Release the Bison is a popular online slot developed by Pragmatic Play.
Hit 3, 4 or 5 Bonus symbols to trigger the Free Spins feature.
Randomly, when only 2 Bonus symbols hit in the base game, a respin is triggered of the reels that do not contain Bonus symbols.
If a third Bonus symbol appears after respin, the Free Spins feature is triggered.
Before the round starts, a wheel with 2 sides appears.
One side contains the number of free spins and the other, a multiplier.
The wheel spins and a combination of number of free spins and a multiplier is randomly selected.
The chosen combination will determine how many free spins are awarded and a multiplier that applies to all wins during the subsequent round.
