These are the BONUS symbols. They can appear on reels 1, 3 and 5.
In the base game, on any spin, the MEDUSA SPIN feature can trigger. When that happens, all of the symbols depicting characters on reels 2, 3 and 4 transform into WILD symbols, substituting for all symbols except for BONUS and SUPER BONUS.
Hit 3 BONUS symbols to trigger the FREE SPINS feature and win 10 free spins. During the FREE SPINS round, when MEDUSA SPIN happens, all symbols depicting characters transform into WILD symbols and have a random multiplier assigned to them. If these WILDS are not used in the current spin, they stay on the screen until they are used in a later winning combination.
Whenever a multiplier of a WILD is used in a winning combinaton it is collected in a meter. All winning combinations are multiplied by this total multiplier.
Possible values for WILD multiplier symbols during the FREE SPINS round are: x2, x3, x4, x5 or x6. Hit 3 SUPER BONUS symbols during a MEDUSA SPIN to trigger the SUPER FREE SPINS feature and win 12 free spins. In the SUPER FREE SPINS feature, the chance to trigger the MEDUSA SPIN is higher and the WILD multiplier values are increased.
Possible values for WILD multiplier symbols during the SUPER FREE SPINS round are: x4, x5, x6, x7 or x8. Feature cannot be retriggered. Special reels are in play during the round.
