Bisonous Fever Slot Guide

Bisonous Fever is a Wild West-themed slot developed by Foxium and published under the Games Global catalogue. The game runs on a 5-reel, 4-row grid with 40 fixed paylines, set in a dusty canyon environment. Bet levels start at 20p per spin.

The game's bonus structure centres on three separate hold and win respin rounds, each triggered by a different dynamite pile collecting a cash symbol. Each bonus uses the same starting respin framework but introduces a distinct modifier - Vortex Collect, Multi Quake, or Thunderbolt Upgrade - during the feature. The grid can expand from 5x4 up to a maximum of 5x8 as cash symbols are collected during the bonus, and six progressive jackpot tiers are available across both the base game and the bonus rounds. The maximum win is 10,000x the stake.

Volatility and RTP

The RTP of Bisonous Fever is 96.4%, sitting above the 96% benchmark common across many comparable slots. The volatility is medium, meaning the game is structured to distribute wins more evenly across base game payline wins, cash collects, and the hold and win bonus features than a high volatility equivalent. The maximum win is 10,000x the total stake, accessible through the Grand jackpot tier during the bonus rounds.

At Slots Temple, under our Best Slots Odds Guaranteed commitment, we publish Bisonous Fever at the highest available RTP of 96.4%, ensuring players have access to the best available version of the game's maths model.

How to Play

The controls in Bisonous Fever are laid out clearly across the screen:

1. Use the chip stack button to open the bet controls and set your stake. The minimum bet is 20p.
2. Open the three-bar tab to access the paytable, symbol values, and game rules.
3. Press the Spin button to begin each round across the 5x4 grid.
4. Watch for X multiplier symbols on the first reel - each one adds 0.5x to the collect multiplier meter, up to a maximum of 5x.
5. Watch for dynamite pile symbols collecting cash icons - this triggers one of the three hold and win bonus rounds.

How to Win

Bisonous Fever uses a 5x4 grid with 40 fixed paylines, with winning combinations forming when three or more matching symbols land on adjacent reels from left to right starting at the first reel. Five-of-a-kind combinations deliver the highest payline payouts, with the top themed symbol paying 10x the stake for five of a kind. The wild symbol substitutes for all regular paying symbols and pays 25x for five of a kind. Cash symbols and jackpot tokens operate in parallel with the payline structure rather than contributing to standard combination wins.

Top Symbols

The five premium symbols - horseshoe, bell, boot, pistol, and hat - sit at the top of the pay structure, with the highest-paying premium symbol awarding 10x the stake for a five-of-a-kind combination. Card rank symbols make up the lower-paying tier.

The wild symbol has a direct pay value of 25x for five of a kind in addition to its substitution function, making it the highest-paying single symbol in the game. Cash symbols carry displayed values between 0.5x and 50x the stake and are collected by the collector symbol rather than contributing to payline wins.

In Bisonous Fever, the base game operates across three parallel systems: standard 40-payline wins, the cash collect mechanic where a collector symbol on the last reel gathers all visible cash symbol values, and the win multiplier meter on the first reel which applies a running multiplier to wins. Jackpot tokens can also land to build the six progressive jackpot prize values and award them directly.

The three dynamite pile symbols act as the hold and win bonus triggers - when any pile collects a cash symbol, the corresponding bonus round activates. During the bonus, the grid can expand as cash symbols are collected, with the active bonus modifier applying to symbols landing on the unlocked rows.

Collect Win Multiplier

The collect win multiplier operates throughout the base game. Each time an X symbol lands on the first reel, it adds 0.5x to a running multiplier meter displayed on screen. The meter can accumulate up to a maximum of 5x, and its current value is applied as a multiplier to winning combinations and cash collect payouts on the same spin. The meter value persists across spins rather than resetting after each round, meaning it builds over multiple base game spins until a win is multiplied by the accumulated total.

