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.

• 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.

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.
