The offered free spins can be super free spins, monster spins, mega spins, or regular free spins and the difference is generally determined by the bet value of the free spins. While super free spins usually have a bet value from $1 to $10, the bet value of “normal” free spins is usually from $0.10 to $0.40, which makes it possible for casinos to give them out in bigger batches than high-value spins.
