Three things to watch
- Read both wheel awards before the feature
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.
- Follow the Wild across every reel
The Bison moves through the grid rather than acting as a one-spin substitute. Track its position and every appearance towards the collection threshold.
- Count sets of five Bison appearances
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.
Our take
A travelling Wild gives the bonus a clear route and a reachable upgrade target
Release The Bison combines a traditional fixed-line base game with a bonus that has visible movement. The 5×4 grid uses twenty paylines. Random base-game events can provide guaranteed wins, respins or three to five gem symbols, 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 version lists 96.54% RTP, very high volatility and a 3,000x maximum. The RTP is competitive within this batch, while the ceiling is more restrained than several neighbouring releases. 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.
How it plays
What happens when you spin
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.
The base game uses twenty paylines
Wins form across a 5×4 reel set, with occasional random enhancements able to guarantee results, repeat spins or introduce several gem symbols.
A wheel sets two opening conditions
The bonus can begin with as many as eighteen Free Spins and a multiplier selected from 2x, 3x, 4x or 5x.
The Bison Wild travels across the reels
Instead of leaving after one spin, the special Wild moves through the game area and contributes appearances towards a visible collection target.
Five appearances upgrade the round
Completing a Bison set awards more turns and advances the progressive multiplier, allowing later Wild passes to affect a stronger feature.
One Wild keeps moving
Five Bison appearances extend the chase and lift the multiplier
The wheel determines the opening opportunity, but Bison timing determines whether it grows. Early appearances are valuable because the added turns create space for another complete set.
