Abstract
An electronic gaming machine includes a processor configured to control a display device to display a plurality of columns of symbol positions, where each symbol position includes a symbol selected from a set of symbols. The processor is also configured to determine whether any of the symbol positions include a designated symbol, and if so, to: i) control the display device to hold the designated symbol in the symbol position for at least one subsequent game instance of a series of game instances, and ii) increase a multiplier used in determining a game award from a first multiplier to a second, larger, multiplier. The processor is also configured to evaluate the symbols included in each symbol position to determine whether a winning combination of symbols is displayed. If a winning combination of symbols is displayed, the processor also calculates a game award using one of the first multiplier or the second multiplier.
