Release the Kraken Demo & Review

Release the Kraken review

Release the Kraken is a 4x5, 20-line underwater slot with plenty going on in the base game. Random features can trigger on any spin, adding extra action to otherwise ordinary rounds.

The free spins round is built around roaming wilds and a progressive multiplier. Wilds move across the reels during the bonus, and the multiplier increases as the round goes on, so a long feature with active wilds can build towards the advertised 10,000x maximum. The 96.5% RTP is Pragmatic Play's standard top setting. It's an older title, but the mix of random base-game features and a progressive bonus has kept it popular, and it led to two sequels.
