Bison Rising Megaways plays on a six-reel grid where the number of symbols per reel changes on every spin. Winning combinations form when matching symbols land on adjacent reels from left to right. The game features various North American animals as high-paying symbols alongside standard card icons. Cascading reels remove winning symbols to allow new ones to drop into the empty spaces.

Landing four scatter symbols triggers the free spins bonus where an unlimited win multiplier increases with every cascade. This game suits players who prefer high volatility mechanics and the potential for large payouts during the bonus phase.
