How Big Bonus Booster Works

Big Bonus Booster is a six-reel slot game created by Inspired, featuring 50 paylines. Players can select bet amounts ranging from £0.10 to £5.00 per spin. Winning combinations are formed by landing three or more matching symbols on adjacent reels, starting from the leftmost reel and following one of the active win lines.

Reels and Paylines

• The slot has 6 reels and 50 fixed paylines.
• All wins are paid left-to-right, except for Bonus symbols.
• Only the highest win on each payline is paid, while wins on different lines are added together.

Symbols and Their Values

Payouts depend on the symbol and the number landed on a payline. The following list shows the awards for each symbol based on the bet level:

• Wild: 6x = £250, 5x = £15, 4x = £4, 3x = £1

Big Bonus Feature

How to Trigger Big Bonus

• Bonus symbols can land on any reel during the main game.
• Landing three or more Bonus symbols anywhere on the reels activates the Big Bonus feature.
• The value of the Big Bonus is set by a pick-me round:
  • 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

Big Bonus Match 3 Pick Me

• The pick-me round presents 6, 9, 12, or 15 identical tiles based on the number of triggering Bonus symbols.
• Select tiles to reveal Big Bonus gems; matching three of the same gem starts the Big Bonus at that value.

Free Spins and Bonus Booster

• During free spins, the Big Bonus trail established in the pick-me round is maintained.
• Big Bonus Booster gems may appear on reel 6, increasing progress along the trail.
• When the current trail segment is filled with Booster gems, the Big Bonus value is upgraded.
• Only the gems corresponding to the active trail segment are present on reel 6.
• Wild symbols that land during free spins remain locked in their positions until the end of the bonus.
• Free spins continue until a single win meets or exceeds the Big Bonus value.

Fortune Bet Mode

• Fortune Bet can be switched on or off, altering the gameplay.
• When Fortune Bet is active, the chance to trigger the bonus feature increases by 50%.
• All prize amounts, Big Bonus values, and thresholds stay the same as with the base stake.

Gamble Feature

• The gamble can be configured to always be available, only when wins are 5x the stake or more, or turned off entirely.
• When active, any win can initiate the gamble feature; for wins of 5x stake or greater, the gamble is always offered.
• There are two gamble wheels:
  • The left wheel gives the option to increase winnings by half, double, or triple.
  • The right wheel offers a chance at entering the Big Bonus; players can adjust the value here.
• If the wheel pointer lands on green, the prize or bonus is awarded; landing on red means winnings are lost.
• Winnings may be gambled up to a maximum of x2500 the base stake or £50,000, whichever comes first.
• Up to 6 Bonus Scatters may be collected on the gamble bonus wheel.
• Players may choose to collect winnings at any point.
• The expected payback for the gamble is displayed within the game.

Spin Chance

• If available credit falls below the cost of a spin but remains above zero, Spin Chance is offered.
• Players may choose to wager the remaining credit for one spin at the current bet level.
• Choosing 'PLAY' triggers a pointer; landing on green awards a spin, while red forfeits the remaining credit.
• Alternatively, 'NO THANKS' lets players exit and keep their remaining credit.
