Great Blue is a Playtech powered online slot that reels you in with a fun
underwater theme and some fantastic opportunities to net some incredible
rewards. Featuring 5 reels and 25 paylines, this game is known for being a high
variance option, so high rollers take note and low rollers are advised to just
keeping swimming.

The animations are rich and crystal clear while the splashing sound effects
adds an atmospheric experience to your game. If you are a fan of online casinos
that take you underwater, then this is the game for you and is available to play
for free and real money.

Great Blue is a 5-reel, 3-row underwater-themed video slot. Powered by the Playtech gaming suite, the high-variance title boasts 25 paylines on which players can look to hit matching combinations. You can expect all the usual casino slot features in Great Blue, only there are a few twists and turns. Playing a free Great Blue Jackpot slot can certainly be fun but it can never be as exciting as when you play for real money. While some of Playtech’s online slot machines are entertaining enough even when played as game demos, the whole point of the Great Blue Jackpot is to chase those exciting cash prizes.

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.
