About Release the Kraken Slot

Brought to our UK online casino collection by big-time developers Pragmatic Play, Release the Kraken plunges players to the sea bed in search of the legendary treasures hoarded by the infamous Kraken including Wilds, Free Spins and more. In true Pragmatic style, their skill and passion for gorgeously designed UK casino games is prevalent in this online slot - the game opens up into the depths of the deep blue where the reels are found buried in the sea bed alongside a sunken ship. There’s a brilliant blue colour palette in use that fits in perfectly with the maritime theme, particularly the mixture of shades used to create the sea that surrounds the reels. If you like online casino slots with a keen eye for detail, Release the Kraken is certainly one to try.

Despite boasting a standard 5x4 reel set this online slot definitely isn’t short of winning potential, offering up between 20 and 40 paylines for players to use in your pursuit of winning paylines, a range of winning Wilds to discover, free spins and wins of up to 10,000x your stake waiting to be discovered beneath the reels.

Among the symbols that adorn the reels are the low-paying A - J live casino card values, whereas heading up the higher-value end of the paytable is a crew of critters such as fish, turtles and sharks. The game's logo is the highest paying symbol, offering a payout of up to 25x for a 5-of-a-kind. The titular Kraken also makes an appearance on the reels as the game’s Wild symbols, which could present players with some potentially valuable winning combinations.
