Razor Shark
Razor Shark is one of the sharper very-high-volatility picks in this set because it layers expanding systems and bonus upgrades without losing the core logic.
Paris Gamblers review · Pragmatic Play · 2020
Release the Kraken is the 2020 original in Pragmatic Play's sea-monster series. Its current provider page confirms a 4x5, 20-line format and 96.50% RTP, while the launch release identifies a treasure multiplier bonus, hidden free-spin awards and three named wild modifiers. The provider does not publish one universal volatility label, stake range or maximum win for this version.

The free-spins rules decide where the slot's value sits, especially when wilds, multipliers, or retriggers carry the upside.
Compare free spinsThe provider describes a 4x5 board with 20 lines and lists 96.50% RTP. Random events can introduce Infectious, Colossal or Locking Kraken Wilds, while the separate Sunken Treasure Bonus produces a sum of multipliers.
Roaming Kraken Free Spins begin with 10 hidden items. Every revealed free-spin award is added together before the round, where roaming wilds and a progressive multiplier become the main mechanic. Stakes, volatility, maximum win and any deployment-specific feature-entry option should be checked in the active information screen.
This suits players who like dark, atmospheric slots with several possible feature events instead of one predictable bonus loop. It also works well for players who want several named wild modifiers without switching to a Megaways board.
It is less suitable if you want one simple feature or a published provider maximum. Release the Kraken 2 and Release the Kraken Megaways are later separate games with different grids, wild systems and bonus rules; their values should not be applied to this original.
The mobile version is workable because the 5x4 grid stays compact, but the feature labels matter. It is worth checking the rules once so the different Kraken wild events do not blur together.

RTP mechanics guide
RTP is the theoretical long-run share returned as prizes by one game configuration. Actual RTP measures past results from a particular sample. Neither predicts the next spin; theoretical RTP does not predict a session, win frequency, or payout size.
Free-spins mechanics guide
Free spins are extra rounds awarded by an in-game feature. The paytable sets the trigger, starting spin count, retrigger rules, and any wild or multiplier changes.
Jackpot mechanics guide
A progressive jackpot starts from a preset value, grows through stake contributions, and resets after a win. A fixed jackpot stays at the amount or multiplier written in the rules. Neither label shows how likely the prize is to land.
