How Release the Bison turns Wilds into respins
Release the Bison uses a 5×4 reel set with 20 fixed paylines, so regular wins form from left to right. Landing four or more Bison Wilds starts the Wild Respin feature, where every Wild moves to a new position after each respin. A newly landed Wild awards another respin and raises the total win multiplier by x1.
A non-winning base spin can randomly change into a guaranteed payout worth 10x-40x the stake. Scatters collected in the base game or during Wild Respins can open the bonus wheel, which sets up to 18 free spins and a starting multiplier of up to x5 before the roaming Wild collection begins.
Roaming Wild and wheel features
- Wild respins: Four or more Bison Wilds roam and can award another respin.
- Rising multiplier: Each new Wild adds one respin and increases wins by x1.
- Guaranteed win: A losing base spin may change into a random 10x-40x payout.
- Bonus wheel: Three or more Scatters award up to 18 spins and a 2x-5x multiplier.
- Roaming sticky Wilds: Bonus Wilds remain visible and move after every free spin.
- Wild collection meter: From the fifth Wild onward, each one adds a spin and x1.
Who may enjoy the roaming-Wild chase
- Roaming Wild fans: You like features where Wild positions change across repeat spins.
- Meter-progress players: You prefer extra spins and multipliers earned through collection.
- Fixed-line players: You want 20 paylines rather than a large ways-to-win grid.
- High-risk players: You accept quiet stretches while waiting for feature-led peaks.
High volatility can make the wait for roaming Wild features costly at larger stakes.

Free-spin wheel, Wild meter and payout profile
Three or more Scatters trigger a wheel that awards up to 18 free spins and a starting multiplier of up to x5. Every Wild that lands in the round becomes sticky for the remaining spins, but it also moves to a new position after each spin. This turns the bonus into a shifting coverage feature rather than a standard locked-Wild round.
Wilds are also counted in a collection meter. From the fifth collected Wild onward, each additional Wild adds one free spin and increases the active multiplier by x1, so later collections can extend and strengthen the same round. Eligible versions may also offer Bonus Bet and Bonus Buy controls, with availability and pricing set by the casino configuration.
