The stakes are piled high under the sea in PlayTech’s online slot Great Blue. Don’t let the adorable fish fool you into thinking this is a game for guppies because the sharks will soon rear their heads and help you chase some big winnings. The ocean is truly a place of riches and now you have the opportunity to explore them from the comfort of your own sofa. No scuba gear required!


You’ll notice this is a popular online slot game with high-rollers. The number of pay-lines may be average at 25 but the bet per line can run up to £1,000 with a maximum coin size of £100, making the maximum you can stake on a single spin a whopping £25,000. Punters looking for a slower start needn’t worry as you can easily change the coin size to £0.01, giving you a minimum bet of just £0.25 per spin on Great Blue. There are plenty of possibilities and fish to be caught!

When looking at the symbols available, no less than 11 regular symbols can be found across the reels. The larger the sea creature, the bigger the pay-out with sharks and turtles fetching 750 times your line bet when you line up five of them. A surprising feature are the generous small pay-outs. You need to match just two bubbly 9’s to win double your bet per line. Watch out for the Killer Whale as he’s the Wild, doubling your wins while at the same time being the highest paying symbol. Since the Wild substitutes for all other symbols apart from the Scatter, having this dangerous animal on your side could really boost your chances of winning.

However, it’s the oysters who can really make your spin worth it. As the Scatter symbol, just two anywhere across the reels is enough to snag you a small pay-out. Get three or more to activate the bonus round where 8 free spins are waiting for you alongside a x2 multiplier. You’ll be presented with five sea shells and get to pick two to reveal more free spins and multipliers which can reach a maximum of 33 or x15. Even more exciting is the fact you can retrigger the free spins infinitely! If at any point during the bonus game you get another three or more Scatters, you receive 15 more at the same multiplier as the triggering spin. The bounty really is as boundless as the sea in Great Blue!

Also worth mentioning for this online slot is the additional ‘Gamble’ feature which you can access by clicking the relevant button after a winning spin. This option allows you to stake what you’ve just won with a chance to double your money if you guess the colour of the next card. Simply choose red or black to gamble or click on ‘collect’ to add your winnings to your balance and return to the main game.

Dive into the wonderful world of SuperCasino when playing Great Blue and you might just dig up a treasure. With great flexibility to adjust your bet per line and a large amount of symbols that could score you a winning spin, this online casino game is surely a winner for high-rollers and adventurous players.
