Bison Rising Megaways: A Stampede Across the Megaways Plains
The headline numbers are a 96.5% RTP (96.5% with the Bison Bet) and up to 117,649 ways to win.
How the Megaways Reels Work
Each of the six main reels can show between two and seven symbols on any given spin, with a four-symbol horizontal reel feeding the row above. The number of matching ways shifts constantly as a result, climbing toward the full 117,649 when the reels run tall. One spin shows a narrow grid; the next blows wide open.
Symbol values follow the plains theme. Bison and other wildlife act as the premiums, while lower-value symbols use stylised card ranks. As a high-volatility title, the premiums land in long, paying combinations less often than they would in a steadier game, so individual hits tend to be larger when they do arrive.
A cascade mechanic underpins every win. Winning symbols are removed and new ones drop into the gaps, which can chain several wins out of a single spin. The longer the chain runs, the more it matters, and cascades become especially important once the free spins multiplier starts climbing.
Mystery Symbols and Wilds
Wild symbols substitute for all paying symbols across both the base game and the bonus round. The signature extra is the Mystery symbol: when it lands it reveals a single, randomly chosen matching symbol across all of its positions at once. A screen seeded with Mystery symbols can resolve into a large matching cluster in one reveal, turning an ordinary-looking spin into a significant win.
Choose Your Free Spins Mode
Landing four or more scatters on the main reels triggers the free spins round, and before it begins you pick how to play it:
- 15 free spins starting at a 1x multiplier
- 10 free spins starting at a 5x multiplier
- 5 free spins starting at a 10x multiplier
- Mystery choice — a random selection from the three options above
Whichever mode you choose, the win multiplier rises by +1 with every cascade and does not reset between spins. The trade-off is built into the choice itself — more spins at a lower multiplier, or fewer spins that start hot.
RTP, Volatility and Max Win
The base RTP is 96.5%, just above the typical online-slot average. Where a casino offers the Bison Bet, which buys a guaranteed route into the free spins for an increased stake, the return rises to 97.01%. The volatility sits firmly at the high end of Blueprint's Megaways range.
High volatility means the gap between dry spells and big hits is wide; long stretches without a meaningful return are normal rather than a fault. It is a demanding ceiling, but the stacking multiplier gives it a real path.
Playing on Mobile
The grid scales cleanly to smaller screens and the spin, bet and paytable controls are sized for touch. Every feature — cascades, Mystery symbols, the free spins choice and the Bison Bet — is present on mobile, and the 96.5% RTP and high volatility are identical regardless of the device you play on.