Cash Collect

Cash symbols can land on the first four reels during the base game and on any reel during the hold and win bonus rounds. Each cash symbol carries a displayed value between 0.5x and 50x the stake. These values are collected when a collector symbol lands on the fifth reel during the same spin, gathering the total value of all visible cash symbols on the grid in a single collection event.

The collect win multiplier meter value applies to the collected total at the point of collection, meaning a higher meter value increases the payout from each cash collect event.

Jackpot Prizes

Six progressive jackpot tiers are available in Bisonous Fever, each with its own prize value range. Jackpot tokens can land during the base game to increase the current values of the jackpots and award the corresponding prize when the token's condition is met. Jackpot maximiser symbols - available in all three bonus rounds - can boost any jackpot to its maximum value. The six tiers and their prize ranges are:

Hold and Win Bonus Rounds

Three separate hold and win bonus rounds are available in Bisonous Fever, each triggered by a different dynamite pile symbol collecting a cash symbol during the base game. All three bonuses share the same core respin structure: the feature begins with three respins, and the counter resets to three each time a new symbol lands. The bonus ends when the counter reaches zero or the grid is completely filled. At that point, all accumulated cash values are totalled and paid out alongside any jackpot prizes won.

The bonus rounds begin on a 5x4 grid and can expand as cash symbols are collected. Collecting 8, 12, 16, or 20 cash symbols unlocks one to four additional rows, expanding the grid up to a maximum of 5x8. Cash symbols can land on any reel during the bonus, including on the newly unlocked rows. Mystery symbols can also land in all three bonus rounds and reveal a bonus-specific symbol, a jackpot maximiser, or a cash prize. The specific modifier available during each bonus depends on which dynamite pile triggered the feature:

Vortex Collect

The Vortex Collect modifier is available in one of the three bonus variants. During this feature, special vortex collect symbols can land on the grid. When they do, they accumulate the cash values displayed on any cash symbols visible on the unlocked rows at that point, converting into cash symbols themselves with the collected total as their value. This allows a single vortex collect symbol to gather multiple cash values in one action, consolidating them into a single higher-value cash symbol position on the grid.

Multi Quake

The Multi Quake modifier is available in one of the three bonus variants. During this feature, fire boulder symbols can land on the grid carrying a win multiplier value of 2x to 5x. These multipliers are applied to cash symbols on the unlocked rows, increasing the value of those cash symbols by the boulder's multiplier amount. Multiple fire boulders can land across the same bonus activation, applying their individual multiplier values to different cash symbols on the expanded grid.

Thunderbolt Upgrade

The Thunderbolt Upgrade modifier is available in one of the three bonus variants. During this feature, thunderbolt symbols can land on the grid and increase the prize value of up to four cash symbols on the unlocked rows, then convert into cash symbols themselves. The thunderbolt's own conversion into a cash symbol means it contributes to the grid's total cash symbol count in addition to upgrading existing values, supporting both the collection total and the grid expansion threshold simultaneously.

Bisonous Fever Slot – Summary

Bisonous Fever is a structured slot built around a three-variant hold and win bonus system on an expanding grid, supported by a base game with a parallel cash collect mechanic, a progressive multiplier meter, and six jackpot tiers. The medium volatility, 96.4% RTP, and 10,000x maximum win position this within the mid-range of the Games Global and Foxium catalogue, with the Grand jackpot tier and the bonus round modifiers carrying the game's top-end pay potential.

Within the Games Global and Foxium catalogue, Bisonous Fever uses a hold and win respin format with an expanding grid system and multiple modifier variants - a more layered structure than single-modifier hold and win titles. The three-variant bonus system, where each dynamite pile triggers a different modifier during the same core respin framework, is a structural approach that differentiates individual bonus activations without introducing entirely separate feature formats.

Compared to simpler hold and win slots with a fixed grid and a single bonus mechanic, Bisonous Fever's expanding grid up to 5x8 and the three modifier variants give the bonus phase more structural variability across activations. The six-tier jackpot system - spanning from 2x at the Mini level to 10,000x at the Grand level - covers a wider prize range than many comparable hold and win titles with two or three jackpot tiers.
