Jackpot Diamonds

The Jackpot Diamonds Feature uses the four-level Diamond Mystery™ Jackpot feature. Each mystery level has specific gems.

The base win of each jackpot depends on your stake. The base win is 5,000x your stake for the Diamond Jackpot, 1,250x your stake for the Red Gem Jackpot, 200x your stake for the Blue Gem Jackpot, and 50x your stake for the Green Gem Jackpot.

  • Green Gem – 1st level (lowest jackpot value)
  • Blue Gem – 2nd level
  • Red Gem – 3rd level
  • Diamond – 4th and highest level

Once triggered, the player is taken to the Jackpot Cards game where he/she can pick one of 12 face-down cards. The player picks cards until 3 matching gem symbols have been revealed. The Jackpot Diamonds Mystery level corresponding to the revealed gems will be awarded.
