Full Rules & Information About the Wild Bison Stampede Online Slot

The setup of Wild Bison Stampede is straightforward. The grid is 5×4 and has 20 paylines on which you can create winning combinations. As usual, they run from left to right.

To win and get paid, you need three to five instances of the same symbol to land adjacent to a payline. These symbols need to start on the far left reel to count as a winning combination.

Regular wilds can appear on reels 1, 3 and 5. Stacked wilds, which are four positions high, can land on reels 2 and 4. Both wilds substitute for all standard paying symbols to help you win.

There are eight regular symbols you’ll see on the reels as you play Wild Bison Stampede. The four low-paying ones are the playing card royals J, Q, K and A. Offering bigger payouts are four themed animal symbols.

The four animals are a raccoon, a wildcat, a wolf and an eagle. The most valuable of these is the eagle, which pays 28x for five on a payline. The regular and stacked wild both have the same top payout.
