Bison Blocks — a slot by Stakelogic, released in 2023. The game uses a North American prairie, bison and natural landscape theme: colourful bison, card suits, Wild, Scatter and bonus symbols appear on the reels.

The base game grid consists of 6 reels and 4 rows with 4096 ways. After a series of consecutive cascades, the grid can expand up to 6×6, increasing the number of ways to win to 46656. Stakelogic’s official page lists a 96.05% RTP, a 15000x Max Multiplier and high volatility. SlotCatalog also lists bets from 0.20 to 100 and a release date of 23 June 2023.

Bison Blocks belongs to volatile video slots with cascading mechanics and expanding reels. The game is unusual because losing symbols, rather than winning symbols, are removed after a win: if the new symbols add to the combination already formed, the cascade continues.

Expanding Reels are one of the game’s main mechanics. After three consecutive cascades, the grid expands with additional rows, opening more ways to win and increasing the potential of a single round.

Cascading Symbols work in an unusual way. In Bison Blocks, losing symbols are removed after a win while the winning group remains on the grid. If the new symbols improve the combination, the cascade continues.

Progressive Multiplier enhances the bonus mode. During Free Spins, the multiplier can increase with new wins and does not reset immediately after each cascade, making the free spins the main source of high potential.

Free Spins are triggered by Scatter symbols. The bonus round can begin with a different number of free spins, and its value depends on grid expansions, cascades and the progressive multiplier.

Wild symbols substitute for regular symbols and help continue winning combinations. In a game with 4096–46656 ways, Wilds are especially important because they can connect matches across adjacent reels.

Super Stake increases the chance of entering bonus features for a higher stake if the option is available from the operator. Bonus Buy lets you purchase Free Spins directly in versions where the feature is permitted.
