To win one the four available progressive jackpots, you must randomly trigger the jackpot side-game. This is a coin icon pick ‘em game with 20 concealed symbols that each correspond to one of the jackpots. You uncover icons and when you ill up the power bars with one matching icon, that decides which progressive jackpot you win. Your jackpots are: Whale, Shark, Turtle, and Fish.


Coins start from 1p and go up to 50p, so your minimum possible bet is 1p while your biggest possible bet is £12.50.

The whale is your wild and as well as substituting other icons for wins with a 2x multiplier attached, it also pays the biggest standard (non-jackpot) payout on your game of between 10x and 10,000x your stake, when you match between 2 and 5 in a row on an active payline.

The shark symbol pays the next biggest win for 5 in a row, with a win of 750x your stake awarded.

The seashell is your scatter on Great Blue Jackpot and it will trigger the Pearl bonus feature when you land 3 anywhere in sight on a single spin. You start with 8 bonus spins and a 2x multiplier, but before the feature starts, you have the opportunity to increase this via a pick ‘em game:

  • Choose 2 of the available seashells to see if you have added extra bonus spins or multipliers.
  • You can win up to 33 bonus spins and multipliers up to 15x.
  • Land 3 more scatters during bonus spins and win an additional 15 bonus spins with a 2x. multiplier
  • Your total bonus spins can be unlimited.


The graphics and animations on this Playtech-designed online slot are impressive on mobile or desktop devices, with a range of sound and game speed options to personalise the way you play. If you haven’t yet experienced mobile gaming, you can expect incredible sound effects that suit headphone usage perfectly, with intuitive software that matches the functionality of your chosen mobile device, plus premium graphics that are crisp, clear, and stylish. All this combined means that while on the move, your online slots experience is fun, reliable, and the best possible quality.


For cash payouts when you win, and the chance to claim one of the 4 different progressive jackpots, you must place bets using real money – which means you need to create an account and make a deposit into a UK recommended online casino’s bankroll. Once your bankroll is loaded with funds, you can play Great Blue Jackpot from 1p a spin.


Great Blue Jackpot is a game with plenty of style but also big win potential. A great choice for online slots players who also enjoy nature and the ocean – the sound effects are top class – while the potential payouts, including 4 progressives and a 10,000x your stake top standard win, are truly impressive.
