Winning Mechanics
- ANY ADJACENT PAYS™ enables winning combinations from matched symbols on any adjacent reels, not limited to starting from the leftmost reel.
- Only the highest win per way is paid.
- Way wins and any credit awards are multiplied by the bet multiplier for the current spin.
- Your bet multiplier is calculated by dividing your total bet by 0.15. For example, a £0.30 stake equals a multiplier of 2 (0.30 ÷ 0.15).
- Payout tables display the number of credits won for each combination at your chosen bet level.
- If there are no winning combinations, the game round ends.
- Any malfunction voids all play and pays.
