Release the Kraken RTP and Volatility

9 

The RTP of the game is 96.5% and the volatility is high.

The return percentage is a number that reflects the amount of the player's bets, which they can return when they finish spinning the reels of the slot. It is worth noting that this figure refers to the statistics of the title, so you can only expect a refund in theory. For RTP to work, you will need to make 1,000 or even more spins without interrupting your gaming session.

Volatility is an indicator that determines the amount of winnings. If it is high, then you can count on big prizes. However, do not forget about luck, it determines everything here.

Theme

9.8 

The game has indescribably colorful and very high-quality graphics that attract attention at first sight. The playing field is located against the backdrop of the seabed landscape, where colorful algae sway lazily under the action of the current and mysterious inhabitants dart. In the foreground, you can see a sunken sailboat that dragged a real Kraken to the bottom.

He himself lives in the depths of the ship's wreck, guarding his treasures and waiting for incautious explorers. Having the Kraken help you find wealth is hard, but it's possible! The game also has an excellent musical accompaniment, which perfectly conveys the tense atmosphere of the slot.

The title symbols are a series of card elements from J to A, as well as Clownfish, Ruff, Turtle, and Shark. The most profitable among the symbols is a sealed box, in which, according to legend, the bloodthirsty Kraken sat down.

The regular Wild is made in the form of an air bubble. The 3 bonus symbols are the Sailboat, the Steering Wheel, and the Chest. There are also 3 additional Wilds here, depicting a freed and very unhappy Kraken.

I decided to play this slot after I’ve spun its sequel, lol. Kinda reminds me how I’ve watched the Terminator movie.
Well, original version is a bit different from the sequel, but only a bit. Just like the sequel, it offers 3 wild features and free spins with multiplier. But there is also additional pick bonus with instant prizes.
Sadly, there are ante bet to increase ur chances of getting features. It’s not like wild features occur that rarely, bit with FS it’s different story.
