Bison Blocks™ Theme
Widely known for their unconquerable spirit, bison are also associated with strength, freedom, abundance, and prosperity. In Bison Blocks™, they thunder across the rocky landscapes and bring sizable wins reaching as much as 15,000x the bet.
The playing grid is set against the backdrop of a rocky canyon enveloped in a thin layer of mist. There are four high-paying symbols depicted as four bison and four playing card suits. The Wild and Scatter symbols follow the bison-inspired theme of the slot.
As players spin the reels of Bison Blocks™, they listen to a piece of American Indian music along with the sound of the cascading blocks, reminiscent of bison thundering across a plain.
How Bison Blocks™ Compares to Other Slot Games
There is no shortage of bison-themed slots developed by other leading iGaming companies.

The top wins players can look forward to are equal to 10,000x the bet.€20 per bet, which is fairly limiting compared to other slot games.

Bison Blocks™ Symbols and Payouts
The winning combinations in Bison Blocks™ start from the leftmost reel and require three to six matching symbols on consecutive reels. Four consecutive cascades will expand the number of rows from four to six. The number of paylines will also rise from 4,096 to 46,656.
The slot’s high-paying symbols are four images of bison against a red, violet, blue, and green background. When players score 6 matches on adjacent reels, these produce payouts of 10x, 5x, 3x, and 1.5x, respectively. Hearts, clubs, spades, and diamonds bring low-value returns ranging from 1x to 0.7x the bet for six-fold combinations.

Bonus Features Overview
Bison Blocks™ offers players a unique cascading wins mechanic, which works by removing the losing symbols from the grid, and not the winning ones. The Free Spins with Multipliers are the central attraction of the slot, which can be purchased through the Buy feature. Furthermore, the slot is linked to the Progressive Jackpot System of Stakelogic. We are now going to review all these attractive bonus features.
Wilds and Scatters
Bison Blocks™ is equipped with a Wild Symbol, depicted as a yellow-orange ‘W’ reminiscent of bison’s fiery nature. The Wild steps in to complete winning combinations with all symbols from the slot, except the Scatters.
Players will easily recognize the Scatter Symbol, as it features bison carved in stone with the ‘Free Spins’ inscription on it. Landing three or more Scatter Symbols anywhere on the grid launches the game’s Free Spins mode.
Free Spins, Multipliers, and Free Spins Retrigger
Depending on the number of Scatter Symbols in view, players can trigger a different number of Free Spins:
- Three Scatter symbols unlock 10 Free Spins
- Four Scatter symbols unlock 12 Free Spins
- Five Scatter Symbols unlock 14 Free Spins
- Six or more Scatter Symbols unlock 16 Free Spins
The Scatter Symbols can land on any of the six reels and explode during cascades. While the Free Spins mode is on, a win Multiplier starting at 1x will be active. It increases by one with each cascade and does not reset. Retriggering the Free Spins is possible, if players manage to land at least three Scatter Symbols. They launch five additional Free Spins.
Buy Feature
Much like other slots produced by Stakelogic, Bison Blocks™ is equipped with a Buy Feature, enabling players to unlock a different number of Free Spins against a predetermined premium. There are five options to pick from:
- 10 Free Spins cost 100x the bet
- 12 Free Spins cost 150x the bet
- 14 Free Spins cost 200x the bet
- 16 Free Spins cost 250x the bet
- A random number of Free Spins (10, 12, 14, or 16) cost 175x the bet
Super Stake Feature
Bison Blocks™ comes equipped with Stakelogic’s proprietary Super Stake feature. It works by doubling players’ current wagers but does not change the payouts of the paytable. It improves their chances of landing more Scatter Symbols, which trigger the game’s exciting Free Spins rounds.
Spin To Win™
Besides its innovative win mechanic and multiple features, Bison Blocks™ is hooked up to Stakelogic’s unique Spin to Win Progressive Jackpot System. It has been specifically developed by the studio to connect the exciting worlds of slots and live casino games. The jackpot feature picks a random slot player, who is redirected to the company’s Live Studio. A live presenter spins the first Mega Money Wheel, which comprises monetary prizes and one Jackpot segment. If the pointer stops at the Jackpot segment, the live presenter will spin the Jackpot Wheel, with sections for Mini, Major, and Grand jackpots.
