The game is set on the North American plains and plays on a 4x5x5x5x5x4 layout with 10,000 ways to win. Three matching symbols on adjacent reels pay from left to right, whatever their position.
How the PowerGrids work
The two PowerGrids sit on reels 2 and 3 and reels 4 and 5. Each one switches on when a coin symbol lands anywhere inside it.
- An active PowerGrid locks for three spins, and the counter resets whenever another coin lands.
- If a PowerGrid fills completely, the values of all its coins are added together and paid on top of any standard wins.
- Prize Reel symbols landing inside a PowerGrid trigger an Ultra Prize Reel spin. It can award a multiplier for all locked coins, one of the MINI, MINOR, MAJOR or GRAND prizes, or a COLLECT icon that pays instantly and ends the feature.
Free Spins and Buy Bonus
Three or more buffalo scatters award 6, 8, 10 or 12 Free Spins, depending on how many land. During the round, coin values are paid at the end, and any PowerGrid that fills pays its prize and resets so it can fill again. More scatters add extra spins.
A Buy Bonus option gives direct entry to Free Spins for 20x the selected bet.
