Low paying icons are represented by the A to J playing card royals whereas the premiums are denoted by the lynx, eagle, deer, and bison. On top of that, the mountain is the wild, while the scatter is a golden coin.

Keep an eye out for these boosters as you play Unstoppable Bison™ for free or real money:

Respin! Feature

The respin feature is only available in the base game. The feature is activated when four bison land as a stack that covers their reel. Once a respin is triggered, all bison symbols move to the leftmost position in their row and stick while other reels respin. Each new bison that lands in the respin awards another respin, and this continues until no new bison appears or the grid is entirely covered by bison symbols.

Stars Collection Feature

A bison symbol can appear with a star. The star is collected to a meter in the base game. The more the stars the higher the chances of activating the bonus game.

Bonus Game

Collected stars can randomly trigger the bonus game during the base game. A spin of a prize wheel is awarded, which guarantees winning the Mini, Minor, Major or Mega jackpot payouts worth 10x, 40x, 200x or 5,000x your wager respectively.

Free Spins Feature

Landing 3, 4, or 5 gold coin scatters triggers 5, 6, or 7 free spins, respectively.  The only symbols that appear during free spins are the Bison and blanks. Each bison that lands moves to the leftmost blank position in their rows and remains stuck until the free spins feature ends.
