The Great Blue Jackpot is a mystery multi-level progressive jackpot game. The progressive jackpot is accumulated by all the Casinos that offer the Great Blue Jackpot™ game. A small percentage of every bet (called the ‘contribution rate’) that is placed by every person eligible to win the Great Blue Jackpot in various online Casinos is added to the progressive jackpot pool. There are 4 different jackpots that can be won: Dark Blue (Whale), Light Blue (Shark), Green (Turtle) and Yellow (Fish). The different jackpot levels hold different prize amounts.

The trigger that starts the jackpot game can randomly occur on any main game spin including losing spins. A bet of any size can trigger the jackpot game, but the higher your bet, the bigger your chance to enter the jackpot game. Entering the jackpot game guarantees a win of 1 of the 4 jackpots.

Click CLICK TO START to enter the Great Blue Jackpot. At the end of the jackpot game, a win screen displays your winnings. Click CONTINUE to return to the main game.

The Great Blue Jackpot works like this:

Seed (how much money the jackpots start out with):

Dark Blue (Whale): €40,000
Light Blue (Shark): €2,000
Green (Turtle): €200
Yellow (Fish): €20

The jackpot game screen contains 20 coins, each of which hides 1 of the 4 jackpot symbols. Clicking on a coin flips it and reveals the jackpot symbol. Once 3 matching symbols have been found, the player wins the corresponding jackpot. The Great Blue Jackpot game has a timeout timer (30 second). If the player fails to find three matching symbols before the time runs out, the game is automatically played to reveal the player’s prize. Jackpot winnings are added to the main game winnings (if any) and displayed in the Win popup together with any other winnings.
