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-10x 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 only appear on the bet level they were obtained on. Playing a game round on another bet level removes Cash Infinity™ symbols from the reels completely.

Hold The Jackpot Bonus Game

• All Bonus symbols stick to the reels during the Bonus Game.
• 3 Respins are granted at the beginning of the Bonus Game.
• Each new Bonus symbol resets the number of Respins to 3.
• The Bonus Game continues until Respins are finished, or all reels are filled with Bonus symbols.

• 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.

• Bonus symbols pay only at the end of the Bonus Game.
• Collecting all 15 Bonus symbols of any type awards the GRAND Jackpot of 1000x player’s bet.
• The GRAND Jackpot is the maximum 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 3 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™ x3 – the base bet is multiplied by 3, giving you a 3x higher chance of activating the Hold the Jackpot Bonus Game.
  • Chance Level™ x5 – the base bet is multiplied by 5, giving you a 5x 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.

The RTP value is shown in-game. Malfunction voids all pays and plays.

Gamble Feature (Where Available)

• The Gamble feature gives a chance to double each win.
• The Gamble feature can be activated only with the current win value during the ongoing game session.

  • 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.
• 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.
