Release the Kraken Slot Review

The grid and the lines

Wins pay along paylines from left to right. The official rules sheet counts 40 paylines, while the studio's short page description mentions a 4x5 layout with 20 lines; we follow the rules sheet for the line count. The wild substitutes for the regular symbols and is present on all reels.

Bonus symbols on reels 1, 3 and 5 are what open the bonus features. The rules text in our source is not clear about the exact combination needed, so we do not state one.

The features beneath the waves

Two named features define the game, and one of them can be skipped to directly.

Why the free spins reward patience

Two effects build at once inside the bonus. The multiplier only ever climbs, so wins late in the round are worth more than early ones. The wilds never leave, so the number of roaming wilds on screen also grows. A round in which wilds arrive early gets both effects working for longer.

The reverse is also true. If few wilds land, the multiplier stays near 1x and the board holds few substitutes, and with no retrigger available there is no second chance within the round.

Return, cost and ceiling

The rules give a theoretical RTP of 96.5%, which is the only version in our catalogue. With a house edge of 3.5%, long-run play costs about $35 per $1,000 wagered.

Expected costs for 100 spins are $0.70 at a $0.20 bet, $3.50 at $1 and $17.50 at $5. The studio publishes no volatility rating or max win for this title in our data. The 100x buy price and a growing multiplier capped at 10x point to a bonus with a wide spread of results.

Sequels and similar catches

Release the Kraken 2 from 2022 keeps the 96.5% RTP and lists a 5,000x cap. Release the Kraken Megaways from 2024 lists 96.4% with a 10,000x cap.

From the same year, Mysterious Egypt and John Hunter and the book of Tut share the 96.5% RTP, the first of them rated High. Day of Dead from 2021 lists 96.49% with a 4,500x ceiling, and Wild Booster lists 96.47% with 5,000x.

Who should dive in

The game suits players who like features with visible progress: a multiplier counter that only goes up, and a chest sequence where each pick decides whether the reels carry on. Random features on any spin add some variety to the base game. Anyone weighing the 100x buy should remember that it purchases a single, non-retriggering round whose outcome depends heavily on how early the wilds arrive.
