How to Play Great Blue Slot Game

The Great Blue slot game is placed on a 5x3 grid with 25 paylines paying from left to right. It’s a pretty simple game, even if you’re a newcomer to online slots. You must first decide your line bet wager and select how many paylines you want to bet. There are + and - controls which can help you adjust your stake. You can bet on 1-25 paylines, depending on your bankroll. Remember that playing on more paylines increases your chances of landing a winning combination.

Once you set up your wager, you can hit the pink spin button. If you’re impatient to wait for the reels to stop one by one, you can turn on the turbo button to speed up the game. And if you get tired from repeatedly clicking, there is a handy autoplay option on the left of your console with a window showing the number of spins to select from.  The basic information of the game, such as symbols, features and paytable, is clearly visible to players. Just press the info button on the leftmost side of the console and learn everything you need to know about the Great Blue slot game.

Game Symbols and Paytable 

The game symbols are beautifully designed underwater creatures. The cast of characters includes a shark, sea turtle, seahorse, starfish, and angelfish as higher-paying symbols. Lower-paying symbols are underwater air bubbles forming the card numbers 9, 10, J, Q, K, and A. 

How much are they paying? Check below:

• Orca whale (wild) - 2x, 3x, 4x, 5x pays 10; 250; 2,500; 10,000
• Seashell (scatter) - 2x, 3x, 4x, 5x pays 2; 5; 20; 500
• Shark - 2x, 3x, 4x, 5x pays 2; 25; 125; 750
• Sea turtle - 2x, 3x, 4x, 5x pays 2; 25; 125; 750
• Seahorses - 3x, 4x, 5x pays 15; 75; 250
• Starfish - 3x, 4x, 5x pays 15; 75; 250
• Angelfish - 3x, 4x, 5x pays 20; 100; 400
• A, K - 3x, 4x, 5x pays 10; 50; 150
• 9 - 2x, 3x, 4x, 5x pays 2; 5; 25; 100
• 10, J, Q - 3x, 4x, 5x pays 5; 25; 100

As can be seen on the paytable, the lowest paying symbol is 9, but you can win with just two 9 symbols appearing on a payline. The second lowest-paying symbols are 10, J, and Q, and you need to match 3 of them in order to get paid. The higher-paying symbols at the bottom of the list are seahorses and starfish. You will get bigger winning combinations if you hit 5 angelfish on a payline. The most valuable symbols from the regular ones are shark and sea turtle, paying for a minimum of 2 matched symbols on a payline.

The orca whale is our wild symbol here, and it can bring you a grand prix prize worth 10,000x your stake by landing 5 friendly killer whale symbols on the screen. The wild symbol can appear anywhere on the reels and substitute for all symbols except scatters.  A shining pearl in a shell is a scatter symbol and pays much less than a wild, but it can take you into the bonus game round with a maximum of 33 free spins and a 15x multiplier.

Great Blue RTP

The Great Blue slot game has a 96.03% RTP, which is a pretty high percentage. This essentially means that 96.03% of all combined wagers will be paid back to players over a large period of time. It’s a highly volatile slot game, and maybe that’s the reason for its popularity. The high variance of the game mainly comes from the great potential of the bonus round that can bring you a 15x multiplier and a total max win of 10,000x your stake.

Free Spins

The most enjoyable part of the game is entering into a free spins round. Maximum excitement! If you’re lucky enough to hit the 3 scatter symbols on the playfield, you’ll be rewarded with 8 free spins and a 2x multiplier. At the beginning of the round, you can pick 2 of 5 shells that can bring you up to 33 free spins and a 15x multiplier. The same feature can be retriggered in the free spins round, giving you the possibility of great wins with a maximum of 15x multiplier.

Paylines

You can manually modify the paylines of the Great Blue slot, and select to bet on 1 through 25 paylines.  IrishLuck’s experts advise playing with all active paylines to get the maximum from the game. To form a winning combination, you must land 3, 4 or 5 of the same symbols on a payline starting from a leftmost reel. If the wild symbol is included on a payline with other symbols, it doubles your winnings. The cost of a line bet is moving from €0.01 - €2, and while playing on 25 paylines, your total bet ranges from €0.25 - €50.

Highest Payout

The Great Blue slot machine by Playtech is one of the highest-paying games that you can find at online casinos. If you happen to line up 5 orcas on a payline, you will win a massive jackpot of 10,000x your stake. And if you play with €50 per spin? Do the math.

Maximum Bet

The maximum bet of the Great Blue slot game is €50. It doesn’t take a genius to calculate that the maximum payout of the game is €500,000 – considering the 10,000x multiplier you get by landing 5 orcas on a payline.

Minimum Bet

The minimum bet at the Great Blue slot game is only €0.01 if you select only 1 payline. However, it is recommended that you play with at least €0.25 by selecting all the paylines to fully experience the game.
