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.
