Bison Rising Megaways

Bison Rising Megaways Slot Review — Blueprint Gaming

Bison Rising Megaways runs on a 6-reel Megaways grid with up to 117,649 ways to win per spin, built around an Avalanche mechanic that lets winning symbols cascade away and new ones drop in without a fresh bet. Blueprint Gaming, the Newark, England-based studio behind Buffalo Rising Megaways All Action and Gorilla Gold Megaways, released this title on 19 October 2018. The combination of a variable reel count and a Bonus Buy option sets it apart from slots built around a single fixed line structure.

Core Gameplay Experience

The Megaways engine recalculates the symbol count on each reel per spin, allowing the ways to win to reach up to 117,649 rather than remaining tied to a fixed payline count. Each cascade from the Avalanche mechanic can then shift that ways total again before the spin ends, so a single bet can pay out through several consecutive tumbles rather than one static result.

The visual theme draws on North American wildlife, pairing bison, wolves and bear imagery with diamond-style high-value symbols, set against a pale blue backdrop and rendered mostly in warm brown tones. It sits within the Animals & Nature themed slots grouping, alongside other wildlife-themed titles from the same studio.

Features and Mechanics

Megaways governs the base mechanic: reel heights vary each spin, producing up to 117,649 ways to win, and several more mechanics layer on top of that grid. Wild symbols substitute for standard paying symbols to complete combinations, Stacked Symbols let matching icons fill multiple positions on a single reel at once, and a Mystery Symbol lands across several positions before revealing as one uniform symbol once the reels settle, turning a mixed set of icons into a single matching type.

Scatter Symbols trigger the Free Spins round, which opens with a Free Spins Selection screen: the player picks one of several available configurations before the round begins. Wins collected during that round are boosted by a Free Spins Multiplier, and the same Avalanche and Cascades tumbling mechanic that runs in the base game continues to apply, so a single Free Spins drop can still chain into consecutive wins. A Bonus Buy feature lets a player pay directly for entry into the Free Spins round instead of landing scatters naturally.

The RTP Range feature reflects something less common: Blueprint Gaming publishes more than one payout build for this title, a detail covered in the next section along with what each build means for the player.

RTP, Volatility and Payout Model

Bison Rising Megaways pays out at a theoretical RTP of 96.5% on its main build, with medium volatility as its risk profile. Blueprint Gaming’s own game information also lists lower builds at 92.02% and 93%; which version runs at a given casino is set by the operator and shown in that casino’s own game information panel, not chosen by the player in advance.

Medium volatility means win frequency and win size sit between the extremes: neither the long scoreless stretches of a high-volatility design nor the small, frequent returns of a low-volatility one. On a bankroll basis, a player can expect a steadier run of smaller wins punctuated by occasional larger ones, rather than needing the deep reserve that a high-volatility Megaways title would call for, a reading consistent with how volatility is scored in our review methodology.

Blueprint Gaming’s own game page also lists a Bison Bet mode with a separate minimum stake of 10 — a hundred times the main game’s minimum of 0.1 — and its own RTP of 97.01%.

Similar Slots — Comparison

Among the six Blueprint Gaming titles shown in the comparison above, maximum wins range from 2,500x on Bison Rising Gold Strike to 50,000x on both Big Cat King Megaways and Return of Kong Megaways, while Buffalo Rising Megaways All Action matches this slot’s own 10,000x ceiling. The RTP gaps are mostly small: Bison Rising Megaways returns about $0.50 more per $100 of bets than Bison Rising Gold Strike and roughly $0.47 more than Return of Kong Megaways, in theory, while it gives back close to $0.50 less than Gorilla Gold Megaways and about $0.51 less than Buffalo Rising Megaways All Action; against Big Cat King Megaways the two sit at the same 96.5% level, with no theoretical difference between them. The clearest split is mechanic rather than math: Bison Rising Gold Strike replaces Megaways and Bonus Buy with ways-to-win math built around Hold & Win and a jackpot, so a player drawn to that respin-and-jackpot format should weigh the mechanic difference rather than the RTP numbers alone.

How to Play Bison Rising Megaways Online

A demo version of Bison Rising Megaways is available, making it possible to test how the Megaways grid and the Avalanche tumble interact before any real-money wager, independent of which RTP build a given casino later runs.

Blueprint Gaming titles, including this one, are carried by 50 casinos as of 27 October 2026; the full list sits on the Blueprint Gaming hub, alongside the studio’s other Megaways releases.

Opening the game from the Slots category and checking the RTP shown in a casino’s own game information before setting a stake is a reasonable first step.

Verdict on Bison Rising Megaways

Bison Rising Megaways pairs a 6-reel Megaways grid with Avalanche tumbles, a Free Spins round built around a selection screen and multiplier, and a Bonus Buy shortcut into that round, all running at a theoretical 96.5% RTP and medium volatility with a 10,000x ceiling. That profile suits a player who wants Megaways variability and tumble-based extra wins without committing to the higher-volatility end of Blueprint Gaming’s catalogue, such as Gorilla Gold Megaways or Buffalo Rising Megaways All Action. It is less suited to a player chasing the largest prizes in this comparison set, since Big Cat King Megaways and Return of Kong Megaways both carry a higher 50,000x ceiling, and it is not the right pick for a player who wants a jackpot-and-respin format, which is what Bison Rising Gold Strike offers instead under the same series name.
