The game principle of Great Blue Slot

Great Blue slot game, like most slot machines, is played on 5 reels and 3 rows. In the game with up to 25 paylines, the player gets to deal with all sorts of sea creatures, which are complemented by the common card symbols. The whale acts as a wild in the slot. The whale not only completes the paylines as a wild, but also combines them with a double multiplier. Moreover, it generates the highest paylines by far. The pearl shell as a scatter is particularly attractive.

Here, the game developer has obviously taken Dolphin’s Pearl from Novoline as a model, where a pearl also plays the main role in a sea world. If at least three of the shells with pearls appear on the columns, the free spins begin. In any case, the player gets 8 free spins with a twofold multiplier. However, in a click-me game, the player can drastically change the conditions in his favor. He may click twice on one of the five pearl shells and in return he will randomly receive additional free spins and multipliers added to his base. In the best case, the player can play 33 free spins with a 15x multiplier after the feature. There is no jackpot in this slot. Instead, the player has the opportunity to double his earnings in a card risk. The player can bet on red or black. If he guesses the color of the playing card correctly, then he has doubled his winnings and can repeat the process up to a certain limit. If he bets on the wrong color, the win is lost, the scheme is known. Due to the classic orientation of the slot machine, the spins are swift. The strong graphic charms of the game have a rather subtle effect on the player, creating a stimulating atmosphere for playing.

Stakes, features and winnings

The slot machine Great Blue is not necessarily a slot for high rollers. Thus, the stakes per spin vary from one cent to 12.50 euros. The player can vary the number of paylines from one to 25 when setting his bet.Also, he can decide whether he prefers to play for free or for real money. The payout rate is 94.25 percent, which is still in the average range. The paylines start with the playing cards, which give the game the necessary structure and naturally count the least. Thus, the 9 generates wins of x2, x5, x25 and x100. The 10, Jack and Queen differ from the 9 only in that a deuce chain is not paid. On the other hand, the king and ace pay out considerably more with x10, x50 and x150. This is followed by the seahorse and starfish, which pay the player’s winnings by x15, x75 and x250. The fish already pays x20, x100 and x400, while the shark and the turtle generate winnings of x2, x25, x125 and x750. In a way, the wild symbol takes the cake in this series. If the whale is involved in the paylines, there is a shower of money for the player with x10, x250, x2,500 and x10,000.

Payment method

Online casinos, which offer their players slots like Great Blue, usually also offer a whole range of payment options. Among the most popular ones, besides the credit card, are probably Skrill and bank transfer.


Great Blue is a professionally designed slot, which is fast and pleasant to play and where the player can hope for the warm windfall with some justification. As seen, wilds and scatters have an even higher importance in the game than usual from other slot machines. With many free spins, high multipliers and the paylines of the wild, which are already reminiscent of jackpot wins in a chain of five, the slot player can leave the underwater world with a beaming smile and a lot of money again. Especially the free spins with the high multiplier are worthwhile. The player misses out if he cancels the game before it even enters the free spins.
