Great Blue Slot Review

Great Blue Slot RTP, Details & Wager Limits

The Great Blue slot is a rather basic title. The action plays out on a classic 5 reel, 3 row machine that offers 25 paylines. To form a winning combination, land 3, 4 or 5 matching symbols or wilds on a payline, starting from the leftmost reel. For the higher and lowest value symbols, you’ll only need 2 symbols to create a winner.

Use the + and – buttons in the Line Bet tab to adjust your stake. You can see the total bet value below the reels. Total stake sizes start at 25p per spin, rising to a maximum of £50 per spin.

In some territories, the Auto Spins button allows you to run up to 99 autospins if required. Alternatively, leave them running until you trigger the feature round. I’ve had some lengthy waits between feature triggers so keep an eye on things here.

The Great Blue RTP is 96.03% which is about average. This is a volatile slot and is the reason why it’s a very popular game. It has the payouts to match as the maximum win is 20,000 x your total stake per spin.

Theme – head under the sea

As you’d expect from a slot called Great Blue, blue dominates the design here. Based on the blue whale, the setting is a bubbling, underwater backdrop as you head underwater.

Graphically, it’s rather dated but don’t let this take away from the gameplay. The imagery here is very simply done. Likewise, the repetitive soundtrack. There are few design flourishes here but it all works well enough.

The reels in this Great Blue slot game are made up of lower value A to 9 symbols (in blue, naturally). They’re joined by a collection of symbols based on aquatic life. These are far brighter and more colourful and stand out nicely against the ocean background.

You’ll see seahorses, starfish, a yellow fish, a turtle and a shark. The turtle and shark symbols pay the most with 5 in combination paying 30 x your total stake.

The blue whale symbol is the wild. This substitutes for all symbols except the scatter. In its own right, it pays 0.4, 10, 100 or 400 x your total stake when 2, 3, 4 or 5 appear across any payline.

Furthermore, the wild doubles all wins when part of a win. For example: and 5 shark symbols on a payline and you’ll win 30 x your total stake. Land 4 sharks and a wild whale and the payout doubles to 60 x stake.

Great Blue Mobile

You can dive into these waters on your smartphone if you wish. The simple design and rather basic gameplay are perfectly suited to playing on a small screen. It’s not particularly flashy but the Great Blue mobile slot is playable enough.

Bonus Features in Great Blue

Playtech has kept things nice and straightforward as far as gameplay goes in Great Blue. There’s only 1 bonus feature but it offers plenty of potential, combining re-triggerable free spins with big multipliers. Landing wins that include a wild whale can really pay dividends too.

Sea Shells Bonus feature

Land 3, 4 or 5 of the sea shell scatter symbol on the same spin to activate the Sea Shells Bonus feature. You’ll receive a payout equal to 5, 20 or 500 x stake before going on to play your free spins. You are guaranteed to land at least 8 free spins with a 2x multiplier. There are chances to add to that initial haul though via a quick pick me round.

You’ll be offered the pick of 5 sea shell symbols. Select 2 of them. These will add extra free spins to your total and/or increase the size of the multiplier that is active throughout the feature.

It’s possible to land up to 33 free spins with multipliers up to 15x. Re-triggers are available too. Landing 3 or more scatters on the same free spin adds another 15 free spins to your tally. The multiplier from the original trigger is in play during the feature. There’s no limit to how many times you can retrigger the free spins.

Great Blue Review Summary – high variance classic

With its gentle soundtrack and simple design, the waters in the Great Blue slot look rather tranquil. Don’t be fooled though as this is a volatile slot. You can expect lengthy spells when your bankroll will sink to the ocean floor. Even triggering the free spins is no guarantee of success..

The Sea Shells Bonus feature is the key to big wins due to the potential multiplier of up to 15x. It can deliver some cracking action though, especially if you get a big multiplier and a few retriggers.

Despite being an old release, it remains 1 of Playtech’s most popular titles. You should also try Age of the Gods and Buffalo Blitz 2 which are their top games.

The gameplay itself is rather simple. In fact, it might be a little too vanilla for some tastes. If you like the aquatic theme, simple features and volatile gameplay, you’ll likely want to dive into the Great Blue waters. We hope you’ve enjoyed our Great Blue review. Good luck with your bets.
