Great Blue Slot Review

Originality really is the core ideal of Playtech as a brand, which is why its latest effort caught us off guard a little bit. From what we’ve seen Great Blue looks like a dip in quality, as it has a very cheap and cheerful vibe to it.

It has been said a thousand times before, but you can’t simply judge a game on its appearance. So, with that in mind, we have decided to delve a little deeper into Great Blue, but did it prove to be a worthy venture? The following review delivers the ultimate low-down on this brand new Playtech creation!

Amidst the Amphibious Creatures

Much like millions of other players, we have placed Playtech on a pedestal, as the brand’s reputation often precedes any game that they release. Maybe it’s because we expect so much, but Great Blue just doesn’t look like a true Playtech game for us. The theme of the game is based around the deep ocean and all the amphibious creatures found there. Having been done a thousand times before, this theme is tired and Great Blue proves that point. The reels dominate the screen here, with the sea-like backdrop looking notably flat. Great Blue just doesn’t have anything within its theme that excites us.

Boring and drab, the overall appearance of Great Blue hardly improves when you check out what’s on the reels. Fishes, sharks, oysters, and a smattering of the usual low-value symbols make up the numbers here, with a few other creatures thrown into the mix in a failed attempt to liven up the game.

This Shark Smells Blood

Great Blue as a game pretty much plays out like any generic real money slots release. Built around 5 reels and 25 paylines, with there being very little in between that gives the game “zip”. What’s absolutely crazy is that for a game this basic, it’s actually overbearingly difficult at times. With a high variance and a 94.25% RTP, this game is going present a challenge that defies its cheap imagery.

Cost wise, Great Blue has some serious weight, as when you pay in here you’ll certainly have to part with a pretty penny. The minimum cost to cover all lines is 2.50, with the max bet being 25,000.00 a spin. These figures really are no joke, so if you sit down to play Great Blue you best have a bumper bankroll behind you.

Splish, Splash, Splosh

In what is a rare redeeming quality, Great Blue does have a few bonus features that are worth mentioning. As with practically every other Playtech release you have both wilds and scatters to worth with, so free spins can certainly be accessed in this game. That being said, the real fun comes into the equation when you unlock the separate side game.

Coming about when three of more scatters appear on screen, you’ll be charged with selecting oysters, with a set amount of them holding a prize inside. Adding to that, the game does include a gamble mode too, so there are a few little extra titbits here and there to take your fancy.

Bursting the Bubble

If the bonus features of Great Blue lift you up, the controls in this game will bring you crashing back down. Basically, Playtech, as a means to avoiding implementing a second screen, have pretty much crammed every single button into a panel below the reels. Looking forced and playing in a similar fashion, it’s safe to describe the controls of Great Blue as clunky.

Great Blue Isn’t All That Great!

Great Blue isn’t a great game; we simply can’t paint it as anything else. The theme is boring, the game looks pasted together, the controls are clunky, and the gameplay is uninspiring, these issues alone weigh down Great Blue. Yes, the bonus features here are enjoyable and they do improve the experience of Great Blue slightly, but in our opinion it just doesn’t do enough.

As a game, Great Blue probably did have potential at one point, but those days are long gone, so unless you are willing to way through the rest of the game just to get to the bonus features, we’d probably recommend sidestepping this title.
