Release the Bison - Slot Overview
I came to Release the Bison for its crisp outdoor look and stayed for the classic 5x4, 20 line build. Pragmatic Play sets the scene with mountains and meadows, then lets the features take over. The base game can feel steady, yet the set of tools is clear. You get Wild Respins, random Guaranteed Wins, a Free Spins wheel, plus Ante Bet and Buy Feature options. Stakes start at 20p/€0.20 and scale high. Volatility is on the sharp end, which suits me when I'm chasing bonus driven wins.

Release the Bison - Slot Symbols & Paytable
On the reels, lows are 10, J, Q, K, A. Highs are Bobcat, Hyena, Eagle, and the Wolf, which pays from two of a kind. Five royals pay between 0.5x and 1.5x your bet. Five of a kind high pays range from 2x to 10x, with the Wolf on top. Lines pay left to right, three to five matches, or two for certain top symbols. Wild Bison substitute across the board and form their own wins.
A full line of Wilds pays 12.5x, with smaller sets worth 0.5x, 2.5x, and 5x. Scatters appear as diamonds and trigger bonus play rather than line wins. The paytable is dynamic, so values scale with stake, which keeps things readable when I step bets up or down. It's a straight 20 line model, so placement matters. I found those diagonal routes handy in the mid pay tiers, especially when roaming wilds start to move in bonus modes.

Release the Bison RTP, Volatility, & Max Win
Release the Bison posts a default RTP of 96.54%, with other configurations at 95.48% and 97.49%, and some sites offer 94.49%. Hit rate sits around 28.90%. Volatility is high, and the max win is capped at 3,000x the bet. Stakes cover most pockets, from 20p/€0.20 up to £/€240 in standard play, with some builds showing £/€300 when Ante Bet is active. Ante raises the wager by 25% and increases the chance of triggering free spins, which can tilt the session rhythm.
Release the Bison Special Features
The Wild Respin feature triggers when at least four Wilds land in the base game. All Wilds become roamers that shift to random positions between respins, and wins are evaluated after each move. New Wilds add another respin and push the global win multiplier up by one. Scatters that drop during this mode are collected, up to five. If three or more have been collected by the time respins finish, the game moves straight into free spins.
Guaranteed Win can flip a dead spin into a payout worth 10x to 40x the bet. It fires at random in the base game and breaks dry spells in style. I also like the Ante Bet option. It adds 25% to the current stake and increases the chance of triggering free spins. I keep it off when testing and bring it in once the balance is settled, as it changes pacing and gives those wheel entries more often.
Release the Bison Bonus Rounds & Free Spins
Free spins trigger from three or more Scatters, either in the base game or during Wild Respins. When only two land in the base game, the reels without Scatters can respin for a second look. Before the round starts, a two sided wheel awards a starting multiplier and a number of spins. With three Scatters you can land 8 to 18 spins with x1 to x5. Four Scatters give the same spin counts with x2 to x5. Five Scatters offer 10 to 18 spins with x3 to x5.
During free spins, every Wild that lands turns into a roaming wild that sticks around until the end of the feature. It moves to a different random position between spins and works across lines. All new Wilds feed a collection meter. From the fifth collected wild onward, each extra one grants plus one free spin and raises the global multiplier by one. There is a cap of ten collected wilds, so the second half of a good bonus can build fast.
If patience is thin, the Buy Feature lets you jump straight into bonus at 80x, 150x, or 300x for three, four, or five Scatters. The stated RTPs for those buys sit around 96.55%, 96.57%, and 96.51%. I rate the four Scatter buy as the sweet spot for balance, though the three Scatter option still does a job when I am cycling stakes. The five Scatter buy is pricey, yet the higher starting multiplier can set the tone early.
How to Play Release the Bison Slot
Getting started is simple. Pick a stake within the 20p/€0.20 to high limit range, and spin on 20 fixed paylines. Wins pay left to right, from reel one, with three to five matches on most symbols and two or more on top picture icons. Tap the info panel to view the paytable, lines, and feature rules. Try the demo first, then decide whether to run Ante Bet or use the Buy Feature. I stick to session limits and let the features carry the heavy lifting.
