Developed by Games Global Studio, Bisonous Fever is a video slot game featuring 5 reels and 4 rows. With a fixed layout and 40 paylines, each spin offers a variety of potential winning combinations. 
How to Play

Payline and Winning Rules
- There are 40 fixed paylines in every spin.
- Paylines are formed by matching symbols on adjacent positions, beginning from the leftmost reel and paying left to right only.
- Only the highest win on each payline is paid; multiple payline wins in a single spin are added together for the total payout.
- The paytable illustrates payout values for every symbol combination based on your current bet.
- The displayed ‘win up to’ amount approximates the maximum possible result from a single spin, rounded down.
Bet and Payout Details
- Each spin is played at the current selected total bet.
- The initial bet is calculated as your total bet divided by 10.
- Payline wins are determined based on the initial bet and the winning symbol combination.
Special Features and Mechanics
Collect Feature
During the base game, landing a Collect symbol on reel 5 awards the total value of all visible cash symbols on the reels. This feature can trigger at any spin when these conditions are met.
Collect Multiplier
- The Collect Multiplier bar begins at 1x.
- Every X symbol that lands on reel 1 increases the multiplier by 0.5x, up to a maximum of 5x. Once at 5x, X symbols no longer appear.
- When a Collect symbol gathers cash symbols, the current multiplier is applied and then resets back to 1x.
- If a Collect symbol lands without any cash symbols present, the multiplier remains unchanged.
Cash Symbols
- Cash symbols can land on reels 1-4 during the base game.
- Cash symbols award between 0.5x and 50x your bet, regardless of their colour.
- In bonus games, cash symbols may appear on any reel.
Collect Symbol
The Collect symbol can land on reel 5 in the base game, enabling the Collect Feature.

- Mini Jackpot: increments by 0.5x bet
- Minor Jackpot: increments by 1x bet
- Maxi Jackpot: increments by 2x bet
- Major Jackpot: increments by 4x bet
- Mega Jackpot: increments by 5x bet
- Grand Jackpot: increments by 10x bet
- In bonus games, Bonus Jackpot tokens are tied to landed cash symbols and colours.
- The number of tokens collected during bonus games determines Jackpot prizes:
- 1 Bonus Jackpot token (relevant colour): Mini Jackpot
- 2 tokens: Minor Jackpot
- 3 tokens: Maxi Jackpot
- 4 tokens: Major Jackpot
- 5 tokens: Mega Jackpot
- 6 tokens: Grand Jackpot

Bonus Game Features
Three different bonus games can be triggered from the base game when a matching cash symbol is collected to a dynamite pile. This visual collection of cash symbols is for entertainment purposes only and does not affect the triggering of features.
- All bonus games start with 3 spins and are originally played on a 5×4 grid.
- The grid can expand up to 5×8 by unlocking up to 4 extra rows.
- Initially, the top 4 rows are locked; unlocking occurs by collecting cash symbols:
- 8 cash symbols unlock 1 additional row
- 12 cash symbols unlock 2 rows
- 16 cash symbols unlock 3 rows
- 20 cash symbols unlock all 4 rows
- Every time a cash symbol lands, the spin counter resets to 3.
- The bonus round ends when all spins are used, or every position is filled.
