Great Blue Casino Slot Game Reviewed

While Great Blue is somewhat simple in its design and gameplay, it is a classic slot that is still enjoyed by many. With 5 reels and 3 rows, it takes little time to get to grips with the rules. Be sure to keep a close eye on the Whale Wild, which doubles all winnings, while a free spins feature and multipliers also help to keep players satisfied. Having tested the slot extensively, we know everything there is to know about Great Blue. So, let’s take a closer look at the Great Blue slot from Playtech, which is readily available to players in Malaysia today.

Great Blue Slot’s Graphics and Themes

The underwater theme of Great Blue is very much part of its appeal. While some will find the design outdated, there is a certain charm to the old-school feel. As you would expect, the colour blue dominates throughout, with the clear water featuring bubbles, reefs and shells. High value symbols include turtles and sharks, with starfish, turtles, sharks, pufferfish and seahorses also featuring.

Great Blue slot

Such symbols bring some much needed colour to the slot, with symbols A-9 being a little bland. Finally, the soundtrack is a little repetitive and tedious, which can be frustrating when playing the Great Blue slot for long periods. All in all, Great Blue is perhaps in need of an upgrade. However, given that the game has been around since 2013, it appears likely that Playtech will stick with the tried and tested graphics and design.

Great Blue Slot Bonus Features

There is just a single bonus feature to speak of with the Great Blue slot. While this may come as a disappointment to some, it does help to keep things simple, which is in keeping with the game as a whole. The available bonus feature does combine both free spins and multipliers, which can be hugely rewarding. Be sure to look out for the Whale Wild, which is also potentially lucrative. Let’s take a closer look at the Sea Shells bonus feature, which is what most players will be on the hunt for.

Landing 3, 4 or 5 sea shell scatters on the same spin will trigger the Sea Shells bonus feature. Here, players will earn a payout worth 5, 20 or 500x your stake. At this point, players will start playing for their free spins. 8 free spins are guaranteed with a 2x multiplier, which can be added to through a quickfire round.

Great Blue bonus round

Players are offered 5 sea shell symbols in total, with two having to be chosen. Doing so will increase both the number of free spins and the size of the multiplier that is active during this bonus round. A maximum of 33 free spins can be won, with multipliers as high as 15x also being available. Finally, landing 3+ scatters on the same free spin will bring about another 15 free spins. There is no limit to the number of times in which free spins can be triggered either!
