Special Features

Cash Infinity™

  • Cash Infinity™ symbols may randomly appear in the base game and stick to the reels until the end of the Hold the Jackpot™ Bonus Game.
  • All sticky Cash Infinity™ symbols are locked in place while other symbols are spun.
  • When a sticky symbol appears, the outcome of remaining non-sticky symbols is entirely random.
  • Cash Infinity™ symbols award prizes ranging from 5x-15x player’s bet. However, the prize will be paid at the end of the Bonus Game.
  • If the Cash Infinity™ symbol is drawn on the middle row of the reels, it increases the chances of activating the Hold the Jackpot™ Bonus Game.
  • Cash Infinity™ symbols are temporarily removed from the reels when changing bet levels and Volatility Level™ and only appear on the bet level and Volatility Level™ they were obtained on.

Hold the Jackpot™ Bonus Game

  • All Bonus symbols stick to the reels during the Bonus Game.
  • 3 re-spins are granted at the beginning of the Bonus Game.
  • Each new Bonus symbol resets the number of re-spins to 3.
  • The Bonus Game continues until re-spins are finished, or all reels are filled with Bonus symbols.
  • Cash symbols award prizes ranging from 1x-10x player’s bet.
  • MINI, MINOR and MAJOR Jackpot symbols may randomly appear during the Bonus Game and award corresponding Jackpots. Multiple Jackpots of the same type may be won during the Bonus Game.
  • Collector symbol accumulates all values from Cash and Cash Infinity™ symbols and multiplies them randomly by 1-20x.
  • Mystery symbol can transform into any other Bonus symbol, apart from Cash Infinity™ symbols.
  • Jackpot Mystery symbol can only transform into MINI, MINOR and MAJOR Jackpot symbols.
  • Mystery and Jackpot Mystery symbols open one by one at the end of the Bonus Game.
  • When the Bonus Game ends, the prize is paid for the sum of Bonus symbol values, including MINI, MINOR, MAJOR Jackpots, unless the GRAND Jackpot is won.
  • Bonus symbols pay only at the end of the Bonus Game.
  • Collecting all 15 Bonus symbols of any type awards the GRAND Jackpot of 2000x player’s bet.
  • The GRAND Jackpot is the maximum potential prize in the game and Bonus symbol values are not added to it.
  • Hold the Jackpot™ Bonus Game is played at the same bet level and Volatility Level™ as the spin that activated the bonus.

Chance Level™

  • The game is played with the base bet set by default.
  • However, the Chance Level™ feature can be enabled during the base game and you can select one of 4 levels:
    • Chance Level™ x2 – the base bet is multiplied by 2, giving you a 2x higher chance of activating the Hold the Jackpot™ Bonus Game.
    • Chance Level™ x4 – the base bet is multiplied by 4, giving you a 4x higher chance of activating the Hold the Jackpot™ Bonus Game.
    • Chance Level™ x6 – the base bet is multiplied by 6, giving you a 6x higher chance of activating the Hold the Jackpot™ Bonus Game.
    • Chance Level™ x10 – the base bet is multiplied by 10, giving you a 10x higher chance of activating the Hold the Jackpot™ Bonus Game.
  • The Chance Level™ feature does not affect the paytable, thus symbol values remain the same as for the base bet in both the base game and the Bonus Game.
  • Sticky symbols are temporarily removed from the reels when changing Chance Level™ and only appear on the Chance Level™ they were obtained on.

Malfunction voids all pays and plays.

Return to Player (RTP): The RTP is shown in-game.

  • After activating the Gamble feature, a player can:
    • take the win and end the Gamble feature,
    • continue playing the Gamble feature by selecting one of the two symbols.
  • After selecting a symbol, a draw is made to determine the winning symbol.
  • Each draw is independent of the previous one and has the same probability of winning.
  • The player can end the Gamble feature after each round.
  • In the event of a loss, the player loses the win value specified in the current win counter and returns to the main game.
  • The Gamble feature can be played for a total of 7 rounds.
