Despite being a few years old, the Great Blue slot machine has remained top of the pile at a number of online casinos including Eurogrand and William Hill Casino. This is the sign of a truly high quality game, and when you download Great Blue slot you will see that it carries many of the most popular features like free spins, a bonus game and a big jackpot prize that have kept it so well loved for so long.
1. About Great Blue
Based around a colourful underwater theme, Great Blue has 5 reels and 25 paylines to wager on. With the symbols all fishy-related, you will be spinning Turtles, Sharks, Fish, Seahorses and Starfish as well as the 10, J. K, Q, K and A icons. Each will reward players when at least 3 land on one of the paylines, with the ratio of wins boosted by the appearance of the Killer Whale Wild symbol. This symbol can appear stacked on the reels for even more wins, and whenever it helps to make up a winning combination, the value of the prize is doubled.
A Clamshell symbol works as the Scatter, and each time 2 or more come to rest on the reels after a spin, a Scatter prize is paid out, with bigger prizes should more than 2 appear. This symbol also starts off a free spins round when at least 3 are showing.
Players are given a guaranteed 8 free spins, with all prizes doubled in value, but this can be significantly boosted before they begin when the player selects 2 of the 5 clamshells that they are presented with. These award additional spins and a multiplier value, with up to 33 games at a 15x multiplier amount possible.
During the free spins, getting the Scatter symbol again in 3 spots at once will re-trigger an additional round once the current one ends.
If all these features are not enough to interest you in trying out the Great Blue slot game, then how about the Gamble game that can double each win value over and over again. Following a win, click the Gamble option to play, and then decide if a playing card will turn out to be Red or Black. Guessing correctly doubles the win amount and lets you try again, to double up further, while a wrong guess loses the last win and returns you to the base game.
With a jackpot of up to 10,000 coins possible, when the Killer Whale lands right across a payline, Great Blue fully deserves its' popularity which is sure to continue well into the future.
