The Betting

This is not a progressive game so there is no need to play the game on a max bet to get the full-featured version and the maximum jackpot of 10,000 coins. The smallest coin value in the game is 0.1 ranging up to a maximum of 5.00. The minimum amount of coins per line is one going up to the maximum of ten. This makes the minimum bet 0.01 and the maximum bet 1250 coins. This fantastic Playtech video slot will suit a wide range of players but is particularly well suited to players who enjoy a medium to low volatility slot with small and steady payouts.

Animation And Graphics

Great Blue is a fun non-realistic (in a good way) type of video slot that offers fun character icons and a cool underwater background that is subtly animated. The soundtrack is the perfect accompaniment of underwater sounds and cool fun music. While the graphics may not blow everyone out of the water, we think they suit the game perfectly and are a lot of fun.

The Payout Rate

Slots Return to Player (RTP) is a very important aspect of the game and it tells you what you can realistically expect to get out of the game, the higher the RTP percentage the better. In the case of Great Blue, the return to the player is 94.3% which is a bit on the low side. This is not necessarily a bad thing as the game is also a frequent payer and will best suit players looking for a fun game that is also a nice little earner.

  • The most important information about Great Blue:
  •  A very good looking Video Slot
  •  A bit low Payout Rate of 94.3%
  • Free spins allow you to win money without a risk involved

Impressive Graphics and Gameplay

While Great Blue is not the best-looking video slot that Playtech has ever produced and the Return to Player rate is quite a bit lower than most other video slots in the same class, we still think that Great Blue is a lot of fun and certainly worth a few spins at one of our recommended casinos. The gameplay is quite simple and there are some great opportunities to walk away (or swim away) with some nice chunks of underwater treasure! The game also features a great gamble mode for that extra bit of fun and excitement. The gamble feature is simple and all you have to do is choose between red and black, get it right and double your money, get it wrong and lose it all! This game is fun and will appeal to fans of the more classic sort of video slots look as well as fans of underwater themes.
