The Scatter symbol is your ticket to the buried treasure, when three or more Scatters land anywhere on the reels, you get to choose between three different free spin features that have their own special perks.
There are three different sets of free spins to choose from:
The Fairy Feature awards 7 free spins, with random wilds. Each spin will be visited by a fairy and given between 2 and 5 overlay Wilds placed on the reels in random positions.
The Mermaid Feature awards 10 free spins with a win multiplier. All wins are multiplied by 2 unless the win combination contains 1 or more Wild symbol, then the wins are instead multiplied by 4.
The Pirate Feature awards 15 free spins. In the Pirate Feature, wins are calculated on the number of visible symbols on the reels instead of on winning bet lines; meaning that the symbols do not need to appear on consecutive reels. For example, if there are 4 of the same symbol visible anywhere on the reels this pays the same as if there are 4 of the same symbol on a winning bet line in the main game. There are no Wilds on the reels during the Pirate Feature, but with 15 spins of this feature you can surely fill up your chest.
When 2 Scatter symbols appear anywhere on the reels you are awarded 1 free Feature Spin with a randomly chosen feature. Basically this is a re-spin that has been given one of the three features of the free spins.
