Introduction to Great Blue Slot

Great Blue Slot by PlayTech
Great Blue Online Slot by PlayTech

Great Blue Online Slot Malaysia is deigned in standard 5x3 reel grid features a bunch of friendly, aquatic critters in addition to a wild symbol, a free spins bonus, and a gamble bonus. The backdrop is of the deep blue ocean, with bubbles floating upwards towards the surface.

The reels themself are of a different shade of blue to the water in the background, and numbers from 1 to 20 appear on both the left-hand side and right-hand side. You may decide how many lines to play, from 1 to 20.

At the bottom of the page, there are some regular controls. Just like the others normal online slot games, you can select your desired total bet, lines bet and number of auto spins.

Graphics and Theme of Great Blue Slot

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 While some will find the design outdated, there is a certain charm to the old-school feel.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.

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 game 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.

RTP of Great Blue Slot

In Great Blue online slot, the RTP is 96.03%, which means that a player wagering 100 coins could expect to win back 96.03 coins. Of course, this figure doesn’t equate to a single playing session, so it would be foolish to approach this game anticipating this type of win level. Many thousands of playing hours are used to arrive at this figure, so you should use it merely as a guide. Remember that numerous factors govern your overall returns during a gaming session, and it’s possible for one player to suffer heavy losses while another is scooping a major prize.

The high variance factor is partly down to the Wild Multiplier that increases your winnings from combinations that include the killer whale Wild. The bonus feature games also contribute to the high variance, bringing the potential for some huge wins with constantly recurring free spins that could increase your prize pot, sometimes quite dramatically.

Playing a high-variance online slots game means keeping your nerve and being prepared to spend a great deal of time and money on chasing down those big wins. Simply logging on and playing the game a few times with relatively small amounts of cash won’t scoop you any of the big prizes, but players who settle in for the long term and play cautiously but sensibly can reap significant rewards.

It’s Great Blue’s high variance and good RTP that attract keen players time and time again, with many online slot’s fans citing the game as being one of their firm favorites thanks to the opportunity to benefit from significant prize pots over the course of a playing session.

Game Symbols and Paytable of Great Blue Slot

The paytable of Great Blue slot game Malaysia are as shown at the picture above.

The number 9 is the lowest-scoring symbol on the reels, but players can score a win when just two of them appear on consecutive reels, beginning from the leftmost reel. Next come the number 10, the Jack and the Queen symbols, which are the second lowest-scoring symbols, requiring three matching symbols on consecutive reels starting from the leftmost reel to score a win. Close on their heels come the King and Ace symbols.

Bigger wins occur with the cutely-animated aquatic stars of the game, beginning with the gorgeous yellow-striped Angel Fish. Next in line come the starfish and the seahorse, but it’s with the next two symbols, the shark and the turtle, that bigger wins appear on the paytable. With these two characters, as with the Number 9 symbol, a win is achieved by achieving just two matching icons on a winning payline, with one symbol occurring on the leftmost reel and the next on a consecutive reel, making these icons particularly desirable during gameplay.

There are 4 ‘of a kind’ symbols included shark, flatfish, sea turtle, and a starfish, the combination of different symbols will give you different bonuses. These figures have equal payouts. It means you from winning combinations of the two symbols. For instance, if you get three starfish and seahorse icons, you get 15 credits. Five of them boosts your win to 250 credits. When you use a wild symbol to form a winning combination of these icons, you earn 500 credits for five starfish and seahorse symbols.

The highest paying combinations are the shark and sea turtles. Five of them will get you 750 credits. If you use them with a wild, you obtain 1,500 credits. The flat orange fish gives 400 credits if it appears five times on the reels. However, if the wild is present, your win boosts to 800 credits.

Bonus Symbols of Great Blue Slot

The provision of slot bonus features on top of the ordinary character wins is a defining factor in the success of online casino games. The real money and free slots Great Blue do not get left behind in this respect and include several incentives to keep players spinning its reels. These incentives are crafted around the game’s ocean theme, but they are standard boons at their core. These rewards include:

Five orca symbols award the big win of 10,000 times the line bet. Two, three, and four occurrences of the same icon on a line grant 10,250 and 2,500 coins, respectively. These wins are also adjusted according to the line bet.

2 – Scatter

The Scatter is a pink oyster holding a giant pearl. As a special symbol, it cannot be substituted by the orca Wild. The character also awards winnings in any order on the reels without being bound to appearing on active play lines. Two, three, and four Scatters grant two, five, and twenty times the total stake, respectively. Five pink oysters award the maximum payout of 500 times the wager.

Similarly to the wild symbol, scatter symbol also can form clusters of its own when you get 3 or more scattered oysters, we called it Sea Shells bonus. When activated, the feature awards 8 Free Spins with a two-times multiplier applied on all collected winnings. Before the bonus starts, 5 shells are presented, of which 2 have to be selected. The chosen shells reveal additional Free Spins or multipliers. In some instances, both incentives can be awarded.
