Great Blue Jackpot is the progressive jackpot version of Playtech’s classic slot – with 5 reels and 25 paylines, it can be played from as 25p to £12.50 per spin on all devices. The highly volatile game gets a makeover and comes with a superb Pearl Bonus feature where you can begin with up to 33 free spins with a 15x multiplier. With unlimited free spins to be won, you can also win 1 of 4 progressive jackpots.

Visually, it’s very similar to the original, Great Blue – it does crisper graphics and animations though. With the same breezy soundtrack, you are taken to the ocean where you encounter marine life. Symbols on the reels include A, K, Q, J, 10 and 9 playing cards (in a bubbling water style) – you’ll also see starfish, sea horses, tropical fish, turtles and sharks. The latter is the most rewarding giving you 30 times your stake for 5 across a payline.

The whale is the wild symbol and substitutes for all symbol bar the scatter – when a wild is part of a winning combination, it will double your win. For example, if you were to get 4 shark symbols as well as a wild on a payline, you’d win 60 times your stake as opposed to 30 (for 5 sharks). The whale wild can land stacked on all reels – 2, 3, 4 or 5 on a payline will give you 0.4, 10, 100 or 400 times your stake!

The scatter is the seashell and pearl symbol – 2, 3, 4 or 5 on a payline will reward you with 2, 5, 20 or 200 times your total stake respectively. If you get 3 or more, you will activate the Pearl Bonus feature. Beginning with 8 free spins and a 2x multiplier, you pick 2 out of 5 seashells to win additional free spins and/or multipliers.

There’s up to 33 free spins and multipliers up to 15x available! Look out for the scatter appearing during the feature as 3 landing simultaneously on a free spin will reward you with 15 additional free spins. There’s no limit to how many times you can retrigger the feature giving you the possibility of infinite free spins.

The game also comes with a Great Blue Jackpot feature which is triggered randomly on any base game spin – you then enter the jackpot game where you’re guaranteed to win 1 of 4 progressive jackpots. You need to pick coins with 3 identical ones giving you the corresponding jackpot – in ascending order of value, you have the Fish, Turtle, Shark and Whale jackpots.

Great Blue Jackpot is almost identical to the cult favourite Great Blue but with a progressive jackpot element – with sharper graphics and animations, you can still win the same amount of free spins and multipliers. The payouts for the symbols is also the same. Adding 4 progressive jackpots to the mix is a good move by Playtech as the original is 1 of the most popular online slots ever!
