Bison Blocks is a 6-reel video slot by Stakelogic, released on July 31, 2023. This high-volatility game combines stunning visuals with innovative cascade mechanics, offering players a truly unique gaming experience. With a maximum win of 15,000x your stake and an RTP of 96.05%, Bison Blocks is designed for players who crave big wins and aren’t afraid of the volatility that comes with pursuing them.
Base Game & Features
Bison Blocks features a 6×4 grid of cascading reels that expands to 6×6 after three consecutive cascades, increasing the ways to win from 4,096 to a massive 46,656. The game’s unique reverse cascade mechanic sets it apart from traditional cascading slots: winning symbols remain on the reels whilst losing symbols disappear, and new symbols drop from above to fill the gaps.
Each cascade increases a multiplier by 1x, which is particularly powerful during the free spins bonus round. The game’s dark, moss-filled forest setting features beautifully rendered bison heads carved into stone, creating an atmosphere that feels both premium and immersive. Stakelogic’s commitment to quality over quantity is evident in every pixel.

Betting and Paylines
Your bet range spans from 0.20 to 100 per spin, making Bison Blocks accessible to various player budgets. However, given the game’s high volatility, we’d recommend sizing your bets to your bankroll accordingly. The expanding ways-to-win system means that larger cascades unlock exponentially more winning combinations, rewarding players who hit the right symbol sequences.
Wild and Scatter Symbols
The Wild symbol substitutes for all symbols except the Scatter, which is your gateway to the free spins bonus. The Super Stake feature doubles your bet to increase the frequency of scatter symbols landing, giving you a better chance of triggering the bonus round. This optional feature is worth considering if you’re determined to hit the free spins and don’t mind the increased volatility.
Bonus Features & Free Spins
The free spins bonus is where Bison Blocks truly shines. Land 3, 4, 5, or 6 scatter symbols to trigger 10, 12, 14, or 16 free spins respectively. During the bonus round, every cascade increases a multiplier by 1x. When you land additional scatters during free spins, you’ll gain a further 5 spins, and your multiplier resets but the potential for massive wins accumulates as you rack up more cascades.

Bonus Buy Feature
If patience isn’t your virtue, the bonus buy feature lets you purchase direct entry into the free spins bonus. You’ll choose from four tiers: 100x, 150x, 200x, or 250x your stake. This grants you a corresponding number of free spins (10, 12, 14, or 16), but it’s a premium feature and can eat into your bankroll quickly. Whether the bonus buy represents good value depends on your luck during the free spins round—if you hit that expanding grid and string together multiple cascades with the multiplier climbing, you’ll absolutely feel the cost was justified.

Our Honest Verdict
Bison Blocks is a polished, innovative slot that represents Stakelogic’s commitment to quality game design. The reverse cascade mechanic is genuinely unique, the progressive multiplier during free spins creates legitimate opportunities for 15,000x wins, and the visual presentation is among the best in the industry.

If you’re a casual player or prefer frequent small wins, Bison Blocks will likely frustrate you.
For high-roller players and cascade mechanic fans, however, Bison Blocks is a premium addition to any online casino’s library. It’s complex enough to feel rewarding when you hit a big win, yet straightforward enough that new players can understand the mechanics quickly.
