Inside the game
The bonus wheel establishes spins and a starting multiplier, then a persistent Bison Wild moves across the fixed-line grid and builds towards repeatable five-appearance upgrades.
Wins form across a 5×4 reel set on twenty paylines. The provider also describes random guaranteed wins and respins, while three, four or five gems landed in base play can provide a multiplier up to 5x.
The bonus can begin with as many as eighteen Free Spins and a multiplier selected from 2x, 3x, 4x or 5x.
Instead of leaving after one spin, the special Wild moves through the game area and contributes appearances towards a visible collection target.
Completing a Bison set awards more turns and advances the progressive multiplier, allowing later Wild passes to affect a stronger feature.
Five Bison appearances that add turns and raise the feature multiplier
The bonus wheel sets the number of turns and a starting 2x–5x multiplier. Note both results so later Bison upgrades are easy to measure.
The Bison moves through the grid rather than acting as a one-spin substitute. Track its position and every appearance towards the collection threshold.
Reaching the target awards additional spins and increases the progressive multiplier. A nearly complete set only matters if the feature has time to finish it.

Release The Bison is a 5×4, 20-line slot whose bonus wheel can award up to 18 Free Spins and a starting 2x–5x multiplier.

Collecting five Bison appearances awards more spins and raises a progressive multiplier, while base play can include guaranteed wins and respins. Landing three, four or five gems can supply a multiplier up to 5x.
Release The Bison combines a traditional fixed-line base game with a bonus that has visible movement. The 5×4 grid uses twenty paylines. The provider lists random guaranteed wins and respins; landing three, four or five gems within the base game can also supply a multiplier up to 5x, but the Bison feature is the main reason to play. Its wheel awards up to 18 Free Spins and selects a starting multiplier from 2x to 5x. A Bison Wild then travels across the reels rather than disappearing after one result. Five Bison appearances award more spins and increase the progressive feature multiplier, giving each pass a role in a larger collection target. The reviewed playable version lists 96.54% RTP, provider-labelled medium volatility and a 3,000x maximum. The published ceiling limits the possible win from a session; it says nothing about how often the roaming Wild will cross a five-Bison threshold. Players who enjoy roaming Wilds and a bonus with obvious progress should find it easy to follow. Players choosing mainly by maximum-win potential may prefer alternatives with a larger published cap. In the demo, note the wheel's starting terms, then count complete groups of five Bison appearances. A feature can look busy while failing to cross an upgrade threshold, so movement alone is not the useful measure. The best rounds combine a favourable opening multiplier with enough early Bison activity to earn added turns, giving later Wild passes a stronger value. The three supplied stills are ordinary 5×4 base-game screens. The first shows animal symbols, the second one Bison Wild and the third two Bison Wilds on separate reels, but none shows the wheel, a Free Spins counter or an upgrade being awarded. The moving Wild and five-Bison upgrade come from the provider's rules; when testing the demo, wait for an active feature before counting its progress.
