The Great Blue slot by PlayTech is a visually retro casino game. But it has its merits and the potential for infinite free spins. It’s not a game for everyone, especially if you prefer flashier slots, but it’s the perfect game for classic slot lovers.

Great Blue Slot Features

The Great Blue slot features are what makes this game exciting and worth some attention. It might not be able to compete in terms of graphics but there’s definitely more to it than meets the eye. Deep beneath the surface lie the special symbols that can trigger a whole school not of fish but of bonus games and perks. The Scatter sea shell symbol is the one to look out for! Here’s what is hidden under the shell:

Sea Shell Bonus GameDuring the free spins mode, you’ll be able to choose 2 out of 5 seashells with hidden rewards. Those can be more free spins or multipliers, or both. You can win up to 33 free spins and a 15x multiplier.
Free SpinsLanding three or more of the Sea Shell scatter symbols automatically grants you 8 Great Blue free spins with a 2x multiplier!
Infinite Free SpinsThe Great Blue free play can be re-triggered. If you land 3 or more Scatter symbols during free spins, you’ll win another 15 with the same multiplier of the spin that re-triggered them. And then again. And again! And again, if you’re lucky enough to continue landing 3 or more Scatters.

Winning Symbols

Get ready to dive among rewarding symbols encompassing marine life when you start the Great Blue slot game. The payouts are in coins. The monetary equivalent you’ll get on a winning spin depends on your bet per line and the number of paylines that are active.

Low-Paying Symbols


These are the well-known card symbols 9, 10, J, Q, K, A. 9 is in a category of its own because it makes payouts even in combinations of 2 of-a-kind. The rest need to be 3 of-a-kind to secure a payout.

Medium-Paying Symbols


Those are the yellow tropical fish, the seahorse, and the purple starfish. 3 of-a-kind of the latter two payout 15, while of the first – 20. Yes, the tropical yellow fish is more rewarding.

High-Paying Symbols


Those are the sea turtle and the shark! They make payouts even when you land just 2 of a kind on an active payline.

Special & Highest-Paying Symbols – those are the Wild and the Scatter. The Wild symbol is the orca killer whale, and it can substitute for every symbol except for the Scatter. The Scatter is the seashell, and it’s the one triggering the bonus game and free spins!

You can see all the symbols in the screenshot below.

Great Blue Slot Design & Graphics

The Great Blue slot’s game design and graphics have a retro touch to them. You’ll dive into an ocean of vibrant colours and rounded corners wrapped up nicely with subtle retro sounds. But as we said, there’s more to this game than meets the eye. Beneath the surface lurks HTML5 technology that ensures a high-quality experience even when you gamble on the go.


Great Blue Slot Gameplay

The Great Blue slot game is not just vibrant colours and ocean breeze. The 5-reel retro slot by PlayTech has 25 adjustable paylines and a theoretical RTP of 96.03%. The adjustable paylines make the game ideal for players with smaller budgets. Your total bet is you bet per line multiplied by the number of active lines.

You can drop that number down to 1. In that case, the minimum bet you can place is £0.01, whereas the maximum would be £2. If you activate all of the paylines, your total minimum bet would be £0.25, and the maximum – £50.
