  1. Set your stake. Choose your total bet per spin. Wins are paid as multiples of this stake.

3 features explained: wild symbols, expanding wilds, respins

Wild symbols

Wilds substitute for regular paying symbols to help complete winning combinations. They do not normally replace scatter or bonus symbols.

Expanding wilds

When an expanding wild lands, it grows to cover its whole reel, turning one symbol into a full column of wilds.

Respins

Selected reels or the whole grid spin again without a new stake, usually triggered by a specific symbol combination or near-miss feature.

Strategy tips (members only)

  • Bonus wagering: at 96.3% RTP, clearing $1,000 of wagering costs about $37.00 on average. Check the bonus terms, as some casinos exclude specific games. Run your numbers in the wagering calculator.
