Bisonous Fever Slot
What Is Bisonous Fever?
Bisonous Fever is a 5-reel, 4-row online slot game provided by Games Global Studio. The game highlights winning combinations directly on the reels and awards payouts accordingly. 
How Do the Paylines Work?
Bisonous Fever features 40 fixed paylines. Each payline is a distinct pattern of adjacent symbol positions that runs across the reels. Only paylines starting from the leftmost reel and continuing to the right on adjacent reels are valid. Wins are formed when matching symbols land on a payline in adjacent positions from left to right. The number of paylines played is always fixed at 40.
What Are the Bet Options?
You can choose your total bet for each spin, with options ranging from £0.20 up to £5.00 per spin. The initial bet amount is calculated by dividing your current total bet by a payline cost of 10. The current bet amount is clearly displayed, and you can adjust it using the bet button. 
How Are Payouts Calculated?
Payouts on paylines are based on the initial bet placed. The payout amount depends on the specific symbol combination that forms a win. When multiple winning combinations occur on a single payline, only the highest win on that payline is awarded. The total payout is the sum of all payline wins from one spin. The paytable shows the current payout of each symbol combination relative to your bet amount. The displayed ‘win up to’ value is the highest potential win on a single spin, rounded down for display purposes.
What Is the Collect Feature?
If a Collect symbol appears on reel 5, the total value of all cash symbols currently visible on the reels is awarded instantly. This feature can trigger during the main (base) game.
How Does the Collect Multiplier Work?
At the start, the Collect Multiplier bar is set to 1x. Every time an X symbol lands on reel 1, the multiplier increases by 0.5x, up to a maximum of 5x. Once the top value is reached, the X symbol no longer appears. When a Collect symbol collects cash symbols, your current multiplier is applied to the total and then the bar resets to 1x. If a Collect symbol lands when there are no cash symbols in view, the multiplier bar remains unchanged.
What Are Cash Symbols?
Cash symbols can boost your winnings. These symbols may be of any colour and can award between 0.5x and 50x your bet. During the main game, cash symbols can appear on reels 1–4. In bonus games, they may land on any reel.
What Is the Role of the Collect Symbol?
The Collect symbol may land exclusively on reel 5 during the main game. When it appears, it interacts with any cash symbols present, activating the Collect Feature as described above.
How Do Jackpot Tokens Function?
Base Jackpot tokens may appear on any reel during the main game. Each token boosts the value of its corresponding Jackpot:
- 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, collecting a certain number of Bonus Jackpot tokens of the relevant colour will award the corresponding Jackpot:
- 1 token: Mini Jackpot
- 2 tokens: Minor Jackpot
- 3 tokens: Maxi Jackpot
- 4 tokens: Major Jackpot
- 5 tokens: Mega Jackpot
- 6 tokens: Grand Jackpot
Jackpot values are directly linked to your current bet amount and can only be won during bonus games.
What Jackpots Are Available?
Bisonous Fever offers six Jackpots:
- Mini Jackpot: 2x – 10x bet
- Minor Jackpot: 8x – 25x bet
- Maxi Jackpot: 10x – 50x bet
- Major Jackpot: 20x – 100x bet
- Mega Jackpot: 500x – 2,500x bet
- Grand Jackpot: 5,000x – 10,000x bet
The specific jackpot values will scale according to your stake during bonus games.
How Do Bonus Games Work?
There are three unique bonus games that can be triggered while playing the main game. Bonus games are triggered by collecting a matching cash symbol into a dynamite pile. The graphical collection of cash symbols is decorative and has no effect on feature triggering.
You start each bonus game with 3 spins on a 5×4 grid. This grid can be expanded up to a 5×8 grid, unveiling up to 4 extra rows. Initially, only the bottom 4 rows are unlocked. Rows are unlocked by collecting cash symbols:
- 1 additional row: 8 cash symbols collected
- 2 additional rows: 12 cash symbols collected
- 3 additional rows: 16 cash symbols collected
- 4 additional rows: 20 cash symbols collected
Whenever a cash symbol appears, the spin counter resets to its initial value. The bonus round ends when you run out of spins or fill all grid positions.
What Symbols Appear in Bonus Games?
Several special symbols appear during bonus games:
- Cash symbols (may appear even on locked rows)
- Vortex Collect symbol: exclusive to the Vortex Collect Bonus Game
- Fire Boulder symbol: exclusive to the Multi Quake Bonus Game
- Thunderbolt symbol: exclusive to the Thunderbolt Upgrade Bonus Game
- Jackpot Maximiser symbol: increases bonus game jackpots to their maximum value
- Mystery symbol: can reveal a cash symbol, a Jackpot maximiser, or a special symbol unique to the current bonus game
Only unlocked cash symbols are eligible for special symbol effects. All bonus game symbols will also reset the spin counter to its initial value.
What Is the Vortex Collect Bonus Game?
This bonus game features purple cash symbols. The Vortex Collect symbol may appear on any unlocked reel and, when landed, gathers the value of all unlocked cash symbols. The Vortex Collect then transforms into a cash symbol displaying the accumulated value. Purple ribbons identify cash symbols with accumulated values. Only one Vortex Collect symbol can land per spin, but several can appear during the bonus game.
What Happens in the Multi Quake Bonus Game?
Multi Quake uses red cash symbols. The Fire Boulder symbol, which may only land once per spin but can appear in several spins, features multipliers of 2x, 3x, 4x, or 5x. It multiplies the value of all golden cash symbols on unlocked reels. Red ribbons highlight these multiplied cash symbols. The Fire Boulder symbol disappears after applying its effect and does not persist to the following spin.
How Does the Thunderbolt Upgrade Bonus Game Operate?
In this game, blue cash symbols are active. On any given spin, the Thunderbolt symbol may land once and will increase the value of 4 random cash symbols on unlocked reels. If fewer than 4 cash symbols are present, each receives the increment. Blue ribbons appear on upgraded symbols. After awarding its increments, the Thunderbolt symbol transforms into a new cash symbol with a random value.
How Do Wild Symbols Work?
Wild symbols help form winning combinations by substituting for other symbols, except for Cash, X, and Collect symbols. This can improve your chances of achieving a win on a payline.
