Inside the game

How it plays

In the Expanding Reels Feature, the gaming grid can expand when symbol matches occur around its edges or when bombs explode. When every row of the gaming grid is unlocked, 6 Free Spins are triggered. After the bet way wins pay out, bombs explode before an Avalanche. Persistent Bombs may appear only in Free Spins. Prizes that land on the gaming grid stay there until Free Spins end, and when a bomb explosion covers the position of a prize, its value is multiplied by up to 2,048x.

NetEnt publishes an RTP of 96.07%, a 29% hit frequency and a maximum payout of 4,300 times the bet. The grid is 4×4, and bets run from €0.25 to €100.00. On NetEnt’s scale the volatility index is 7.7.
