Release the Bison

Release the Bison is a 5-reel, 20-payline slot from Pragmatic Play set in the American frontier. The game features symbols of the wild west including buffalos, along with standard 10-A royals as the lower pays. Buffalo wilds substitute for regular pays and are central to the slot's bonus features.

In the base game, landing 4 or more wild symbols triggers the Wild Respins feature. During this bonus, all wilds roam to random positions on each respin, with the multiplier increasing by 1x for each new wild that lands. Any scatters collected during the respins can trigger the Free Spins round if at least 3 are collected.

Release the Bison also has a Guaranteed Win feature where any non-winning spin can randomly award a prize of 10-40x the stake. The Free Spins bonus is triggered by landing 3, 4 or 5 scatters, awarding up to 18 free spins with a starting multiplier of 2-5x. During free spins, wilds that land remain sticky for the duration of the feature and also increase the multiplier when 5 or more are collected.

The slot has high volatility and a maximum win capped at 3,000x the stake. The default RTP is 96.54% but can be lower depending on operator settings. The bonus buy allows direct access to the free spins for a cost of 80-300x the stake.
