As humans, we’ve merely seen about 5% of what the ocean has to offer. If you’re curious about what’s going on down there and you enjoy playing casino games, then we’ve got a really good recommendation for you – Great Blue. The game has relaxing background music, configurable paylines, and a number of bonus features. However, when it comes to picking a slot, there are more to consider – which we’ll do in this review.

About Great Blue Slot

Great Blue is an ocean-themed slot game that’s fun to play and comes with a max payout of 10,000x – which is actually quite good. Playtech is the developer of Great Blue, a company that has been around since 1999. They have made a large number of games in the past, focusing on stability and trust.


This slot has a high volatility rating, coupled with an RTP of 94.3%. It’s lower than the industry standard, which usually offers a return-to-player rate of at least 96%.

Game Features and Bonuses

Free spins are one of the main features that people aim for in Great Blue. That’s because these spins actually help you get more wins without staking your money every time you hit the spin button. You can get up to eight free spins, depending on how symbols match up on the board.


An important thing to note – when you are able to land these free spins, it’s also going to add a 2x multiplier to the wins you are able to score while you use them. There are also bonus rounds that can actually award you with more free spins – with a maximum of 33.

Game Symbols

In Great Blue, you’re taken into the underwater world, where sea shells, whales, sharks, fish, and several other oceanic elements can be found. The game’s symbols also include numbers and letters (9, 10, J, Q, A, and K). These are the lowest-value symbols. To hit higher multipliers, you’ll have to try and match the wild symbol, which features an Orca, also known as the killer whale.

How to Play

Great Blue is a game by Playtech, and is featured on the Playtech One platform – that means it’s running on a stable system. The game is easy to play and gives you full control not only over your bet size but also the number of lines you’re going to play.


Start by setting the number of lines, and then the bet size per line. You can then press the pink “SPIN” button on the bottom right side of the screen. Next to the spin button, you’ll also see the “Auto Spins” feature – use this if you want the reel to continue spinning automatically a certain number of times.


While the RTP of Great Blue is a bit on the low side, there are some factors that make up for it, such as the 25 paylines and the fact that the slot comes with a jackpot. The game is also made by a company with a well-established reputation and has a great theme for those who love the ocean.
