CONTROLLING VOLATILITY AND RETURN TO PLAYER IN EXPANDED HOLD-AND-SPIN FEATURES

A hold-and-spin feature is expanded and a potential game outcome is increased by triggering resetting of the remaining number of spins to different reset spin values based on the collection of a number of first respin triggering symbols. In order to control and manage the degree of randomness in having different numbers of reset spin values, and thus controlling game volatility and/or thus maintaining a target RTP, multiple reel strip types with different properties are used to select symbols for various positions in the symbol matrix. The multiple reel strip types may have different probabilities of selecting credit symbols, non-credit symbols, first respin triggering symbols, second triggering symbols, and so on.
