Slot Summary

Players comfortable with high volatility and an x3000.00 ceiling have the clearest reason to consider Release the Bison. Pragmatic Play uses a traveling Bison Wild as the connection between Respins and Free Spins, then lets a Prize Wheel determine the opening spin count and multiplier. Random rewards can also convert an otherwise losing base spin, so the feature set creates several distinct interruptions rather than relying on one trigger alone.

How It Plays

The base game uses 20 paylines, with ordinary combinations occasionally interrupted by a Random reward that can turn a losing result into a guaranteed win.

Respin Wild symbols move between reel positions during Respins. Their movement makes the Bison Wild a continuing event rather than a single substitution on one result.

Theme & Atmosphere

Wildlife and Nature define the frontier setting, with the bison joined by an eagle and coyote among the game's animal imagery.

The Safari and Patriotic tags frame the landscape as an American frontier expedition, while Gems provide the treasure-hunt cue used by the multiplier mechanic.

Nature Gems Animals Safari Patriotic Wildlife

Features & Win Potential

Landing 3, 4 or 5 Gems in the base game applies a random multiplier from x2 to x5, giving the collection of Gems an immediate payout role.

The Walking Wild can trigger Respins as it crosses the reels. Separate Random reward events can also turn a losing base spin into a win.

Bonus & Free Spins

The Prize Wheel awards up to 18 Free Spins and selects a random multiplier from x2 to x5 before the round starts.

During Free Spins, a guaranteed Bison Wild travels across the grid. Collecting 5 awards Additional Free Spins and raises the Free Spins Multiplier for subsequent results.

How this works

Each simulated spin either misses or returns a win drawn from a log-normal distribution, with the hit rate and spread set by the slot's volatility tier (High). The model is calibrated so the average return equals this slot's published RTP (96.54%), with wins capped at its top multiplier (3,000×).

This is a simplified, parametric model of the game's math — not its real paytable. It exists to make the house edge visible over many sessions, so the numbers above are averages across thousands of runs, never a forecast of one.

This is math, not a prediction. Real sessions vary wildly, and no strategy changes a game's built-in house edge. Play for fun, set limits, and never bet more than you can afford to lose.
