Great Blue is an aquatic video slot powered by Playtech software provider. This slot has 5 reels and 25 paylines and it focuses on the life under the ocean waves. The name of the slot is drawn on the great blue whale. The bubbly crysta­¬l­-c¬le­a¬r sounds and splashing animations of the game are even reminiscent of some of the finest land-based video slots. Dive deep underwater at any Playtech Casino and spin these reels for real or you can swim with the creatures just for fun by loading the game here on our page.

How to Play Great Blue Slot

As far as online video slots go, Great Blue is simple to play and understand.

  • You can set your bets as you see fit by clicking on Click to Change Coin, Lines and Bet per Line buttons.
  • Spin will get the reels in motion once you choose your betting range.
  • Autostart is essentially the autoplay option and it will spin the reels for a chosen number of times without any interruptions.
  • If you click on Bet Max the bets will get set to the highest possible and the reels will spin automatically at that bet.
  • If you hit the Gamble button after a win, it will trigger the gambling feature.

Slot Features

This slot doesn’t have many features but it does have the essential ones, the Wild and Scatter and one bonus feature.

Great Blue Whale is the Wild symbol in the game and it can substitute for all the symbols in the game except for the Scatter. In addition, all wins where the Wild substitutes will be subjected to x2 multiplier.

Free Games Bonus

Pink Oyster Shell is the Scatter in the game which can form scatter wins. Once you land 3 or more of them anywhere on the reels you will automatically trigger the free spins feature and will be awarded with 8 spins and x2 multiplier. 

At the beginning of the feature you will get to choose 2 out of 5 shells that can award you with additional spins and/or multipliers. You can win up to 33 spins and up to x15 multiplier. Additional 3 Scatters during the feature will retrigger it and award extra spins at a multiplier the same as the triggering spin.


Players who are feeling extremely lucky can even try out Great Blue's gamble feature after a win in the base game. Guess the color of the card next to be drawn and win double your bet! You can collect the wins at any point which will return you back to the base game. Be careful, though. Using the gamble feature too much can eat away at your bankroll in a heartbeat. On the other hand, you can double up your wins till you reach the $1000 limit.


When everything is taken under the consideration, the Great Blue slot is nice looking slot with some neat graphics and sound effects. However, should you decide to hit the reels on this one, thread carefully because this is high variance slot. You can win big but it might cost you money and nerves till you get there.

Great Blue is another old time classic slot, by Playtech. The slot has relaxing layout with blue colour filling up the game. The theme the game has, is about the underwater world. The game has indeed very interesting gameplay and funny bonus sytem. Lets start with the bet. The minimum bet is 0.25 cents, which is a very good bet for players who like to play on minimum bets or just play with low bets. Also the maximum win a player can get in this slot, is capped to 10000x which is great and possible to be achieved if you ask me. Also, another interesting thing about Great Blue Slot is the background music. Its relaxing. From personal experience, I do like slots with soft music background. In the basegame there are not a lot of things to do or see. The aim is to trigger the bonus. Except that, you may get some good wins since the wilds tempt to be stacked. When it comes to the bonus, in order to trigger it you need to bring 3 scatters. Then you will be given 2 picks, in order to choose the free spins amount and the multiplier. Also in the bonus game, you can also retrigger the bonus, which gives you additional 10 free spins. From personal experience, i had quite a few good wins in this game. Its a great game to play with minimum bet or higher. I play it from time to time, hoping to see the stacked wilds coming in the reels with the 10x multiplier. Very nice slot.


The only bad experience I had with Great Blue was the high difficulty of triggering the bonus. Also, since Great Blue is released couple years ago, the graphics it has, look like outdated or very old to say at least.

So hard to win now ?
Even bonuses hard to get?
Sometime even smaller bet can win big.
Better try 10 to 50 spin first.


Slow loading, late bonuses, small bonus win, scatter hard to get rarely come
