Overview of the Great Blue Slot Game
The Great Blue slot game was developed by Playtech in 2013 and is pretty popular with players. The game sports a respectable 96.03% RTP and has medium to high volatility. That means payouts are a bit far in between but tend to be big.
The game has 3 rows, 5 reels, and 25 ways to win. The minimum bet size is $0.01 when you have only one payline active and $0.25 when all 25 are switched on. The maximum bets range between $2 and $50. With a 10,000x maximum payout, you can win a massive $500,000 here.
Away from the jackpot, players can still get payouts from the standard winning combinations. The game features an underwater theme, so you have symbols like seahorses, turtles, yellow fish, and whales. Five seahorses on a payline pay 250x your bet, while 5 sharks or turtles pay 750x. Any winning combination pays double if the whale Wild symbol is also present.
The seashell Scatter symbol pays when two or more appear anywhere on the screen. Get three or more, and you activate a bonus round where you choose two oyster shells from five, with the chance to win multipliers and free spins.
Great Blue also has a Gamble feature that you can trigger with a winning combination. Here, you’re presented with two playing cards with their faces down. You must then choose which one is red or black to double your payout with a correct prediction. You can keep choosing red and black in the Gamble feature screen to keep doubling or losing an amount similar to your last win.
After playing the Great Blue slot for a while, we can say it has some pretty long losing streaks. When you hit, you usually hit big, though.

How to Play Great Blue at Online Casinos in Malaysia
The Great Blue slot game is quite easy to play, but newbies may need to familiarize themselves with the controls for free before putting in real money.
Where to Bet
Playtech is a leading, award-winning software provider, so you’ll find its games at pretty much any noteworthy online casino in Malaysia. BK8 is one of the best casinos to play the Great Blue slot demo or real money game. You get a generous 288% welcome bonus of up to MYR 2,880 to kick off the game on a high note.
Setting the Coin Value
After the info button, the “+” and “-“ buttons on the bottom-left side of the screen allow you to change the number of lines from 1 to 25. The next set of “+” and “-“ buttons change the bet amount per line. So, if you choose $0.01 on one line, that’s your bet amount per spin. 25 lines with the same amount are equal to $0.25 per spin.
Spinning the Reels
The bright pink SPIN button gets the reels spinning. You can also use the Auto Spin button to play between 10 and 99 rounds. You can set the game to automatically spin until you get the bonus game if you prefer.
Triggering Bonus Round
The bonus round is triggered when you get three or more seashell scatters. You choose two from five shells to get a random number of free spins and multipliers.
Activating the Gamble Feature
Like the bonus round, the Gamble feature is randomly triggered with a winning combination. You get two cards and must predict which one is red or black. A correct guess doubles your payout, while a wrong one loses your original win.
Great Blue Slot Gameplay
For a 2013 video slot, Great Blue has some really good features. Here’s what you need to know.
RTP & Volatility
The Great Blue slot has an RTP of 96.03%, meaning that for every $100 played, the game pays out $96.03. Of course, this doesn’t play out in individual sessions but for thousands of players over time. Some players lose big, while others hit the max payout. Overall, it’s good playing a game with a decent RTP like this.
Theme
Prepare to dive into the deep blue depths of the sea and discover coral reefs teeming with colorful sea creatures, from playful dolphins to majestic whales. Deep Blue features hidden treasures and ancient artifacts scattered across the ocean floor, guided by shimmering mermaids. The symbols here tell their own story. Sharks, turtles, seahorses, starfish, and seashells all support the undersea theme.
Software
Playtech is the brains behind the Great Blue slot. Established in 1999, the company is listed on the London Stock Exchange. Playtech has won pretty much every award, from EGR and SBC to GIA and ICE. You can only expect the very best from such an industry leader.
Zoning in on Great Blue, Playtech tempered down the graphics to ensure the game runs smoothly, even on the least capable devices. The mobile compatibility is a bit limited, though, and we found that you can’t play unless you flip your phone to landscape mode.
