Great Blue Slot symbols and payouts

This slot has 25 paylines over five reels and three rows. Winning combinations pay from left to right, except for scatters, which will pay out in any combination.

In between the bubbles floating to the surface, you’ll see fish, starfish, seashells, and seahorses. There are also classic card symbols.

The orca whale is the highest paying symbol, and the card symbols 9, 10, J, and Q are the lowest paying. 


The symbols pay according to how many you land on the reels. Five orca whales pay the jackpot of 10,000 x your stake, while three will pay 250 x the original bet. 

Great Blue min / max bets

The game allows you to set your bet values. Minimum coin sizes start at 0.1c, and the maximum is $5.

You’re allowed to bet up to ten coins per line. 

Great Blue RTP, volatility & hit frequency

As a high volatility slot, you can win big with Great Blue Slot. The RTP is an average of 96.03%, as with most of the games by this provider. 

Great Blue Jackpot and/or maximum win

Even though this game doesn’t have a progressive jackpot, the maximum win is worth it at 10,000 x your stake.

If you play with the maximum bet levels, it means you can potentially win $50,000! 

Great Blue Features

If the possibility of a big jackpot doesn’t entice you enough, you can also play the gamble feature to potentially double your winnings, and the scatters unlock free spins. 

Wilds, Respins, and other base game features

You can win when you land two or more orca whales, which serves as the wild in both the base and bonus games. 


The wild orca can replace any symbols in the game, except for the scatter. It increases the winnings of any combinations, and five of these are, of course, the jackpot. 

Great Blue Free Spins

You should also keep your eye out for the oyster, which serves as the scatter and can appear anywhere on the reels. 

Bonus game

When you land two or more oyster scatters, you unlock the bonus game. You’ll automatically start with at least eight free spins.

Great Blue special features

Whenever you have a winning combination, you can choose to use the gamble feature to double your winnings.

You have to predict the color of the next card that the game draws, and if your prediction is correct, you increase your win. 

Graphics & Sound

Even though it’s a high volatility slot, the graphics and sound take you to the tranquillity of the underwater world.

While it’s well-designed, Playtech didn’t spend too much time on the animations. Regardless, the theme creates a sense of calm that you’ll expect from an ocean escape. 

Other slots to play if you like Great Blue slot

If you enjoy the Great Blue Slot, you’ll also like Great Blue Jackpot. It’s essentially a clone of this game, except that you can now win four progressive jackpots.

It offers the same tranquil theme, with bigger winnings. 

Another Playtech favorite is Dolphin Reef, similar to Great Blue in both the graphics and gameplay. You’ll also get free spins and a gamble feature with this slot. 

A more cartoon-style version of the ocean-themed slot is Amatic’s Wild Shark. This is another game that will allow you to gamble with your winnings, and that offers free spins.

Yggdrasil’s Reef Run is a fun combination of the one-armed bandit meeting the ocean. The game has 20 paylines and offers free spins. 


Great Blue offers you fun in a calming setting, with the chance to win a substantial jackpot. The game isn’t overloaded with various features but has enough to keep you entertained.

The slot is well-designed and has a fitting soundtrack. Even though it’s a high volatility slot, it offers both low betters and risk-takers the chance to win the jackpot.

If you feel ready to take a break from everyday life, take a spin on Great Blue Slot.
