Slot Summary

The Kraken is an active meddler in Release the Kraken, Pragmatic Play's underwater slot, interrupting ordinary spins with different wild effects. Treasure-chest choices also shape its bonus sequences. That combination gives the sea monster more to do than decorate the reels, with sudden interventions separating regular play from the longer roaming-wild round.
MechanicsFree-spin wilds persist, relocate and increase the multiplier

How It Plays

Ordinary combinations pay from the leftmost reel across adjacent reels. Wilds replace regular symbols, but they do not stand in for the symbols required to activate either bonus route.

Randomly appearing tentacles introduce a selection during base play. The chosen tentacle reveals a Kraken modifier, temporarily changing how wilds affect the field before the game returns to its regular loop.

Features & Win Potential

Infectious Kraken Wilds convert neighboring symbols into additional wilds. Colossal Kraken Wilds instead place an oversized wild across part of the reel field, changing several positions together for that result.

Kraken Locking Wilds uses successive chest selections while the reels continue spinning. Reveals can add wilds, continue the sequence or collect, with some outcomes also doubling wins before the feature settles.

Bonus & Free Spins

Bonus symbols on reels 1 and 3 plus a Chest Bonus on reel 5 open Sunken Treasure. Select chests to accumulate cash prizes; finding Collect ends the picking sequence and awards the accumulated amount.

A Free Spins symbol on reel 5 with those same initial Bonus symbols opens Roaming Kraken Free Spins. Chest picks determine the spin allocation. During the round, landed wilds remain, change positions between spins and increase the win multiplier.

How long could a bankroll last on Release the Kraken? We simulate thousands of sessions from this game's published RTP and volatility — the long-run math, not a prediction of your next spin.

How this works

Each simulated spin either misses or returns a win drawn from a log-normal distribution, with the hit rate and spread set by the slot's volatility tier (High). The model is calibrated so the average return equals this slot's published RTP (95.50%), with wins capped at its top multiplier (10,000×).

This is a simplified, parametric model of the game's math — not its real paytable. It exists to make the house edge visible over many sessions, so the numbers above are averages across thousands of runs, never a forecast of one.

This is math, not a prediction. Real sessions vary wildly, and no strategy changes a game's built-in house edge. Play for fun, set limits, and never bet more than you can afford to lose.
