Gaming machine including win chains

摘要

A gaming machine has a standard game play mode, and a bonus feature game play mode. The bonus feature mode includes a win chain counter having an integer value. During standard game play mode, the user interface randomly displays a matrix of symbols and the computer calculates the wins based on the matrix of symbols. On appearance of a predetermined number of scatter symbols, bonus feature play commences and a the win chain counter is initialized. During bonus feature play, a winning spin initializes a first win chain, and a first non-winning spin decrements the win chain counter value, after a first win chain is initialized, and prior to a non-winning spin, winning spins are added to the first win chain. Subsequent win chains are generated and terminated by a non-winning spin until the win chain counter is decremented to zero. Then bonus feature game play terminates.
