The great Blue slot has an exciting feature known as “gamble.” When you win, “gamble” is activated, allowing you to guess the color of the next card to be drawn and win 2X your bet. If you win, you can collect your winnings at any point, but you will be returned to the base game.

The Gamble Feature

How to Win When You Play Great Blue

Winning in the Great Blue slot machine depends on the symbols you land on reels. The two main symbols that give you extra chances of winning are wild and scatter. Specifically, the scatter symbol pays when two or more appear anywhere on the reels. And when 3 or more scatter symbols appear anywhere on reels, a free spin feature will be triggered.

The wild symbol, on the other hand, appears anywhere on the reels and is capable of substituting for all other symbols except the scatter. This results in the creation of a winning line that would not have existed. What is even more exciting is that the new winning line created comes with a multiplier of 2X.

The Top 5 Tips for Playing Playtech’s Great Blue Slot

Great Blue is a game of luck. What this means is that there is no betting strategy that can guarantee you winnings. However, there are some Great Blue slot tips you can apply and increase your chances of winnings. They include:

  • Play with all paylines active – Our first Great Blue slot trick is to take advantage of all of the paylines. This game has 25 paylines, which means you can choose to play with all of them active, however, you are also able to select only a few. When you choose a few playlines, you will win less. But when you play with all paylines active, you could win more. You, however, need to keep in mind that playing with all paylines active will require you to spend more money.
  • Start with the free mode – Most online casinos in Malaysia offer Great Blue slot free play. So, if you are a beginner, you can play in demo mode and learn more about the game rules and other important features.
  • Use the gamble feature – The gamble feature in Great Blue allows you to win 2X your bet when you guess the correct color of the next card to be drawn. This strategy is risky, but it’s worth a try considering that you can double your wins up to the $1000 limit.
  • Play with casino bonuses – Online casinos in Malaysia offer exciting casino bonuses for slot players. To this end, you can claim slot casino bonuses and play Great Blue with free money.
  • Set a budget – As a rule of thumb, you should always gamble what you can afford to lose. It is, therefore, important to set aside the amount you are willing to spend on Great Blue before you start playing.

Great Blue Slot Paytable Explained

The Great Blue online slot machine has 25 paylines and 13 thematic symbols. Symbols are the shapes that appear on the reels of the slot machine. Moreover, each of the symbols represents a value and can either be high-paying or low paying. Paylines, on the other side, refer to a lineup of specific slot symbols on which a win is awarded. These paylines can be vertical, horizontal, or diagonal.

In order to win in Great Blue, you need to land at least two symbols on the reels. Each combination of symbols has a multiplier that determines how much you will be paid. For example, landing 3 scatter symbols with a multiplier of 10X on the reels means that you will win 10X your stake. So, if you stake MYR10, you will win MYR100.

Below is a table showing different Great Blue symbols and their payouts:

Symbol 3 Symbols 4 Symbols 5 Symbols
9 5X 25X 100X
K and A 10X 50X 150X
10, J, and Q 5X 25X 100X
Yellow Fish 20X 100X 400X
Seahorse and Starfish 15X 75X 250X
Turtle and Shark 25X 125X 750X
Pearl 5X 20X 500X
Whale 50X 2500X 10,000X

Great Blue Slot Paylines

One of the most important features you should always consider when choosing a slot to play is the number of paylines. Paylines, in simple terms, refer to the line or pattern on which a payout will be awarded. More paylines mean more chances of winning. Luckily, the slot machine Great Blue has 25 paylines. You can bet on these paylines and be awarded if you land the right winning combinations.

Great Blue Slot Paylines

As a player, you need to note that payouts will only be given on the lines you bet on. For example, if you bet on paylines 5-15, you will only be paid winning combinations that fall on these lines. If the winning combination falls outside these lines, you won’t get anything. So, if you want to boost your chances of winning, it is important you activate all the paylines.

Great Blue Slot Free Spins and Bonus Rounds

The main highlight of the Great Blue online slot machine is the sea shell bonus feature. This bonus is capable of triggering free spins with impressive multipliers. You can trigger this feature by landing 3 or more scatter symbols on the reels. After triggering the feature, you will automatically receive 8 free spins with multipliers of 2X.

Great Blue Slot Free Spins

The slot machine also gives you a chance to pick 2 shells out of 5 before entering the bonus game and trigger additional free spins with multipliers. Specifically, you will get up to 33 free spins with multipliers of 15X. And when you land at least 3 scatter symbols during the free spins, you will get another 15 free spins. There is no limit placed, meaning you can re-trigger as many free spins as you want.

Great Blue Gameplay

The Great Blue online slot machine from Playtech is full of aquatic fun. With a high RTP, exciting bonus features, and multiple paylines, the video slot gives nothing but an opportunity to scoop big wins. Below is a quick rundown of some of the features that make Great Blue a great choice for Malaysian players.

RTP & Volatility

The Great Blue casino game RTP may not be the highest out there, but it is above average. In particular, the slot machine has an RTP of 96.03%. This means that the video slot will payouts 96.03% of the money wagered over time. For instance, if players wager MYR1000 in a given period of time, the game will return MYR960.3 in the form of winnings.

The remaining MYR39.7 is the profit for the operator. Compared to other Playtech slot games, Great Blue has a slightly lower RTP of 96.03%, however, it isn’t that much of a drop when you consider that most of Playtech’s other titles have RTPs that range between 97% -99%.

The slot is also highly volatile. What this means is that the game will offer huge payouts, but less often. If you are a risk taker, this is the perfect slot machine you should give a try. But if you are the type of gambler who runs out of patience quickly, you should consider playing slot machines with low and medium volatility.

Graphics & Sounds

The graphics and sound effects in Great Blue may not compete with the latest Playtech slot machines, but they are well done. The graphics are in HD, making the game more aesthetically pleasing. The graphics also play a big role in theme enhancement, better eyesight, and improved gaming experience.
