Bison Wilds DoubleMax

Bison Wilds DoubleMax is a five-reel, 20-payline slot from Reflex Gaming, a Yggdrasil YG Masters partner studio, built around the DoubleMax multiplier system that has powered some of Yggdrasil's biggest-hitting releases in the past. Released in September 2024, it drops players into American wilderness territory alongside eagles, wolves, cougars and, of course, bison.

Rugged wilderness, Reflex-style presentation

Visually, this is a game that leans into explosive, high-energy effects rather than quiet, scenic nature photography — winning symbols detonate off the reels, grass and sunlight fill the background, and the soundtrack carries a genuinely spirited energy. It won't be to every player's taste if you're after a slow, immersive nature theme, but it delivers a punchy, arcade-like presentation that suits the DoubleMax mechanic's escalating tension well.

How DoubleMax builds momentum

The core loop plays out across a 5x3 grid with 20 fixed paylines, where symbols include card royals worth modest multiples of the stake alongside animal symbols — eagles, wolves, cougars and horses — that pay considerably more for five-of-a-kind. Wilds substitute for any regular symbol to help complete lines. The signature DoubleMax feature doubles a running win multiplier with each consecutive cascade during a winning sequence, so a lucky chain of tumbles can snowball quickly into a much larger payout than the base symbol values suggest. Players can also opt into a Golden Bet, which raises the stake by 25% in exchange for a better chance of triggering free spins.

RTP: a fair-but-not-flashy 94%

Bison Wilds DoubleMax carries a confirmed RTP of 94%, a figure that sits a little below the market average for modern slots. It's not a bad return by any means — over a large number of spins, the game returns £94 for every £100 wagered — but players chasing the very top end of RTP tables should note this one isn't among the most generous.

High volatility built for the multiplier chase

Reflex Gaming has rated the game High volatility, a rating that makes sense given how DoubleMax rewards long cascading sequences. That means dry spells are part of the deal, but so is the potential for a single well-timed sequence to snowball into a genuinely large win once the multiplier starts compounding.

Max win and stakes

The maximum win multiplier is a substantial 19,996x the triggering stake, one of the bigger ceilings covered in this batch, and comfortably within reach of DoubleMax's escalating design. Bets run from 20p/c up to £/€100 per spin, giving room to scale from cautious to committed play.

Final word

With near-20,000x max win potential, genuine high-volatility swings and the proven DoubleMax cascade system behind it, Bison Wilds DoubleMax is built for players chasing bigger, streakier sessions rather than steady grinding. The 94% RTP is a fair trade-off for that ceiling — try the free demo at johnessyslots first to see how the multiplier builds before playing for real money.
