Release the Kraken is an underwater slot from Pragmatic Play on 5 reels and 4 rows with 20 paylines. Random wild features can strike on any spin, a chest picking bonus pays instant prizes, and the free spins round doubles the paylines to 40 with a multiplier that grows each time a wild lands. It suits you if you like varied features and a game with several ways to hit a bonus.

How does Release the Kraken work?

Wins pay from left to right on 20 paylines across a 5x4 grid. Sea creatures and treasure make up the symbols, with the Kraken wild substituting for regular symbols.

On any spin, the Kraken can appear and offer you three tentacles. The one you pick triggers a random wild feature: Lock-in Wilds, a Colossal 3x4 wild, or Infectious Wilds that spread across the reels. Bets run from 0.20 to 100 per spin.

The random features are what keep the base game busy. The Colossal Kraken wild covers a 3x4 block of the grid, while the Lock-in and Infectious versions add wilds in other ways. Each one gives a regular spin a better chance to pay, so the base game has more going on than a plain line slot.

What are the Release the Kraken bonus features?

Bonus symbols on reels 1 and 3 plus a chest on reel 5 start the Sunken Treasure bonus. You open chests for cash prizes until a Collect symbol appears.

If reel 5 shows a free spins symbol instead, you get the Roaming Kraken free spins. Chests add extra spins, often for a total around 10. In this round the game uses 40 paylines, and the win multiplier starts at 1x and rises by 1 every time a wild lands.

The two bonuses use the same trigger on reels 1 and 3, and the symbol on reel 5 decides which one you get. The free spins round usually offers higher potential because of the growing multiplier.

Is Release the Kraken worth playing? RTP and volatility explained

Pragmatic Play lists the RTP as 96.50%. Lower versions of 95.50% and 94.50% are also offered, so check the game info at your casino.

Volatility is high, and the max win is 10,000x your stake. The random wild features give the base game more action than many line slots, but the largest wins come from the growing multiplier in free spins.

Tips before you play Release the Kraken

  • Confirm the RTP version before playing.
  • Try the demo to see how often each of the three random wild features appears.
  • Plan for stretches where neither bonus lands.
  • Note that free spins use 40 paylines instead of 20, which helps the growing multiplier pay out more often.
