AboutSlots review of the original + SlotsTemple/Chipy cross-check (Pragmatic Play): default 96.50% with lower 95.50% / 94.50% builds, 5×4 / 40 lines, 10,000x
Configurable RTP — check before you spin. Release the Kraken ships in more than one RTP build (96.50%, 95.50%, 94.50%). Operators can license a lower version, so the 96.50% default is not guaranteed at every casino — verify it in the paytable.

What 96.50% RTP means on Release the Kraken

Release the Kraken carries a published RTP of 96.50%, a theoretical house edge of roughly 3.5% over the long run. Because Pragmatic Play ships this game in multiple RTP builds, that edge only holds where a casino licenses the top version; a lower build quietly raises the edge against you, which is exactly why we flag configurable titles instead of quoting the headline unqualified. As always, RTP is a long-run average over millions of spins, not a per-session promise: the edge is real and permanent, and a high RTP never turns a slot into a reliable source of income.

Volatility, max win & features

Volatility is rated high (4/5). Expect long gaps between meaningful wins, with most of the return concentrated in the bonus — a friendly RTP does not make this a smooth, low-risk grind. The top prize is capped at 10,000x your stake, and the headline features are colossal/kraken locking wilds, infectious (spreading) wilds, random wild base-game feature, free spins with roaming wilds, ante bet.

Our verdict on Release the Kraken

3.7/5
Best for: high-RTP hunters who can absorb variance for a shot at the big multiplier
Skip if: your casino only offers a lower-RTP build of this game

Release the Kraken (the original 2020 Pragmatic Play title, distinct from the 2024 Megaways) is a 5-reel, 40-line slot built almost entirely around an aggressive family of wild mechanics — Colossal Kraken locking wilds, infectious spreading wilds and a random wild base-game feature, culminating in free spins with roaming wilds. Its default 96.50% RTP is a notch above the Pragmatic norm, though operators can serve 95.50% or 94.50% builds, so the paytable should be checked. Volatility is high: returns hinge on the wild features and free-spin round connecting, which makes the base game swingy and the 10,000x ceiling genuinely rare. It suits players who enjoy wild-heavy, feature-anticipation gameplay and can absorb high variance; just make sure you are playing the original on the 96.50% build, not a cut-down version or the separate Megaways edition.
