Where to Play Release the Kraken
Release the Kraken RTP and Wagering
Release the Kraken uses 5 reels, 4 rows, and 20 paylines during the base game. You can wager from £0.20 to £100 per spin.
As with other highly volatile slot games, Release the Kraken spreads its payouts further apart than you may expect if you tend to play lower-volatility games. However, those wins can be big, with up to 10,000x your bet available. You have the best chance of winning this top prize in the Roaming Kraken Free Spins feature, which includes an increasing multiplier and double the paylines of the base game.
To win a cash prize in Release the Kraken, land three or more matching symbols on any payline. The game has a Return to Player (RTP) rate of 96.50%, which is 50% more than the average RTP for a slot.
Release the Kraken Symbols and Audio & Video Design
Release the Kraken is set deep underwater, where a ship lies on the seabed and multicoloured corals sway. The graphics are detailed and fantastic, with lots of detail. Mysterious music plays between spins, and it becomes more dramatic and exciting when you start playing.
There are nine standard paying symbols, one Wild, and three bonus symbols. The Release the Kraken Logo and Wild symbols are the most valuable. The Wild substitutes for all symbols except the Bonus, Free Spins, and Chest Bonus symbols. It can land on all reels, too.

Release the Kraken Bonus Features
Release the Kraken includes three Random Spin features, the Sunken Treasure Bonus, and the Roaming Kraken Free Spins. Let’s find out how they work.
Random Spin Features
During any spin in the base game, you may randomly be presented with a choice of three tentacles. Pick one to trigger one of three random features: Kraken Locking Wilds, Colossal Kraken Wilds, and Infectious Kraken Wilds.
Sunken Treasure Bonus
Land a Bonus symbol on reels 1 and 3 with a Chest Bonus symbol on reel 5 to trigger this feature. Pick one of three treasure chests to win a random cash prize. If you keep finding cash prizes, you can pick again and again. But the feature ends if you find Collect in a chest instead.
Roaming Kraken Free Spins
To trigger this feature, land a Bonus symbol on reels 1 and 3 with a Free Spins symbol on reel 5. You can win up to 12 free spins with 40 active paylines. The feature begins with a 1x win multiplier in effect, and this increases by 1x for each Wild symbol that lands. The maximum win multiplier available is 10x.
All Wilds that land during the feature stay on the reels but randomly move to another position on each spin. You can’t retrigger this feature.
Release the Kraken Final Thoughts
Release the Kraken is a high-volatility slot with a vibrant animal theme, an exciting setting, and five bonus features to discover.
It has a solid RTP of 96.50% and awards cash prizes of up to 10,000x your bet. The three Random Spin features are a great addition and offer you more opportunities to win during the base game. The Sunken Treasure Bonus can lead to win after win, while the Roaming Kraken Free Spins boasts Sticky Wilds and an increasing win multiplier.
