Page updated July 2026
Slotmill is heading back out onto the American prairie with the Wild Bison Stampede slot, related in spirit — though not mechanically — to the studio's earlier title Raging Riches. Coming soon on 20 July 2026, it trades gunslinging outlaws for cactus country, dust and galloping wildlife, wrapped in a honky-tonk soundtrack designed to inject some frontier energy into every spin.
Announced mechanics place the action on a 5x4 grid with 20 paylines, leaning heavily on wild symbol activity to drive the gameplay rather than complex collector mechanics. A Burst mode is set to be included, letting players speed through a set number of spins without the full graphical presentation slowing things down — handy for those who prefer efficiency over spectacle. On the paytable side, Wild West-style J-A royals are expected to sit at the lower end, paying 3x to 5x the bet for a five-of-a-kind win, while raccoons, cats, wolves and eagles occupy the premium tier, worth 10x to 28x for the same combination.
Pre-launch figures put the preferred RTP variant at 96.01%, volatility as medium-to-high, and the maximum win at 6,688x the stake — a more restrained ceiling than some rivals, hinting at a game built for steadier action rather than rare colossal payouts. Stakes are expected to range from 0.20 up to 60 per spin.
Wild Bison Stampede hasn't been released yet, so treat these as pre-release figures until Slotmill confirms the finished game. Johnessyslots.com will have the full review and demo ready the moment it launches in July 2026 — or spend some time with Slotmill's earlier Western release, Raging Riches, while you wait.
