54%, high volatility and a stated maximum win of 3,000x. The recorded release date is April 29, 2024. Treat the RTP as an average measured over very long play, not as a session forecast.
The volatility rating shows how bumpy the win distribution tends to be, and the max win marks the ceiling of the maths model.

A practical way to test the demo is to keep the stake steady for fifty spins, then repeat at a different level. Check the info screen before you start and after any change to a setting. So the active paylines and bet size are never a guess.
Longer sessions make it clearer how often Release the Bison pays in the base game compared with its feature rounds.
Operators sometimes run different configurations of the same title. So check the RTP, limits and available features inside the casino version you open. What happens in a demo has no bearing on later real-money sessions. Set a spending limit before you start and stop when it is reached.
Landing 3+ Scatters triggers the Free Spins wheel, awarding up to 18 spins and 5x multipliers. During Free Spins, Wilds are collected: 5 Wilds adds more spins and increases the roaming wild multiplier. The Bison Wild Respin feature triggers when 3+ Wilds land, moving across the reels while others respin.
The Guaranteed Win feature can randomly trigger on non-winning spins to award up to 40x. Max win is capped at 3,000x.
How to play the Release the Bison demo: open the game, wait for the interface to finish loading and review the paytable or help menu before starting. Choose a comfortable virtual stake with the on-screen controls, then begin a round and let the result complete before changing settings. The demo uses play credits.
But the controls and feature sequence are designed to mirror the corresponding game experience.
For this slot format, set the virtual stake and press spin. Winning combinations are evaluated according to the paytable after the reels or grid settle. Check whether the game uses paylines, ways, clusters or another win system. That is because this determines how matching symbols connect. Wilds, scatters and bonus symbols may follow separate rules.
The mechanics recorded for this title are Bonus Buy. A Bonus Buy label means direct feature access may be offered in eligible versions. Compare its virtual cost with the normal trigger route. Feature labels summarise the catalogue entry. But the game screen determines the exact trigger, duration and payout calculation.
54% RTP, high volatility and a maximum win of 3,000x. RTP is calculated across a very large number of rounds and cannot forecast a short demo session. Volatility describes the intended risk pattern: higher settings generally mean outcomes may be less frequent and more uneven.
A maximum win is a ceiling and should never be treated as a likely target.
During testing, watch the stake shown before every round, the balance change after settlement, the symbols or events that trigger features and any multiplier that remains active. Try the base game first instead of immediately selecting an optional shortcut.
If autoplay is available, set a limited number of rounds and stop conditions so the session remains easy to follow.
Availability, RTP and feature settings may differ between operators or countries. Always use the paytable and help menu in the exact version being played. Real-money gambling involves financial risk. Use fixed limits, take breaks and never increase a stake to recover a loss.
