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.
GreatSlots review · Pragmatic Play · 2020
Release the Kraken is heavier than a simple sea-monster reskin. The base game can throw random Kraken modifiers onto the reels, while the bonus round leans on roaming wilds and a progressive multiplier to create the real pressure.

Best for
players who like random wild events and dark ocean themes
A strong fit for players who want a feature-led ocean slot with more atmosphere than the average 5x4 line game.
Release the Kraken works because its ocean theme is tied to visible reel events: random wild modifiers, a treasure bonus, and roaming wild free spins.
Release the Kraken uses a 5x4 board with 20 fixed paylines. Line wins are straightforward, but the game adds drama through random Kraken events that can change how wilds behave on the reels.
The free-spin side is where the slot becomes more distinctive. Roaming Kraken Free Spins can reveal hidden spin counts, then use roaming wilds and a progressive multiplier to build pressure. The Sunken Treasure Bonus adds another route to multiplier value, so the slot feels more event-driven than a normal underwater line slot.
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 a higher ceiling without switching to a Megaways board.
It is less suitable for players who want every result to be obvious at a glance. The slot is readable, but it asks you to follow multiple Kraken modifier types and a more involved free-spin structure.
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.

Bigger Bass Bonanza keeps the fishing collection loop simple, then raises the pressure with a taller 5x4 board, larger money values, and retriggered multiplier steps.

Great Rhino Megaways stands out because the bonus pick changes both spin count and multiplier risk, which gives the feature more shape than the average safari reskin.
The main feature mix is random Kraken wild modifiers, the Sunken Treasure Bonus, and Roaming Kraken Free Spins.
Yes. Its feature-led design and 10,000x max-win ceiling make it a clearly high-volatility slot.
No. The original Release the Kraken uses 20 fixed paylines; Release the Kraken Megaways is a separate sequel.
