Release the Kraken Review
Release the Kraken is a visually appealing, cartoonish game themed around the legend of the monstrous sea creature that terrorized sailors in the 19th century. Despite its lighthearted appearance, the game possesses a challenging mathematical model.
Do not be deceived by the game's friendly design, as this is a high volatility slot. It features 5 reels, 4 rows, and 20 paylines, with betting options ranging from 20p to £100 per spin across all platforms and devices.
The base game includes 4 different bonus features, and the free spins feature includes a progressive multiplier and sticky, roaming wilds. While wins up to 10,000 times your stake are possible, the game can also test your patience. The RTP of 96.5% is relatively generous, but dry spells can quickly deplete your bankroll.
What symbols are there?
The wild symbol and the Kraken anchor are equally valuable, being the highest paying symbols. Other symbols include sea creatures and standard royal symbols of lower value. You need 3 to 5 matching symbols on a payline to win. Here is the paytable for Release the Kraken:
- Bubble wild - Pays 25x for 5 on a payline
- Release the Kraken anchor - Pays 25x for 5 on a payline
- Shark - Pays 12.5x for 5 on a payline
- Turtle - Pays 10x for 5 on a payline
- Blue fish - Pays 7.5x for 5 on a payline
- Green/yellow fish - Pays 5x for 5 on a payline
- Royal symbols - Pay either 4x or 2x for 5 on a payline
What are the bonus features?
During the base game, kraken tentacles can appear. Selecting one awards one of the following bonus features for the next spin:
- Kraken Lockin – Open chests to receive more kraken wilds, continue spinning (which does nothing) or a 2x multiplier. The feature ends on a collect symbol.
- Colossal Kraken – A 4x3 sized kraken wild lands, covering 3 full reels for 1 spin if fully visible.
- Infectious Kraken – A kraken wild lands and transforms adjacent symbols into wilds.
The Sunken Treasure Bonus game is triggered by landing a bonus symbol on reels 1 and 3, and a chest symbol on reel 5. Pick from chests to win cash prizes, continuing until you find a collect symbol.
Free spins in Release the Kraken
The Roaming Kraken Free Spins feature is the highlight. Trigger it by landing a bonus symbol on reels 1 and 3, and a free spins symbol on reel 5. Select chests to reveal the number of free spins before hitting the collect symbol. Typically, 10 to 12 spins are awarded, but more are possible.
Each chest awards 1, 2, or 3 spins, and the feature starts when a collect symbol is found. The reel set expands from 20 to 40 ways to win, beginning with a 1x multiplier. The progressive multiplier increases by 1x for each wild landed, and all wilds become sticky and move on each spin.
What is the jackpot (max win)?
There is no jackpot, but the potential doubles to 1,000 times your stake during the bonus round. With the progressive multiplier, the max win potential is 10,000 times your stake. This is significant, allowing wins up to £1 million at the highest stake.
