How to play Great Blue mobile slot

Dive deep into the Great Blue mobile slot ocean as you seek three precious pearls that open up a world of incredible free spins and multipliers.

Some people love, and some people hate underwater-themed slots. A safe choice theme for so many software providers, the Great Blue mobile slot from Playtech doesn’t try and do anything original with what has become a fairly standard theme in video slots.

Diving into a blue underwater world, you’ll find Wild Orca’s that double your win and leap out of the ocean only to sink further to join spinning turtles, bright starfish and inquisitive sharks. Your high cards A – 9 are all represented in bubble format, and whilst it’s not original, the graphics are well done, and the little videos of winning symbols are always entertaining.

So far, all sounds pretty standard. But wait… hidden in these deep sunken shores is a high volatility slot with the chance of a massive payout.

Stacked Wilds with Multipliers

First, the Wilds double all wins and often come stacked, creating big wins during the base game. Sure the hits don’t come often, but often enough that your bankroll, if you are careful, can last a while.

But there is no denying that this slot machine suits the bigger better. Why? Because you’ll need patience to hit what is an incredible free spins bonus feature. Not incredible in terms of slot theme, the Great Blue slot background is simply replaced by a coral reef, but because you can expect to get at least 20x your bet in winnings.

Although the game tells you that you can get from 8 to 33 free spins with a 2x to 15x multiplier, chances are you’ll get one or the other with the min-max of the opposite. So 8 free spins with 15x multiplier, or 15 free spins at 7x or even still 33 free spins with a 2x multiplier.

And if you get a doubling wild symbol on a 15 multiplier, you can get some incredible wins, getting over 40x your total bet.

Great Blue slot will not be for everyone

You’ll need a hefty bankroll and betting 10 to 25 coins a spin to see some real return, especially as this mobile slot has a medium to low return-to-player rate of 94.25%. This will turn off many players who will be disappointed by the small wins that do not cover the spin’s value. That said, this game is really one for the long haul.

Best of all, even though it’s one of Playtech’s least imaginative video slots, it still manages to look and play flawlessly on your mobile or tablet device, making gameplay incredibly easy and allowing you to swipe the reels down to spin.

If you are a fan of the online Great Blue slot machine, remember that there are two noticeable differences to the mobile version. For one, the maximum bet here is £/€/$50 and not £/€/$250, and strangely, they removed the gamble function.

Oh, and just in case you are sitting on the fence, wondering exactly how big you could win on this slot and whether to play, we probably should mention that the max potential win is 500,000 coins.

That should get you down from that fence and diving straight into these hopeful blue free spins waters.

Bonus Features

Stacked Wilds: The Orca is wild doubling all your wins on an active payline and substituting all symbols except scatter. These often and usually come stacked across all the reels.

Free Spins: 3 or more pearls in their shells is the scatter symbol and what will send you to the lighter blue waters of a sandy coral reef and Hawaiian music.

You enter the game with an automatic 8 free spins and 2x multiplier. You first get a set of 5 pink seashells to pick from. Here you'll pick 2 to get anything up to 33 free spins and 15x multiplier. As explained in the main review the number of free spins and multipliers tend to equal out, but the potential for big wins here is huge.

Great Blue Review Conclusion

You'll either love it or hate it, but one cannot deny that the Great Blue mobile slot is one of Playtech's most popular slot games for a reason.

You'll need a little patience to hit it big, but the thrill of chasing those white pearly scatters will keep you entertained if you have the bank roll to do it.

Not the highest return-to-player rate in the world or the most inventive theme, but this slot online game plays beautifully and gives you enough little thrills to keep you waiting for the big win.

A classic that fans of Playtech casinos need to play at least once in their life - perhaps even the online progressive jackpot slot version.
