The Great Blue online slot from Playtech is dedicated to the inhabitants of the underwater depths. The game was released in 2012, but the slot machine is still popular among gamblers due to the simplicity of the rules and rather high payout ratios.
About the slot
The five-reel machine has three rows of symbols. The player can adjust the number of active lines from 1 to 25 and bet on each from 0.01 to 2 credits in the currency of the online casino. Prize chains are counted from left to right from the leftmost reel, and for some symbols, combos of only two identical icons are considered winning! If you play Great Blue for real money in an online casino, the payout is determined by multiplying the line bet by the coefficient for the corresponding combination. The RTP is 96.03%.

In older versions, the device allowed you to start the risk game after each win - you can still download videos with the Gamble function active on the Internet. There is currently no doubling round in the slot.

The slot resemblesDolphin Quest byMicrogaming, as well as popular slots Dolphin's Pearl and Orca from Novomatic. In the latter, just like in the slot fromPlaytech, the most expensive symbol is represented by a killer whale. This icon in the game got the role of wild. The secret of the special symbol is that it acts as a multiplier when it completes the winning combinations - the wild doubles the payout.
Another feature of using the wild in the game, which the developer does not focus on in the rules, is the appearance of a special symbol in stacks 2-3 icons. This increases the chances of winning combos both in the standard game and during the free spins.

Underwater symbols appear as bright spots on the blue reels. The high paying values include the yellow fish, purple starfish, orange seahorse, green turtle, and gray shark icons. Low paying symbols are represented by card values 9, 10, J, Q, K and A.

Classic automaton, but it has everything. The ability to play at any stakes, high odds, multipliers on scatters and wilds. Rarely where there are versions with a risk game, but it's a pity. It happened here that in general the budget was merged into a minus, but it happened that it was brought specifically. I have an average of x200 on this machine. The slot is good, though without a plot and twisted design.
Interesting and a Playtech giving machine. All the secrets in the bonus game, where you can get a lot of free spins at once. The slot is one of those machines that either give or not, so I don’t advise you to sit at it for a long time so as not to drain the budget. If you catch a wave, it's quite possible to win here.
