Abstract: In a gaming machine for playing a base game having a feature game with multiple levels: receiving a wager from a player for playing four instances of the base game, where the wager is deducted from a credit balance established by the player. Symbols for each of the four instances of the base game may be selected and displayed, where each instance displays the selected plurality of symbols in a matrix of display positions. The feature game may be initiated when the selected plurality of symbols includes a feature game trigger, where the feature game comprises a plurality of free plays of a number of instances of the base game based on a level of the feature game as determined by the feature game trigger, and the number of instances is one if the level is normal, four if the level is super, and eight if the level is extreme.

Abstract: Systems and methods of electronic gaming are disclosed. In various embodiments, a gaming system may implement a method for electronic gaming, which may comprise receiving a credit wager to initiate play of a game, selecting a plurality symbols from a plurality of reel strips stored in the memory, displaying the selected plurality of symbols in a plurality of adjacent columns of symbol display positions, dividing the symbol display positions in each of the plurality of columns into a first subset of symbol display positions and a second subset of symbol display positions, determining whether an evaluation change condition has been met with respect to a column in the plurality of columns, a first game evaluation based upon the evaluation change condition, and performing a second game evaluation based upon the evaluation change condition.

Abstract: Systems, methods, and articles of manufacture for electronic gaming are disclosed. In a first aspect, a gaming system may implement a method of electronic gaming. The method may include receiving a credit wager to initiate play of a game, selecting a plurality of symbols, and displaying the selected symbols in a plurality of columns, where each column in the plurality of columns includes a plurality of symbol display positions. The method may further include determining that the selected symbols in at least one of the plurality of columns collectively satisfy a first jackpot award condition associated with a first jackpot award, determining that the selected symbols in at least one of the plurality of columns of symbol display positions collectively satisfy a jackpot multiplier condition associated with a jackpot multiplication factor, and generating an award based upon the first jackpot award and the jackpot multiplication factor.
