Symbols and Paytable

Your success in any slot game is tied to the quality of the symbols you get after every spin of the reels. But you must be conversant with the symbols of the game to know what to expect. In the Great Blue slot game, there are 8 symbols, and they appear as one of a kind, two of a kind, and three of a kind.

The highest paying symbol is the Killer Whale, and it’s closely followed by the Shark and Sea Turtle (two of a kind). Card symbols are the low paying symbols, including A,K (two of a kind), 9, and 10,J,Q (three of a kind).

The special symbols are a Wild and Scatter symbol, which are represented by the Orca, and Sea Shell, respectively. The paytable below shows all the symbols and their values:

Symbols 2x 3x 4x 5x
Orca (Wild) 10x 250x 2,500x 10,000x
Sea Shells (Scatter) 2x 5x 20x 500x
Shark and Sea Turtles (two of a kind). 2x 25x 125x 750x
Seahorse and Starfish 15x 75x 250x
Yellow-striped AngelFish 20x 100x 400x
A,K 10x 50x 150x
9 2x 5x 25x 100x
10,J,Q 5x 25x 100x

RTP & Volatility

After testing the Great Blue slot for a considerable length of time, we discovered that it has medium volatility. We got some nice wins, but not as frequently as with low volatility slots. At the same time, we didn’t have to spin the reels for too long before recording a win, like in high volatility slots. This makes the game perfect for players who love to see sizable wins every now and then. The game’s RTP stands at a solid 96.03%, a rate that’s above the industry’s standard.

Bonus Features

This slot is situated under the deep blue ocean, so you can be sure of many surprises, including bonus features. The adventure starts with a base game and progresses from there. While much may not be happening in the base game, like an online jackpot, the killer whale wild symbol introduces little sparks of excitement every so often.

The Wild symbols appear to double wins and replace other symbols, except the Scatter, to form a winning pattern. However, all these can’t be compared to the bonus feature. Not only is it more fun, the crypto free spins it can deliver are massive. Play Great Blue slot to partake in the action!

Gamble Feature

Landing three or more Scatter symbols will launch the gamble feature, and this bonus round will test your prediction abilities. But before that, you’ll be given a rousing welcome with eight free spins, and 2x multipliers.

In the bonus round proper, you’ll be shown five sea shells for you to pick two that will award you additional multipliers and more free spins. At the end of the bonus feature, you can win up to 33 free spins and 15x multipliers.

Free Spins Feature

During the free spins round, the reels become automated and move on their own, all the while using the previous winning line amount and same multiplier. Extra free spins will be awarded up to 15 of them if 3 or more Scatters appear during the feature. If you’re lucky to keep getting the required number of Scatters, you could win additional free spins indefinitely.
