Abstract: A gaming system displays a first array of symbols and a second array of symbols for a wagering game. The second array of symbols includes at least one second-array reel. The at least one second-array reel includes a predetermined sequence of symbols. The at least one second-array reel rotates the predetermined sequence of symbols to determine at least partially the second array of symbols. The second array is divided into at least two sub-arrays, the at least one second-array reel extending into the at least two sub-arrays. A controller selects at least one symbol from the first array and copies the at least one selected symbol into one or more positions in each of the at least two sub-arrays. The at least two sub-arrays is displayed with combinations of symbols including the at least one selected symbol. The controller evaluates the combinations to determine an outcome to the wagering game.

Abstract: A gaming system includes an input device, a display device, a processor, and a memory device. The memory device stores instructions that, when executed by the processor, cause the gaming system to receive a wager and to display an array having a plurality of symbol positions, each of the symbol positions being populated by symbols located on a plurality of symbol-bearing reels. The reels spin and stop to place symbols on the symbol-bearing reels in visual association with symbol positions of the array. At least one extended symbol indexed on a first reel visually overlaps one or more symbols on an adjacent second reel (a) as the first reel spins the extended symbol through the array and (b) without affecting a stopping position of the adjacent second reel. An award is awarded for any winning combinations defined by the symbols in the display area.

Abstract: A method for enabling a portal game on a wagering game device includes the acts of using a processor operatively associated with the wagering game device to conducting a wagering game on the wagering game device in accord with a first math model and using a portal game controller, which may be the processor operatively associated with the wagering game device or a separate controller, operatively associated with both the portal game and the wagering game device, to overlay a portal game over the wagering game. The portal game includes a second math model that is mathematically independent from the first math model of the wagering game.

Abstract: A community game having a “winner-takes-all” feature in which at least one eligible proxy winning player of a round of the community game, which is initiated by a triggering event and is played by multiple players at linked gaming terminals, accrues the highest award among the awards accrued by other proxy players of the community game. The winning proxy player must satisfy an eligibility criterion to participate in the community game and to be eligible to receive the winner-takes-all award, which includes all of the awards accrued by the winning eligible proxy player during one or more rounds and at least the other respective awards accrued by the other proxy players during the round(s). These awards can include those accrued by non-eligible proxy players as well, who are awarded nothing at the end of the round(s). Non-winning eligible proxy players of the community game are awarded whatever awards they accrued during the round(s).

Abstract: A wagering game system configured to conduct a wagering game includes a wagering game that itself includes at least one display device and at least one user input device, as well as one or more processors operatively associated with the wagering game machine. The one or more processors are configured to perform, responsive to instructions stored on one or more physical memory devices, the acts of randomly determining an outcome of a base wagering game, determining if a trigger condition for a skill-based game feature is satisfied by the outcome of the base wagering game, providing an option to accept the skill-based game feature or to decline the skill-based game feature in favor of a non-skill-based game feature, and executing the skill-based game feature responsive to an instruction to accept the skill-based game feature.

Abstract: Gaming devices, gaming systems, methods of conducting a wagering game, and computer programs for initiating a wagering game are presented herein. A gaming system is presented that includes a wager input device, a display, and a controller. The wager input device receives wagers from players to play the wagering game. The display displays outcomes of the wagering game. Prior to displaying the outcome of the wagering game, the controller determines whether to add at least one symbol clump to at least one of a plurality of reels. A symbol clump comprises one or more identical symbols occupying two or more symbol positions located immediately adjacent one another on one reel. In response to a determination to add at least one symbol clump, the controller instructs the display to visually indicate the addition of the symbol clump to the reel, and to display the outcome of the wagering game.
