Submariner Bonus Features
Yes, this is a treasure-hunting expedition, but this game also offers features worthy of an Arkansas progressive jackpot fan. Why? Let us explain. Free spins arrive when four or more Scatter Boy icons appear, offering at least 10 spins and the possibility of extra triggers during that phase. Each spin lifts your multiplier, inching from a modest 2x up to a noteworthy 30x.
Meanwhile, any successful cluster disappears, letting new symbols fall and possibly chain multiple wins in a single round. This approach ensures no two spins feel the same. When a flurry of combos hits, you’ll see your balance perk up. If you like the idea of lively marine-themed adventures with increasing excitement, Submariner suits that desire perfectly!
