Feature symbols simply refer to those that carry special powers in the game. In our case, slot machine Great Blue has two feature symbols, which include the wild and scatter.

The wild symbol is depicted by the ‘Great Blue’ Dolphin. Landing five of these symbols on an active payline will award you with the highest possible payout of 10,000 coins.

When it’s not working on awarding you the top prize, it plays the role of an ordinary wild, substituting for all the other regular symbols to form the best winning combination. The only symbol that cannot be replaced by the wild is the scatter. The wild will also double all the wins that it manages to complete.

The scatter symbol, on the other hand, is represented by the pear inside the pink oyster. Like the majority of the other scatter symbols, you need to land at least three symbols anywhere on the 1st, 3rd, and 5th reels to trigger the free spins game. Other than this, there’s no other special role that the scatter plays.

Seashells Free Spins Bonus Game

As we’ve already mentioned, the free spins game is triggered by landing three or more scatter symbols anywhere on reels 1, 3 and 5. Once active, you enter the seashells bonus game, where you are awarded a 2x multiplier and 8 free spins. After that, you progress to the mini-game where you are required to pick 2 out of the readily available 5 seashells. Depending on your choice, you could win yourself multipliers of up to 15x your bet or free spins that amount to 33 spins.

It gets better if you manage to land at least three more scatters as the free spins game is re-triggered. Your reward will be 15 extra spins that are played using the same multiplier as the spin that activated it.
