Big Bad Bison Slot Review – Free Play by Big Time Gaming

Big Bad Bison Slot Facts

The Big Bad Bison slot from Big Time Gaming pays out up to 67,640 times the stake at a 96.59% RTP, spread across a six-reel Megaways grid with as many as 117,649 winning ways on a single spin. Set against a North American canyon backdrop, this one leans on wild multipliers and a free spins round that keeps raising its own floor. Medium volatility keeps things approachable, with the option to trade a strong base-game win directly for a chance at more spins.

Big Bad Bison Theme & Design

Big Time Gaming places the reels against a canyon at sunset, built around the wildlife that roams the American frontier. The bison of the title anchors the symbol set, alongside other creatures native to that same rugged landscape, giving the game a grounded outdoors feel rather than anything fantastical. Wild symbols carry hidden multiplier values, which fits the sense of a wilderness where the biggest rewards are hiding in plain sight rather than announced upfront. The overall mood favors a quiet, scenic wilderness rather than fast-paced action, even without further detail on the soundtrack or animation style.

How Big Bad Bison Plays

Every spin reshuffles the Megaways grid, so the number of ways in play shifts from one spin to the next, climbing as high as 117,649 at its widest. Wild symbols are the base game’s main draw, each one hiding its own multiplier worth as much as 5x, so a wild landing inside a winning combination can inflate that payout well beyond what the symbols alone would pay. Landing three or more scatters opens the free spins round, and this is where the game’s structure really shows: two or more scatters appearing during a spin retrigger the round for four extra spins plus two more per additional scatter, and each retrigger also raises the minimum number of ways available through whatever remains of the bonus. String together enough retriggers and the grid settles at the full 117,649 ways for every remaining spin. On top of that, building a win somewhere between 25 and 50 times the stake opens the choice to gamble the whole amount away for a chance at more free spins, while a win of 50 times the stake or beyond skips the gamble entirely for a guaranteed batch of spins instead.

RTP, Volatility & Win Potential

A 96.59% RTP sits just above the industry average of around 96%, paired with Medium volatility and a hit frequency of 37.3%, meaning winning spins land more than a third of the time. That combination points to a game that pays back reasonably often without needing an extreme swing to feel rewarding, though the true ceiling is a maximum payout of 67,640 times the stake, reached only when the free spins round runs long with several retriggers stacking the minimum ways higher and higher.

Our Verdict on Big Bad Bison

This Big Bad Bison slot review comes down to a pick for players who like Megaways mechanics but want Medium volatility rather than the harsher swings some BTG titles bring, plus the added wrinkle of choosing whether to bank a win or gamble it for more spins. The strength is how the retrigger system keeps raising its own floor, so a long free spins round can feel like it is constantly leveling up. The catch is that reaching the biggest multiples of the maximum payout still depends on the free spins round running unusually long. A bonus buy and free demo are both available on this page for anyone who wants to see the Megaways grid at full width straight away.

Big Bad Bison Bonus Features & How They Work

Wild Multipliers

Wild symbols on the reels can hide a multiplier worth up to 5x, and because the Megaways grid can offer as many as 117,649 winning ways, a multiplied wild landing inside a winning line can turn an ordinary spin into a considerably bigger payout.

Free Spins

Three or more scatters trigger the free spins round beneath a night sky. During the bonus, two or more scatters landing on a spin retrigger it for four extra spins, plus two more for every additional scatter beyond that. Each retrigger also raises the minimum number of ways available, so the grid keeps opening up the longer the round runs, and reaching five or more retriggers guarantees the full 117,649 ways through whatever remains of the bonus.

Win Exchange™

Building a win worth between 25 and 50 times the stake opens a choice: gamble that whole amount for a chance at 12 free spins, with the odds displayed plainly on a wheel before you decide. Push a win to 50 times the stake or beyond, and the gamble becomes unnecessary, since exchanging exactly that 50x amount locks in the 12 free spins automatically.

Bonus Buy

Players who’d rather skip ahead can buy straight into the bonus for 50 times the stake, unlocking 12 free spins immediately without waiting on scatters to land naturally.
