Abstract: A gaming device comprises a display, a processor, and a memory storing (a) a current symbol position state defining, for each of a plurality of columns of symbol positions, a number of symbol positions for which symbols are to be selected; (b) a pay table; and (c) instructions. When the instructions are executed by the processor cause the processor to control the display to display a plurality of columns of symbol positions corresponding to the current symbol position state, select symbols for the displayed symbol positions by selecting stopping positions of a plurality of reel strips, wherein at least one of the reel strips comprises at least one designated symbol, evaluate the selected symbols for winning combinations based on the pay table, and responsive to the selected symbols of a column including a designated symbol, modify the symbol position state for the respective column to include at least one additional symbol position for a next symbol selection.

Abstract: A method of conducting a wagering game includes: conducting a base game on an electronic gaming machine; detecting a first trigger condition in the base game; initiating a feature game in response to the first trigger condition; detecting a second trigger condition in the feature game; granting access to a plurality of bonus feature game levels in response to the second trigger condition; and determining an outcome of the feature game.

Abstract: An electronic gaming machine includes a display in the form of a matrix of rows and columns and a controller configured to conduct a game instance upon receiving a wager via a player input. In conducting each game instance, the controller activates a number of columns on the display based on the wager and controls a display to indicate which columns in the display have been activated. The controller determines if any of the activated columns meets a triggering condition and controls the display to display the activated columns which meet the triggering condition with a modified background. The controller then determines an outcome of the game instance based on whether a predetermined number of activated columns which meet the triggering condition are adjacent one another and makes an award to the player based on the outcome of the instance.
