How the Big Bonus Feature Works

  • Bonus symbols may appear on any reel in the main game.
  • Achieve 3 or more Bonus symbols anywhere on the reels to trigger the Big Bonus.
  • The Big Bonus value is chosen in a pick-me round and depends on the number of triggering Bonus symbols:
    • 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 Round

  • Players are presented with 6, 9, 12, or 15 identical tiles, based on how many Bonus symbols triggered the feature.
  • Choose tiles to reveal hidden Big Bonus gems.
  • When three matching gems are found, the Big Bonus feature begins at the corresponding value.

Free Spins and Booster Gems

  • The bonus trail from the pick-me feature continues into the free spins round.
  • Landing Big Bonus Booster gems on the sixth reel will add to your current trail.
  • Filling the active trail segment with Booster gems upgrades the Big Bonus value.
  • Only Booster gems from the current trail segment are available to land on reel 6.
  • Any Wild symbols during free spins become locked until the feature concludes.
  • Free spins continue until a single win meets or exceeds the Big Bonus value.

  • While active, the bonus is triggered 50% more frequently.
  • The main awards, eligible bonus values, and thresholds remain the same as during standard play.

The Gamble Feature

  • The gamble feature can be set to on, on if the win is 5x stake or higher, or off.
  • When active, any win can potentially launch the gamble; if the win is at least 5x your bet, the gamble is also offered.
  • Players are given two wheels:
    • The left wheel allows the chance to increase winnings by half, double, or triple.
    • The right wheel provides the opportunity to win entry into the Big Bonus, with an adjustable win value.
  • If the pointer lands on green, the corresponding prize is paid; if it lands on red, winnings are lost.
  • Winnings may be gambled up to x2500 the base stake or £50,000, whichever is lower.
  • A maximum of 6 Scatters can be achieved on the gamble’s Bonus wheel.
