Features and Special Symbols

Wild Symbol

  • The Wild symbol can stand in for any other symbol except the Bonus Scatter to help create winning combinations.
  • During the main game, Wilds can land on all six reels. In the Free Spins Bonus, they appear only on reels 2, 3, 4, and 5.
  • For the duration of free spins, any Wild that appears is locked in place until the feature ends.

Big Bonus Entry

  • Bonus symbols can land on every reel during normal play.
  • When three or more Bonus symbols appear anywhere in view, the Big Bonus feature is triggered.
  • The starting Big Bonus value is set by the Match 3 Pick Me round according to the number of Bonus symbols:
    • 3 Bonus Symbols: Possible values are 20X, 25X, 30X, 50X, or 100X.
    • 4 Bonus Symbols: Possible values are 25X, 30X, 50X, or 100X.

Big Bonus Match 3 Pick Me

  • This round determines the Big Bonus starting value, with a selection of 6, 9, 12, or 15 tiles shown, based on the number of triggering Bonus symbols.
  • Players pick tiles to reveal Big Bonus gems, and matching three of the same gem sets the initial value for the bonus.

Free Spins and Big Bonus Booster Mechanics

  • The Big Bonus trail established in the pick-me round carries into the free spins feature.
  • Big Bonus Booster gems may appear on reel 6 during free spins, adding to the current trail segment.
  • Completing the active trail segment with Booster gems upgrades the Big Bonus value.
  • Only gems relevant to the current trail segment are present on reel 6.
  • Wild symbols that land during free spins lock in position until the end of the feature.
  • Free spins continue until a win equalling or exceeding the Big Bonus value is achieved.

Gamble Feature

  • The gamble setting allows for three options: fully on, on only for wins of 5x stake or more, or off entirely.
  • When available, the gamble feature presents two wheels:
    • The left wheel offers the potential to increase the win by half, double, or triple it.
    • The right wheel gives a chance to gain entry to the Big Bonus, with the win value adjustable before spinning.
  • If the pointer lands on green, either the cash prize or bonus entry is accepted; if on red, the current winnings are lost.
  • The maximum gamble outcome is either 2,500 times the base stake or £50,000, whichever is lower.
  • A maximum of 6 Scatters applies when gambling for entry to the bonus feature.
  • The option to collect winnings at any time is available by pressing ‘COLLECT’.
  • The expected value for gambles is shown within the game.

Spin Chance

  • Spin Chance activates if the remaining credit falls below the stake required for a spin, but is above zero.
  • Players may choose to wager their remaining credit for a single spin at the current bet, or exit and keep their balance.
  • If the pointer stops on green, a spin is awarded; if on red, the remaining credit is lost.
