Bison Blocks is a 6 reel, 4 row video slot game developed by Stakelogic. Six rows will appear after three successive cascades have taken place. Because the number of rows is variable, the initial 4096 winning permutations can grow to a maximum of 46656 permutations. The minimum wager you can place is 0.20, and the maximum is 100. The game's return to player percentage (RTP) of 96.05% is just below the industry standard. Bison Blocks is a high-volatility game with a maximum win of 15000 times the initial wager.
Three or more identical symbols anywhere on adjacent reels (left to right) trigger a payout. The winning symbols will remain on the reels, while the losing one's will be cleared away.
Diamonds, spades, clubs, and hearts are the low-paying suits. Six of a kind of winning symbols pay off anywhere from 0.70 times to 1 times the wager. Bison in green, blue, purple, and red are the highest-paying icons. Six of a kind of winning symbols will award a payout of 1.5X to 10X the wager. The golden W represents the wild symbol, while the bison statue engraved with "Free Spins" acts as the scatter.
The cascade function is triggered whenever a winning combination is formed. After then, only the winning symbols will stay on the reels, while the losing ones are taken off. If the prize is multiplied by landing another symbol of the same kind, the cascade feature will keep going. This will keep happening as long as the cascade is used to extend a win or establish a new one.
The free spins feature is triggered by landing three or more scatter symbols during cascades. When 3, 4, 5, or 6 scatters appear, the player is awarded 10, 12, 14, or 16 bonus spins. Landing scatter symbols will explode and be added to a metre so that more symbols can land during cascades. Five more free spins are awarded if 3 or more scatter symbols appear during the bonus round.
The initial win multiplier is 1X, and it will grow by 1X with each successive cascade. All subsequent victories are multiplied by this win multiplier. If you manage to string together three consecutive wins, the reels will expand to a 6X6 configuration, giving you 46656 opportunities to win on one particular spin.
