Inside the game

How it plays

The 4 highest paying symbols can double: when a reel ends up entirely filled with a single kind of symbol, those symbols count as two symbols each in the win for that spin. This means a win can reach up to 10 symbols on any betline. Free Spins get activated once the main game shows at least three Scatter symbols. Stacked Wilds are added to the reels during Free Spins.

NetEnt publishes an RTP of 96.10%, a 16% hit frequency and a maximum payout of 1,700 times the bet. The grid is 5×3 with up to 10 paylines, and bets run from €0.10 to €200.00. On NetEnt’s scale the volatility index is 7.6.
