Release the Kraken slot game
Release the Kraken is an online slot featuring high-paying symbols, reel-infecting wilds, 3x4 wilds, and base-game multipliers. It also has 2 bonus games: one awards random cash prizes, while the other can grant up to 12 free spins, with possible x10 multipliers and 10 sticky wilds.
Theme and Storyline
Release the Kraken is a colourful underwater slot set in a tropical ocean, beside a sunken ship pulled beneath the waves by the Kraken itself.
Graphics, Sound, and Animation
The bright marine symbols include smiling sharks and grinning tropical fish swimming across the reels. The scenery is just as vivid, with bubbles rising through the water and underwater plants swaying in the current. Before a spin even begins, lively artwork and gentle animation hint at a game full of action, visual movement, and sound effects.

Gameplay
Release the Kraken uses a 5x4 reel layout with 20 paylines. During the free spins bonus, another 20 paylines are added, bringing the total to 40 and offering more ways to form winning combinations.
There are 10 regular symbols that can form winning combinations. The highest-value symbols are the Release the Kraken logo and the wild, and both can pay 500x, 200x, or 50x the ‘bet per line’. The other 8 regular symbols are the grinning shark, sea turtle, blue tropical fish, yellow tropical fish, A, K, Q, and J. Any symbol can be substituted by the ‘bubble wild symbol’ or one of 3 randomly triggered wild features.
Select the ‘i’ button to open the paytable and see each symbol’s payouts. To calculate your ‘bets per line’, multiply the ‘coin value’ by the number of coins wagered, then divide that total by the win amount shown in the paytable.
The reels also have 3 scatter symbols: ‘Bonus’, ‘Free Spins’, and ‘Chest Bonus’. Their features are described below.
Bonuses and free spins
Random Spins Feature: At a random point, you may be invited to choose between 3 tentacles.
- Kraken Locking Wilds: The reels continue spinning while 1 of 3 chests is selected at random. The chosen chest awards one of these outcomes: extra wilds on the reels, continued spinning, or a x2 multiplier.
- Colossal Kraken Wilds: When the reels stop, a Kraken wild symbol measuring 3x4 lands across the reels.
- Infectious Kraken Wilds: 1 or more Kraken wild symbols land on the reels and spread to adjacent positions, potentially filling the reels with wilds.
Sunken Treasure Bonus: Land the ‘Bonus’ symbol on reels 1 and 3, followed by the ‘Chest Bonus’ on reel 5, to trigger this feature. A ‘pick me’ game then displays 3 treasure chests; choose one to receive a random cash prize.
Roaming Kraken Free Spins: Land the ‘Free Spins’ symbol on reels 1 and 3, followed by the ‘Chest Bonus’ on reel 5, to trigger this feature. Before the free spins begin, keep choosing chests until one reveals ‘collect’; the free-spins round then starts.
Each chest contains 1, 2, or 3 free spins, so revealing more chests before ‘collect’ appears awards more spins. The maximum is 12 free spins. This round uses 40 paylines and starts with a x1 multiplier, which increases by x1 each time a wild lands. The maximum multiplier is x10.
Wild symbols also stick to the reels and move to a new position after every free spin. You could have up to 10 wilds and x10 multipliers active at once.
Bet sizes, RTP and volatility
Adjust your wager using ‘Coins’, ‘Coin Value’, or ‘Total Bet’. The ‘Total Bet’ box allows a minimum of 0.20 and a maximum of 100.00 per spin. Over time, the stated RTP means 96.5% of bets are expected to be returned. Pragmatic Play rates Release the Kraken’s volatility at 4/5, placing it in the medium/high variance game category.
Conclusion
Players who enjoy action-packed slots and the possibility of larger wins may find plenty to explore in Release the Kraken. The base game includes 3 random wild features and 2 bonus games. Free spins are the main feature for pursuing bigger wins, combining sticky wilds, multipliers, and 40 paylines.
