Great Blue is one of a range of high quality slot games that have been launched by Playtech over recent years. It's a 5 reel and 25 pay line game with slick graphics and an entertaining soundtrack- all based underwater, of course.

Great Blue Slot Game Review

Released by Playtech, Great Blue slot is a 5 reel and 25 paylines Marvel from under the sea, featuring a joyful beachy soundtrack and colourful representatives of marine life as higher value symbols.

With the betting range of $0.10 to $2.50 per line, Great Blue offers a winning potential of 10,000 coins for the combination of 5 Wild icons but carries a slightly lower RTP potential of only 94.3%. Apart from the classic structure of the base game, the slot also introduces a Bonus game triggered by the Scatter symbols, awarding additional sessions of free spins bundled up with different value multipliers.

10,000 Credits Under the Sea

The highest value symbol in Great Blue slot game is the Shark, which is worth 10, 250, 2500 or up to 10,000 coins, depending on the number of symbols that hit the reels. Apart from being the symbol that can generate the highest profit, Shark icon can replace all other symbols (except the Scatter icon), significantly increasing the winning potential by completing any string of icons and doubling the winnings.

The players can manually adjust both the number of the active lines and the betting amount – setting up the coin value at $0.25 and activating the maximum number of paylines can be done either by clicking on the Bet Per Line tab or through the Max Bet button. This will reset the number of active lines and set the stakes to the highest possible amount.

The Auto spin feature is also available, allowing the player to select the number of auto spins (up to 99) and set them in spinning motion that will last until the session ends or until the player manually interrupts it by hitting the Auto Start/Stop button.

Information about the slot icons or paylines can be accessed at any time through the Info tab. The player can then obtain further details about the coin value of each symbol or get additional details on the slot’s Bonus offer.

Great Blue Slot Machine Features

With at least three Scatter symbols (Pink Sea Shell with a pearl), Great Blue slot Bonus will be unlocked, transferring the player to the new screen with 5 different shells, each with a multiplier and a different number of Free Spins.

As soon as the Scatter symbols land onto the reels, 8 Free Spins will be automatically awarded to the player, together with the x2 multiplier. A new set of spins and additional multipliers are then added after the player selects two out of five shells which can contain the maximum of 33 bonus rounds as well as 15x multiplier.

For those of you who enjoy the adrenaline rush and a bit of risk here and there, Great Blue slot machine presents its players with the opportunity to increase both the excitement and the overall balance by using the Gamble Feature option and going for double or nothing.

Upon entering the Gamble game screen, the player unlocks a guessing game with the objective of correctly predicting the colour of the card facing down. Every successful guess will double the selected betting amount and the player can end the game and return to the main screen by simply collecting the amount won up to that moment.

From Microgaming's Mermaid Millions to Ariana from the same developer, underwater-themed slot games have always proved popular with gamblers. It's a top theme for online casino software developers: it lends itself to luscious graphics, the animation can be decent, and the bonus games original.

One of the timeless additions to the genre is Playtech's Great Blue video slot. It's a cracking 5-reel online slot that features Stacked Wild symbols, a free spins bonus with multipliers, and lots of regular icons. In fact, after a couple of minutes surveying the paytable, one can see this is virtually identical to Playtech's Irish Luck slot. But does it deliver four-leaf clovers or a pot of rubbish at the end of the underwater rainbow? Let's find out.

Bet On Paylines For A Top 1500x Payout

Although it's looking a little rusty now, Great Blue still has some signs of (undersea) life. The game is played over five reels and three rows for a 25-payline set-up. Line bets can be set from 0.01 to 2.00 for a max bet of 50.00 per spin. There are also Auto Spins and Turbo Mode functions.

The reels spin fairly well for an older slot, but the animation when you hit a winning payline is passable, especially if a Wild is involved.

Swim Past The Letters And On To The Creatures

The low limit pays for punters are the 9-through-Ace symbols. You'll only need two 9s to earn a 2x-line bet win, but 5OAK (5 of a kind) gets you 100x. Only the A and K really pay better, with 150x achievable for 5OAK.

Keep an eye out for the yellow angel fish. This cutie will pay 400x for 5OAK, with the seahorse and starfish both paying 250x for the same winning payline. The shark and turtle are the best regular symbols and award for just two matching on the reels. You'll earn 2x for two of a kind, but a maximum 750x award for 5OAK is very good. Overall, though, this slot is fairly low-medium volatility given the types of wins we regularly racked up.

Sea Shells Scatters Secure Free Spins On the Shore

The killer whale is this online slot's Wild symbol. Just two Wilds will get you a 10x win, but five Wilds will bag you 10000x. These Orcas will substitute all regular symbols in the game other than the Scatter bonus symbols. In addition, they double any wins they help complete (with the relevant payouts helpfully displayed in the paytable).

The Scatter symbol here is the oyster shell, baring its gleaming pearl for all to see. Just two Scatters gets you 2x, but five Scatters bags the gamblers a 500x prize. In addition, three or more Scatters anywhere will activate a free spins bonus game. You win up to 33 free spins with a multiplier of 1x-15x.

Best Slot Machines To Play

Like Irish Luck, you first have to choose from the clams/oysters on-screen. Each will contain extra free spins or a random multiplier to add to your haul. You begin the round with 8 free spins and a 2x multiplier anyway, so these are welcome additions. Like all the best Playtech bonus slots online, the free spins feature can be retriggered indefinitely.

Head To Ireland For More Of The Same

Great Blue can result in 'great' real cash hauls for punters, especially if you land stacked Wilds on Reel 1. We managed this 2 or 3 times out of our first 100 or so spins for a 10-11x total stake win.

But in most respects, this game is a virtual clone of Playtech's own Irish Luck. That online slot has a similar payout structure to this, as well as stacked Wild symbols and a free spins bonus with a 'Pick 'em' pre-bonus game to play first. It's hard to trigger as well, so in reality you're concentrating on making those Wilds pay as best you can.

Great Blue has some big periods of volatility, especially if you don't a Wild Orca, but land the big underwater beast and you're looking at decent 2-4x total bet wins. Play for free today and see if the variance is on your side. Then take the plunge with a bankroll and play for real money.
