     DETAILED DESCRIPTION 
       [0014]    The invention is generally directed to methods for playing and providing wagering games that include bonus or secondary game features and systems that are configured to provide for the interactive play of such wagering games. 
         [0015]    In the illustrated embodiment, a gaming machine  10  has a main display  12  and a user interface  14 . Interface  14  may be wholly or partially included in display  12 , particularly if display  12  is a touch-enabled or touchscreen device. The user interface  14  may alternatively include one more buttons, card reader, bill reader, or other devices which enable a player to operate and interact with machine  10 , including placing wagers, actuating game features and receiving credits, among other things. Machine  10  may also include additional displays, processing devices, programs, random number generating devices, a slot machine interface board (SMIB), memory, data input and output devices, and other components as necessary. For purposes of illustration, gaming machine  10  includes a data input/output or communication device  16  which is capable of communicating with display  12 , a processor  18  and memory  20 . Memory  20  may contain programs and information regarding the main and/or bonus game play which is processed by processor  18 . Generally speaking, gaming machines  10  are known in the prior art and are therefore not discussed in further detail. 
         [0016]    Alternatively, the gaming machine  10  may be a desktop computer, laptop or notebook computer, cell phone or other computing or mobile device which allows the player to place wagers and play the game. Such gaming machines  10  may be connected to a server computer or remote computer (not shown) to facilitate the wagering aspect of the present invention. The user interface  14  will depend on the type of gaming machine  10 , and may include without limitation, buttons, touchscreens, a keyboard and/or a keypad. 
         [0017]    In one aspect of the invention, the game has a main game and a bonus game. For example, the gaming machine  10  constructed may be an electronic gaming machine  10  which provides a main game on the main display  12 . In one embodiment, the main game primarily involves a video slot game, that is, a game in which there is a virtual depiction of slot machine reels spinning on display  12  as in a slot machine with mechanically operating reels. However other types of main games, such as a video poker, blackjack, roulette, baccarat, or the like, may also be provided and operate in accordance with the invention as described in this embodiment. 
         [0018]      FIG. 2  illustrates a method  50  configured in accordance with the invention to be provided by a gaming machine such as gaming machine  10 . As shown in step  52 , the player enters or otherwise places a wager and actuates the main game, typically through the selection of a button or use of the touchscreen portion of interface  14 . 
         [0019]    A bonus triggering event is configured to randomly occur in the main game, which may be governed by a random number generator used to generate outcomes of the main game or a separate random number generator, which may be based on coin-in values. A presentation may be provided on display  12  to indicate to the player that the bonus event has been triggered. Step  54  presumes the bonus game event is triggered in the main game. 
         [0020]    In some embodiments, the bonus game may actuate automatically. In other embodiments, the bonus game actuates upon a player interaction with interface  14 . In any embodiment, the bonus game actuates as shown in step  56  and a randomly determined bonus prize is indicated in step  58  on display  12 . 
         [0021]    The prize may be a monetary amount, gift or numerical multiplier for credits. The prize may also include an actuator for replaying the bonus game, receipt of which may be indicated to the player on display  12  through a unique presentation or symbol. As shown by step  60 , should there be no bonus actuator received in the bonus game, then the bonus received, if any, is distributed to the player in step  62 . A bonus prize of some kind may always be received in each bonus game in some embodiments. 
         [0022]    In this embodiment, a bonus game replay actuator may be received with a bonus prize, and may be derived by a separate random number generator, such that it may be randomly determined and indicated in connection with any randomly determined bonus prize possible in the bonus game. 
         [0023]    As shown by step  60 , if the bonus game replay actuator is received then another bonus game is actuated in step  56 . Method  50  continues and the bonus prize is randomly determined and indicated in step  58 , and cumulatively added with the prior bonus won until the bonus game replay actuator is no longer received and the bonus prizes are distributed in step  62 . 
         [0024]      FIG. 3  provides an exemplary machine  110  with bonus game screen  122  on display  112  in which a player receives a bonus prize of “100” with a bonus game replay actuator symbol  124 , indicating that the bonus prize of 100 is the multiplier of 25 credits. As shown by  126 , which may be a button configured for actuating the additional bonus game. The bonus game is then replayed and another bonus is determined. In some embodiments, the bonus reel as shown in  FIG. 3  may be stopped or appear to be stopped by player interaction with the bonus game through interface  114 . 
         [0025]    Method  150  illustrates another embodiment of the invention. A wager in the main game is received in step  152  and a bonus game is triggered and actuated in steps  154  and  156 , respectively. In step  158  the bonus prize is indicated. 
         [0026]    In step  160 , if the bonus game replay actuator not received, the bonus prize, if any, is distributed in step  162 . However, if the bonus game replay actuator is received, then as shown in steps  164  and  166 , a query is made to the player, which may be via display  12 , as to whether the player wishes to replay the bonus game or receive the bonus. The player may respond through player interface  14 . Should the player wish to keep the bonus rather than replay the bonus game, the bonus is distributed as shown by step  162 . Should the player wish to replay the bonus game, then the bonus game is replayed and actuated in step  156 , and the resulting bonus is indicated in step  158 . 
