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.

Gamble

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.

Summary

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.

LIKED

Great Blue is nice underwater designed video slot from Playtech software. It has 5 reels and 25 paylines. I played it for a few times, at different casinos, different sessions. I don't have any good results at it, I had no big win on it. But I still like to play it, because the potential on big winnings are huge.

This game has good theme and I like to play underwater themed games. In some way it relax me and I think there under the sea could be some treasure too. The game has only one bonus and that is free spins. You can win up to 33 free spins or up to x15 multiplier. When three or more scatter bonus symbols appear you get automatically 8 free spins with x2 multiplier. Later you have to choose two out of five sea shells to win more free spins or multipliers. I like that free spins could also be retriggered with 15 free spins played with the same multiplier as the triggering spin.

So this is really huge potential on winnings. I played it many times, I received free spins only a few times. And after I selected shells, I received more than 20 free spins and around x4 or x5 multiplier. But the payouts during free spins were not so high because I did not have wild symbols. The wilds pay out really huge so if you catch them into free games you are lucky.

Great Blue can easily eat your balance. I know that because it happen to me. I played at minimum bets and after free games I raised the bet. But suddenly my balance falling down, without any wild symbols or free games. I think you need to have a really good bankroll to play this game, or very very lucky day. I will rate it with 9 stars, it is a good game.

DISLIKED

I was in two minds about reviewing this game, as I know if my boyfriend reads this he will scream “SACRILEGE!!” at me at the top of his voice haha. This is one of his all time favorite slot games, and whilst I do like it in a way – I’ve had a few good wins on it - my time playing it has definitely come to an end as I’ve decided it’s basically one of the biggest ripoffs in on-line slots.

The thing about Great Blue and its clones, is that if you look up there RTP percentages on-line, you’ll discover them to be DRASTICALLY below that of many other games. In fact the figure is around 92%, which you may think is not that much less than the 96-98% offered by some other games from say Microgaming or NetEnt, but if your just making a small deposit, this is exactly why you will find it lasts MUCH less time if you drop it into this slot than another game eg Dead or Alive, Frankenstein, Thunderstruck2 or Break Da Bank Again which all have the higher payback percentages.

Another big ripoff about great blue is the scatter frequency – I don’t know the official numbers for this but I’m as certain as I possibly can be that this game enters the bonus round MUCH less frequently than other slot games. I’ve sat and span the reels over 1,000 times without a single feature on multiple occasions, something which only tends to happen on very rare occasions when I play other games. I’ve had even worse results playing the clone game Marilyn Monroe. What can this possibly be all about?!

I guess the fact is, because the feature on this game has such insane payout potential – scoring a full line of wilds in the 15x multiplier mode will pay you out a sickening amount of money – the odds of even entering this mode have to be dropped dramatically, on top of the near impossibility of actually hitting such a combination anyway. I know I’ve never had a line of wilds in this game full stop, even in the base game, and I’ve played it a lot!

Undeniably, this is an addictive game because of its enormous variance and ability to pay you out your whole months salary on a 25p spin should you get lucky. Trouble is, the rest of the time it’ll empty your wallet so quickly you’ll be needing overtime to recover the damage to your bank account! This one is only the brave – or the lucky!