Graphics & Sound
The graphics here lean towards a cartoon style, with a swaying kelp forest and bubbles rising to the surface in the background. We didn’t feel the need to switch off the sound like we usually do with other slot games. Deep Blue has soothing ocean sounds, gentle waves, and distant whale songs. Reel spins are accompanied by subtle clicks and chimes, while winning combinations trigger cheerful, melodic tunes and bubbling sound effects.
Understanding the Great Blue Game’s Paytable
Compared to the standard slot game, Great Blue has a decent number of symbols. But because most are sea creatures, it’s easy to confuse one for the other. Here’s what the different symbols pay. It’s important to note that the presence of a Wild, with any combination, doubles the payout.
| Symbol | 2 Symbols | 3 Symbols | 4 Symbols | 5 Symbols |
| 9 | 2 | 5 | 25 | 100 |
| 10, J, Q | 5 | 25 | 100 | |
| A, K | 10 | 100 | 150 | |
| Seahorse, Starfish | 15 | 75 | 250 | |
| Angel Fish | 20 | 100 | 400 | |
| Shark, Turtle | 2 | 25 | 125 | 750 |
| Seashell (Scatter) | 2 | 5 | 20 | 500 |
| Whale (Wild) | 10 | 250 | 2,500 | 10,000 |
Free Spins & Bonus Rounds to Know About
You activate the sea shells bonus feature when you get three or more shells on the screen. Then, “Click to Start Now” to get into the bonus game.
The game presents five seashells, and you must pick two. One determines the number of free spins you get, and the other determines the multiplier. Click “Continue,” and the game will run until you get a total win based on what each spin won.
Play the Great Blue Slot Demo
You can take our word for it – this is a really fun game to play. But if we’re being honest, some of the bonus features take a while to trigger. The symbols and paylines take a bit of getting used to as well. That’s why it’s a good idea to play the Great Blue free slot game in demo mode first.
You can get familiar with the game without spending any money. If you want to see the sea shells bonus feature, for example, you can just set the Auto Spins to “Until Feature” and let it run. This could potentially be an expensive experiment if you were to use real money. The Great Blue free slot also allows you to tinker around with the number of paylines and bet per payline settings until you find your sweet spot.
Maximize Your Great Blue Gameplay with These Tips
Of course, there’s no surefire way to win while playing the Great Blue slot. However, there are a few not-so-obvious things that will undoubtedly help you play better.
- Set a Budget – It’s easy to get sucked into the blue depths of the sea and spend more than you’d planned, so set a budget before you start playing. Decide how much you’re willing to spend and stick to it.
- Choose Your Paylines Wisely – Select the number of paylines that suit your budget and playing style. Playing with fewer paylines can help you manage your bankroll, but it also means lower winning chances.
- Adjust Your Coin Size – Adjust your coin size according to your budget and the desired level of risk. Playing with smaller coin sizes can help you play for longer, but you get smaller wins, even with big multipliers.
- Understand the Free Spins Bonus Feature – The free spins bonus feature is randomly triggered, allowing you to win without spending extra. Make the most of this feature by understanding how it works, especially while playing in demo mode.
- Use the Gamble Feature Wisely – The Gamble feature is randomly triggered, allowing you to potentially double your winnings. Use this feature wisely, as it can also result in losing everything.
How to Play Great Blue on Mobile
The Great Blue slot is perfectly optimized for mobile devices. It’s lightweight, and despite its compact size, the game’s visuals and sound effects remain engaging. Whether you’re playing on a smartphone or tablet, you’ll enjoy the same thrilling gameplay as on a desktop.
To ensure a seamless gaming experience, the Great Blue slot can only be played in landscape mode on mobile devices. The controls are laid out exactly as on the desktop version, making it easy to navigate and play on either device. You’ll have no trouble adjusting your bets, spinning the reels, or accessing the game’s other features.
Great Rewards with the Great Blue Slot
The Great Blue slot may be from 2013, but Playtech developed it with enough staying power to still be fun and popular over a decade later. The cartoon-style underwater theme makes it both lightweight and visually appealing.
The medium-to-high volatility, respectable 96.03% RTP, and massive 10,000x maximum payout make Great Blue perfect for players seeking thrilling gameplay and significant wins. While it may have some dry spells, the game’s exciting features, including the free spins bonus round and Gamble feature, make it well worth playing.
