GAMING MACHINE WITH PRECURSOR AND SUPPLEMENTARY SYMBOL SET FEATURE

摘要

In one example, a method involves: a machine making a determination that a trigger event occurred; responsive to making the determination, (i) selecting a precursor symbol set from a precursor symbol group, and (ii) for the or each symbol in the selected precursor symbol set, randomly determining a corresponding arrangement position; displaying on a display the selected precursor symbol set by displaying the or each symbol in the selected precursor symbol set in the corresponding arrangement position for that symbol; selecting a supplementary symbol set from a supplementary symbol group; for the or each symbol in the selected supplementary symbol set, determining a corresponding arrangement position; and after displaying the selected precursor symbol set, displaying on the display (i) the selected precursor symbol set, and (ii) the supplementary symbol set by displaying the or each symbol in the selected supplementary symbol set in the corresponding arrangement position for that symbol.

1. A machine comprising: a display configured to display symbols in a game; a processor; and a non-transitory computer readable medium storing program instructions, that when executed by the processor, cause a set of functions to be performed, the set of functions comprising:
making a determination that a trigger event occurred; responsive to making the determination, (i) selecting a precursor symbol set from a precursor symbol group, and (ii) for the or each symbol in the selected precursor symbol set, randomly determining a corresponding arrangement position; displaying on the display the selected precursor symbol set by displaying the or each symbol in the selected precursor symbol set in the corresponding arrangement position for that symbol; selecting a supplementary symbol set from a supplementary symbol group; for the or each symbol in the selected supplementary symbol set, determining a corresponding arrangement position; and after displaying the selected precursor symbol set, displaying on the display (i) the selected precursor symbol set, and (ii) the supplementary symbol set by displaying the or each symbol in the selected supplementary symbol set in the corresponding arrangement position for that symbol.
