus game multipliers. Each pay table has a probability associated with each bonus game multiplier. [0067]
  • In one embodiment, the number of swings at the piñatas is one of two, three and four swings. When the third bonus game is entered, the number of swings (two, three, or four) is randomly selected. The third bonus game has first, second, and third pay tables, corresponding to two, three, or four swings. Each pay table has a plurality of possible multipliers, e.g., eight multipliers. Each of the possible multipliers has an associated probability, e.g., one-eighth. [0068]
  • In one embodiment, after the number of swings is randomly selected each of the piñatas is randomly assigned one of the possible bonus game multipliers. In another embodiment, one of the possible bonus game multipliers is randomly selected after the player selects one of the piñata. In the latter embodiment, after a bonus game multiplier has been selected and assigned to a player selected bonus game item, it becomes unavailable for future selected bonus game items. [0069]
  • The total bonus game multiplier is the sum of the bonus game multipliers associated with each of the selected piñatas. The bonus is determined as a function of the total bonus game multiplier and a number of credits wagered by the player, e.g., the bonus may be equal to a number of credits wagered by the player on a winning pay line multiplied by the total bonus game multiplier. [0070]
  • With particular reference to FIG. 10, an example of the third triggering event, as implemented in the Winny™ game, is defined as the occurrence of a predetermined game element, a “Swatta Piñata” game element [0071] 501, in the last three positions of a selected pay line.
  • After the third triggering event occurs, the player is presented with three game items: a golf club, a maraca, and a guitar (not shown). The player is then prompted to chose one of the items, in this example, a golf club. With particular reference to FIG. 11, after the player chooses one of the items, third bonus game screen [0072] 74 is displayed in the game screen area 26. The third bonus game screen 74 depicts Winny™ and a plurality of piñatas 78. Winny™ 68 is holding the chosen item, shown as a golf club 76.
