The aquatic-themed Great Blue is developed by Playtech. The game, which uses a 5×3 layout with 25 paylines, is inspired by life below the ocean and is based on a killer whale named Great Blue. Set under the sea where sunlight streams through, the game takes you on an adventure where you will encounter several sea animals and possibly some serious wins.

On the reels of Great Blue are symbols of aquatic creatures such as seahorses, starfish, turtles, coral reef fish and sharks. Known for being a high-variance game, Great Blue gives away rare but big wins. Let’s take a closer look at this popular Playtech slot.

How To Play

Before setting off your voyage to the bottom of the sea, don’t forget to sign up and deposit at an online casino that offers Great Blue. After that, we recommend you select your paylines and adjust your bets by clicking the ‘+’ and ‘-‘ buttons beside the ‘Lines’ and ‘Line Bet’ selectors respectively. When you’re all set, hit the ‘Spin’ button to start spinning the reels!

If you ever get tired of clicking the ‘Spin’ button, you can enable the auto-spin feature which allows you to select how many times you want the reels spin automatically for your desired number of times. If the reels are not spinning fast enough for you, hit ‘Turbo Mode’ to speed things up.

Special Features

Great Blue

Great Blue the killer whale is the Wild symbol and the seashell acts as the Scatter, triggering the Great Blue Bonus Game. The Great Blue Wild is a Stacked Wild, meaning up to three of them can appear on the same reel, turning the entire reel Wild and helping you land some larger combinations. If the Wild symbol is a part of a winning combination, it will also act as a 2x multiplier.

Great Blue Bonus Game

If players land three or more Seashell Scatter symbols, they trigger the Great Blue Bonus Game in which they are awarded eight bonus spins and a 2x multiplier. Players are also required to choose two of the five seashells where they can win additional bonus spins or multipliers.

In total, players can win 33 bonus spins and up to 15 multipliers. In addition to this, landing three or more Scatter symbols during the bonus spins will award players with another 15 bonus spins too.


Great Blue is a very popular game and it’s easy to see why. The game features some fun bonus features but we wouldn’t recommend it to new slot players. It’s high variance, so don’t expect to win often. When you do win, however, the payouts are big.

You can play Great Blue across a variety of reliable online casinos, including BGO, VideoSlots, Mr Green, Bet365 and PaddyPower Casino. If you are a seasoned gamer looking to win big, have a few spins at Great Blue and it could be a highly rewarding experience.