         [0027]    In some embodiments, the player is only provided with the opportunity to replay the bonus game for a preset number of rounds. Thus, after reaching the preset number, the bonus actuator will be removed from the possible outcomes in the bonus game. In the embodiments discussed herein, the bonus replay actuator results in another randomly-determined bonus prize which is provided to the player in lieu of the prior bonus prize as indicated to the player. In other embodiments, the bonus replay actuator results in a cumulative bonus prize which is added to any prior bonus prize randomly determined and received prior thereto. It should be readily apparent that the bonus prizes may be the same or differ, prior to and after replay is actuated. Also, the bonus game may be the same or differ. In other words, the player may be queried in step  64  as to whether they wish to play the same bonus game over or try their luck at another bonus game which differs from the first. While the second bonus game may visually differ from the first, the odds of winning certain bonuses may be the same of different as the first game. bonus game. 
         [0028]      FIG. 5  provides an exemplary machine  210  with bonus game screen  222  on display  212  in which a player receives a bonus prize of “100” with a symbol  224 , indicating that the bonus prize of 100 is the multiplier of 25 credits. A player is given the option to either accept the bonus by pressing  226 , in which case the bonus game ends, or replay the bonus game by pressing  228 , in which case a new bonus game is played and prize is randomly determined which will be indicated on screen  222 . 
         [0029]    In some embodiments, the invention is directed to an electronic gaming machine, such as a slot machine, including various components, such as a display device, memory, processor, random number generator, data input device, currency detector, card reader, etc., mounted in a housing. However, it is within the spirit and scope of this invention to utilize the methods described herein in other ways, such as for example, via online gaming sites, networked systems, personal computers or mobile devices. 
         [0030]    In some embodiments, the invention is directed to an electronic gaming machine having a display device and a game control device operatively associated with a memory and configured to control images displayed on the display device. The game control device provides for interactive play of a main or underlying wagering game including generating the display of one or more random events on the display device, among other things, wherein a prize is awarded if a random event matches one or more preset winning criteria. 
         [0031]    In some aspects of the aforementioned embodiments, the game control device further provides for the play of a secondary or bonus game. The secondary or bonus game may be actuated upon the satisfaction of one or more preset criteria. The one or more preset criteria may be satisfied by a random determination made at specific intervals or actuated by a triggering event. The triggering event may be related to, or a function of, the occurrence of one or more events in the underlying game. The one or more events which are associated with the triggering event may be preset prior to play of the game or randomly selected during play of the game. For example, the preset criteria may relate to the occurrence of a particular random event during play of the underlying game, such as the appearance of particular symbol. 
         [0032]    In some aspects of the aforementioned embodiments, the system is configured to provide a bonus game upon detecting the occurrence of a randomly triggered event in the underlying game which satisfies the bonus game criteria. The bonus game may require additional credits or currency or be freely provided at no extra cost to the player playing the underlying game. The triggering event for the bonus game may or may not also correspond to a winning event in the underlying game. 
         [0033]    In some embodiments, the bonus game involves the presentation of at least one spinning prize reel on the display device that includes a plurality of symbols wherein each symbol is associated with a winnable prize. In some embodiments, some player interaction received by the system, such as touching a button or portion of a touch-enabled display device, causes the spinning prize reel to appear to spin and stop upon a particular symbol associated with a specific prize. The prize may include anything of value, such as one or more goods or services, currency or credit, a jackpot, one or more free games, repeat wins or some other feature. 
         [0034]    In some embodiments, the player may choose whether to receive the specific prize or spin the prize reel again to attempt to achieve a different prize. Alternatively, the player may be offered the opportunity to select from a plurality of prize reels. The prize may comprise a retrigger event, that is, wherein the player is provided one or more additional chances to spin the reel, win additional free games or is provided with the opportunity to win a different or additional prize through another feature or bonus game, which may be the same or different from the spinning prize reel described herein. 
         [0035]    In some embodiments, the player may be provided with the ability to stop the prize reel after the prize reel begins spinning through a player input device or touch screen display device. The stopping action may be associated with player input, in that the prize reel stops when the player input is detected or within a short period of time thereafter. In other embodiments, the stopping action may be unrelated to the ultimate outcome of the prize reel in that the determination of the symbol (and thus, the prize) has been randomly determined upon receiving the player input that caused the reel to appear to spin. 
         [0036]    Those skilled in the art will readily appreciate that the methods described herein may be incorporated in a system in accordance with the invention using virtual representations of game features such as spinning reels, buttons, symbols and animated objects. The system of the invention may include various computer and network related software and hardware, such as programs, operating systems, memory storage devices, input/output devices, processors, servers with links to data communication systems, wireless or otherwise, and data transceiving terminals, and may be a standalone device or incorporated in another platform, such as a mobile device. Those skilled in the art will further appreciate that the precise types of software and hardware used are not vital to the full implementation of the methods of the invention so long as players, users and/or operators thereof are provided with useful access thereto and the opportunity to play the game as described herein.
