Great Blue Slot Machine
Great Blue slot machine from Playtech is the king of the high variance slot machines, boasting an outrageously high maximum win of 150,000x your stake – far higher than any other online slot with the exception of those that offer a progressive jackpot. The game features an underwater theme, with various marine creatures adorning the three-row, five reel layout. Should you not find this theme appealing, there are a number of clone machines available with very similar play mechanics such as Marilyn Monroe, Penguin Vacation, and Irish Luck. With such fantastic winning potential, you should be prepared for most of your sessions on this game to result in a loss. That might sound like a good reason to disregard this slot, but if you persevere with the game you stand a great chance of eventually landing yourself a truly enormous win!

This game is showing its age a little in 2016; the graphics look somewhat dated, the animation is choppy and runs at a very low frame rate, and the sounds are almost laughably simplistic and basic. Whilst Microgaming has chosen to upgrade many of their slots with newer “HD” versions to avoid such criticism, Playtech have instead chosen to create new slots using the same features and paytable. Two such examples are “Funky Fruits Farm” and “Fei Long Zai Tian”, which both pay and play identically to Great Blue, but it really doesn’t matter which of these games you choose to play if you are more concerned with payouts than presentation. This is a 25 pay line game, and it’s recommended that you play all of the lines as you are likely to receive a lower RTP if you do not. This is particularly important with Great Blue because the advertised RTP is already very low for an online slot at just 94.3% – far lower than most Microgaming and NetEnt slots.
Great Blue Slot Machine Features
Big wins are possible even in the base game as a result of the stacked orca wild symbols that appear on every reel in Great Blue slot machine. A single line of these symbols pays out 10,000x your line bet, and it is possible to hit a full screen of these for a 10,000x stake payout even without hitting the bonus mode. The scatters symbols appear on all of the reels and pay out 500x your stake for all five, but such hits are extremely rare – triggering the free spins is extremely difficult in this game, so you might not ever see all five scatters on screen at once even if you play many thousands of spins.
Each time you trigger the bonus mode you are presented with five pearls, from which you are asked to select two to reveal the exact attributes of your free spins feature. You are immediately awarded a 2x a multiplier and eight free spins by default, which can be increased up to a maximum of 33 free spins or a 15x multiplier if you choose the best bonus pearls. Sadly it isn’t possible to be awarded both of these maximum values simultaneously, so you will ideally hope to choose one pearl that conceals a multiplier and one that hides some additional free spins. The best picks will result in 23 free spins at a 10x multiplier, but you might also end up with 8 free spins at 15x multiplier or 33 free spins at 2x multiplier, amongst other possibile combinations. Should you hit three or more scatters during the free spins you will receive an additional 15 spins at the same multiplier. The maximum 150,000x stake jackpot can only be won by hitting a full screen of wilds whilst the 15x multiplier is active. There hasn’t been any reports of a player actually hitting this combination in all of the years since this game was released, but it is definitely possible!
Great Blue might well be one of the greatest online slots ever created, and few gamblers would argue that playing this machine is an enjoyable and exciting experience. It can be a little disappointing waiting so long for the bonus round to trigger if you don’t end up choosing a multiplier from the pearls, but when you do score a few spins with the larger multipliers the rewards can be truly immense. Great Blue is available for real money play at lots of high quality casinos including and we have exclusive welcome bonuses available at all of these casinos.
