Exploring Wild Symbols

- In the main game, Wilds can appear on any reel. During the Free Spins Bonus, Wilds are restricted to reels 2, 3, 4, and 5.
- When a Wild appears during free spins, it will remain locked in place until the end of the feature.
How Win Lines Work
- Big Bonus Booster offers 50 paylines, providing multiple opportunities for combinations in each spin.
- Winning combinations must start from the leftmost reel and progress along adjacent reels, except for Bonus symbols.
- Only the highest win on each payline is paid, while wins across different lines are added together.
Triggering the Big Bonus Feature
- Bonus symbols can land on any reel during the base game.
- Landing three or more Bonus symbols anywhere on the reels triggers the Big Bonus feature.
- The starting value of the Big Bonus is determined during the pick-me round, based on the number of Bonus symbols that activated the feature:
- 3 Bonus Symbols: 20X, 25X, 30X, 50X, or 100X
- 4 Bonus Symbols: 25X, 30X, 50X, or 100X
- 5 Bonus Symbols: 30X, 50X, or 100X
- 6 Bonus Symbols: 50X or 100X
The Big Bonus Match 3 Pick Me Round
- This round determines the value at which the Big Bonus begins.
- The game reveals a selection of 6, 9, 12, or 15 identical tiles, based on how many Bonus symbols triggered the feature.
- Players choose tiles to uncover Big Bonus gems. Revealing three matching gems awards the corresponding value and activates the bonus.
Free Spins and Progressive Trail
- The Big Bonus trail established during the pick-me round carries over into free spins.
- Big Bonus Booster gems may appear on reel 6, adding to the active trail segment.
- Completing the current trail segment with Booster gems upgrades the Big Bonus value.
- Only gems relating to the active part of the trail can land on reel 6 during the feature.
- Wild symbols that appear while free spins are active will lock in place for the remainder of the bonus.
- Free spins continue until a win equal to or above the current Big Bonus value is achieved.
Fortune Bet Mode
- Fortune Bet can be activated manually through the game controls.
- While this mode is active, the chance of triggering a bonus increases by 50% compared to standard play.
- All payouts, starting Big Bonus values, and other thresholds remain the same as the base stake.
The Gamble Feature
- The gamble feature can be set to one of several states: on, on if the win is 5x stake or more, or off entirely.
- When active, players can choose to gamble any qualifying win. If the win is at least 5 times the stake, the gamble feature is available regardless of settings.
- There are two gamble wheels:
- The left wheel offers options to increase winnings by half, double, or triple the amount.
- The right wheel provides a chance to enter the Big Bonus; the win value can be adjusted before spinning.
- If the pointer lands on green, the displayed prize or bonus is awarded. If it lands on red, the winnings for that gamble are lost.
- Players may gamble up to 2500 times the base stake or a maximum of £50,000, whichever limit is lower.
- No more than six Bonus Scatters can be achieved in the gamble related to the Bonus wheel.
- Players can press 'COLLECT' at any time to secure their current winnings.
- The return to player (RTP) for the gamble feature can be viewed in-game.
Spin Chance Mechanic
- If the player’s credit falls below the current bet but is still above zero, the Spin Chance becomes available.
- This feature allows a chance to wager all remaining credit for another spin at the current stake.

Big Bonus Booster Strategy
There is no Big Bonus Booster strategy that can guarantee a win. Like other online slots, the outcome of each spin is determined randomly, so previous results do not influence what happens next.
The most useful Big Bonus Booster strategy is to understand how the slot works before playing. Check the RTP, volatility, paylines and available features so you know what to expect from the game. These details can help you decide whether Big Bonus Booster suits your preferences, but they do not increase your chances of winning on an individual spin.
