Three, four, or five scatter symbols will trigger 10,15, and 20 spins, respectively. A new symbol will join the reels during this bonus game, and if it does, it will take the values displayed on all fish symbols. If this symbol lands regularly, that’s a good way to build up wins. You will trigger 10 extra spins by landing four scatters on the reels during the feature, with up to three of these retriggers possible.
