When it comes to video slot payouts, there’s big and then there’s Great Blue. The five-reel, 25-payline Playtech title is a true monster of the deep with its maximum base game jackpot of 10,000x your line bet, but this figure can be further improved by the free spins feature, which grants additional prize multipliers that can boost your winnings by up to 15x.
Great Blue is actually the name given to the majestic killer whale that acts as the slot’s wild and its most valuable symbol; and he’s joined on the five reels by all kinds of marine life including sharks, turtles, seahorses and starfish. The game features a mainly blue colour palette with the unique symbols providing a splash of colour, while ambient underwater sounds play in the background.
Great Blue offers a fairly basic but incredibly rewarding free spins feature that is triggered whenever three or more sea shells appear anywhere on the reels. Initially this awards a prize of between 5x and 500x your bet amount and eight free spins with a 2x multiplier, but players then get to pick two shells from a selection of five to unveil additional free spins and multipliers. The maximum number of free spins during this feature is 33, while the top multiplier level is 15x, with both factors having an absolutely huge impact on your winnings when you consider all wilds appear as stacked symbols.
Something of a video slot classic, Great Blue doesn’t complicate things with additional rules and features, but instead provides a clean user interface that’s highly intuitive. All buttons are clearly labelled, with players having to click “lines” to adjust the number of active paylines, “bet per line” to change their coin amount from 0.01-0.10 and the coin icon itself to alter how much each coin is worth. When combined, these three variables mean Great Blue is playable from anywhere between £0.25 and £125 per spin, making it a suitable option for players using a wide range of bankrolls.
Having established itself as a hugely popular addition to the Playtech catalogue on its bgo release last year, Great Blue is still making a splash thanks to its huge prizes and simple gameplay. The slot serves up a tidal wave of free spins and multipliers, with the presence of stacked wilds usually resulting in multiple paylines being triggered and winnings that would cause a lesser casino to capsize being paid out.
