Bisonous Fever (Foxium) – Slot Review
Bisonous Fever by Foxium carries a strong Wild West theme, blending classic cowboy imagery with modern slot-machine aesthetics. The visuals revolve around dusty frontier settings, saloons and gold-rush style symbols, creating a lively atmosphere inspired by old-school Western gambling culture. Although detailed official descriptions are limited, the game’s design clearly leans into a mix of rodeo energy and vintage Vegas flair, combining cowboys, revolvers, boots and hats with glowing coins and jackpot mechanics.
The theme feels less like a serious historical Western and more like a stylised casino fantasy set in the frontier era. Bright colours, spinning reels and collectible cash symbols give it an arcade-like vibe, while the western props reinforce the idea of chasing riches during a gold-rush adventure. Overall, Bisonous Fever presents a playful take on cowboy culture — more focused on fast action and prize collecting than storytelling — delivering a modern slot wrapped in a familiar saloon-style setting.
Bisonous Fever features a 5-reel, 4-row layout with 40 fixed pay lines. The game offers medium volatility, an RTP of 96.4%, and a maximum win potential of up to 10,000x the stake, with bet sizes ranging from £0.20 to £25.
Bisonous Fever Symbols & Pay Table
The pay table includes 14 symbols. Low-value icons are represented by J, Q, K and A, while premium symbols feature classic Western-style items such as Horseshoes, Bells, Cowboy Boots, Revolvers and Cowboy Hats. Special symbols include the X Symbol, Cash Symbol, Collect Symbol, Wild Symbol and Jackpot Tokens. The Wild is the highest-paying symbol, awarding up to 25x for five of a kind and substituting for all regular symbols except Cash, X and Collect symbols. Collect symbols may appear on reel five during the base game.
Bisonous Fever Features & Mechanics
The Collect Feature is activated when a Collect symbol lands on reel five, awarding the combined value of all Cash symbols currently visible. A Collect Multiplier meter starts at 1x and increases by 0.5x whenever an X symbol appears on reel one, up to a maximum of 5x. When a successful collect occurs, the multiplier resets to 1x, though it remains unchanged if no Cash symbols are present.
Cash Symbols can land on reels one to four in the base game and on any reel during bonus rounds, awarding values between 0.5x and 50x the bet. Jackpot Tokens may also appear, gradually increasing the value of Mini, Minor, Maxi, Major, Mega and Grand jackpots, which can only be won during bonus games.
Three different Bonus Games can be triggered, each beginning with three spins on a 5×4 grid that can expand up to 5×8 by unlocking additional rows through collected Cash symbols. Every time a new Cash symbol lands, the spin counter resets. The feature ends once spins are exhausted or the grid is completely filled.
Each bonus type introduces unique mechanics. The Vortex Collect bonus focuses on accumulating purple Cash symbols, with vortex collects gathering values from the grid. The Multi Quake bonus centres on red Cash symbols, where fire boulders apply multipliers to increase coin values. The Thunderbolt Upgrade bonus uses blue Cash symbols and randomly boosts selected coin values. Special symbols such as Jackpot Maximiser and Mystery icons can appear across all bonus modes, adding further upgrades and potential payouts.
Conclusion
Bisonous Fever by Foxium delivers a solid mix of Wild West visuals and coin-collect mechanics, offering steady action through its cash symbols, collect features and expanding bonus rounds. The game’s medium volatility and progressive grid unlocks create moments of excitement, especially when multiple modifiers land together, making it appealing for players who enjoy structured bonus gameplay.
However, the experience isn’t without drawbacks. The base game can feel repetitive and heavily reliant on collect symbols to generate meaningful wins, which may leave long stretches with limited engagement. Some features also feel overly familiar, borrowing heavily from existing coin-collect formats rather than introducing something truly unique.
