Bison Blocks

Bison Blocks is a six-reel video slot from Stakelogic, released in July 2023, that swaps the usual wide-open American prairie for a darker, more mysterious woodland setting — a deliberate departure from the countless buffalo-themed slots that lean on bright blue skies and rolling grassland. Instead, Stakelogic leans into the murkier, moodier visual language the studio has used in earlier releases, giving Bison Blocks a tone closer to a forest thriller than a nature documentary.

Setting the scene

Rather than chasing herds across open country, players spin through a shadowy, wooded backdrop that feels distinctly different from the typical bison slot formula. It's a theme choice that won't be for everyone — if you're after sun-drenched plains and soaring eagles, this isn't quite that game — but it does give Bison Blocks a visual identity of its own within the genre.

How the reels work

The game runs across 6 reels, and rather than a fixed set of paylines it uses a cascading, ways-to-win structure that can climb up to a maximum of 46,656 ways, giving winning combinations plenty of routes to land as symbols tumble and refresh. Betting is flexible, running from 20p/c up to £/€100 per spin, and there's an optional Super Stake feature that doubles the base bet in exchange for extra scatter symbols appearing on the reels — a trade-off aimed at boosting your chances of triggering the free spins round without changing the underlying symbol values.

RTP and what it means for you

Bison Blocks carries a confirmed RTP of 96.05%, a solid figure that sits above the market average and suggests the game is built to return a fair share of stakes back to players over the long run. For every £100 wagered across a large number of spins, the mathematical model returns £96.05 on average — a number that only reveals itself over thousands of spins, not any single session.

Volatility and hit rate

Stakelogic has rated Bison Blocks as High volatility, a full 5 out of 5 on their own scale. That means the game is built for streaky play: expect stretches with limited action punctuated by the occasional heavier hit, rather than a steady drip of small wins. Pairing that with the tumbling reel mechanic and Super Stake option makes for a slot where bankroll management matters — smaller stakes let you ride out the dry spells and stay in the game long enough to hit a feature.

Max win and buying in

The maximum win on Bison Blocks is capped at 15,000x your stake, a genuinely game-changing ceiling if the free spins round lines up in your favour. For players who don't want to wait for scatters to land naturally, Stakelogic also offers a bonus buy menu with several free spins packages priced between roughly 100x and 250x the bet, depending on how many spins you want to start with.

Final verdict

Bison Blocks trades the expected sunny plains for a darker, denser woodland take on the buffalo slot formula, backed by a competitive 96.05% RTP and true high-volatility swings. If tumbling wins, a huge 46,656-ways ceiling and a genuine 15,000x max win sound appealing, it's well worth loading the free demo at johnessyslots to see how the reels behave before deciding whether to bet real money on it.
