The game's setting at the ocean's depths makes it one of the best-looking titles to come off Pragmatic's assembly line in recent memory. Its 5-reel, 4-row layout is partially visible in front of a sunken galleon, which casts a foreboding shadow. From a user interface perspective, you can wager anywhere from 1-10 coins per line, with coin values ranging from 0.01 to 0.50. Bets can range from 10 pence to 100 pounds or euros every spin. The goal of the base game is to win money by lining up symbols on the 20 paylines. It's not Pragmatic Plays' most dangerous scenario, but don't let that fool you; with 4/5 lightning bolts, it's not far behind. Get ready to unleash the Kraken with a respectable RTP of 96.50% by default.


Pragmatic Play's Release the Kraken slot machine is a watery, monster-filled adventure. In case you haven't heard of it, the Kraken is a legendary mollusk made famous by Moby Dick and 20,000 Leagues Under the Sea. Both works came out in the 19th century, although the Kraken myth goes back much further in time. It was first mentioned in the Norse Sagas, where it served to strike fear into the hearts of mariners for generations. Pragmatic Play's continuation of the trend sees them creating a slot that may both pay out large and give you nightmares after a particularly rough session.

Symbols & Payouts

There are nine regular symbols on the payoff table of the Release the Kraken slot machine. The standard playing card symbols are, of course, included. It's important to note that you can only win if three, four, or five of the identical icons land on a line before we go into the rewards. In the event that you obtain three, four, or five Jacks or Queens, you will receive 5, 10, or 40 times your line bet, respectively. Contrarily, getting a pair of Kings or an Ace on a payline will result in a payout of 10, 20, or 80 times the line stake.

If you catch three or four blue fish or four yellow fish on a line, you'll win 20 or 60 times your line wager, respectively. Catch five yellow fish, and you'll win 100 times your line bet, and catch five blue fish, and you'll win 150 times your line bet. Five sea turtles on a line pays out 200 times the line bet, and five sharks pays out 250 times the line bet. If you get three, four, or five of the game's logo on an active payline, you'll win 50, 200, or 500 times your original wager.

Keep in mind that the Wild symbol is also a paying icon; in fact, it pays the same way the slot's logo does.

RTP & Volatility

The Release the Kraken RTP is 96.5%. That’s higher than many other slot games found today. Also, this is a high volatility game that pays out less often on average, but the chances to get big wins in a short period is higher.

How To Play

Although Release the Kraken's rules and mechanics are quite straightforward, we felt it was necessary to provide a beginner's tutorial to the game for anyone interested in wagering real money. An easy-to-follow breakdown of the game's mechanics is provided below:

  • Find the game & launch it – Simply use the site's search bar to zero in on Release the Kraken, a fun slot machine.

  • Paylines – Decide how many of the available paylines you want to use.

  • Bet size –Pick out a wagering amount.

  • Spin it – Put the disc in spin mode.

  • Collect – When you win, your prize money is automatically transferred to you.

You can’t miss the play button in this game – it’s an animated button on the right side of the screen. When you press that button, the five reels, 20 paylines, and four rows per reel will start moving. You might want to change the size of your bet before playing too. You can choose the number of coins per line – a minimum of 1 coin and a maximum of 10 coins. Next, you can choose the value of these coins that starts with €0.01 and ends with €0.5. So, if you use the maximum values, you can bet with €100 per turn.

Auto-play, sound on/off, and access to the pay table and bonus features are all available in this slot, as they are in most other slot games. After you've spun the wheels a few times, you'll be able to see details about your previous wagers.

Remember that slot games could quickly finish all of your savings if you don’t learn to control yourself. Otherwise, things could end badly. Most casinos where you can play Release the Kraken online provide the opportunity to set personal limits and prevent yourself from spending too much.

Roaming Kraken Free Spins

These moments could prove to be game-changers. When the Free Spins Symbol appears on Reel 5 and the Bonus Symbols appear on Reels 1 and 3, you will activate this bonus round.

A Beast Beneath the Wave

Slot machine action in Release the Kraken takes place across five reels, each of which can display four different icons. There are 20 lines total, and they go both to the left and the right. Animated bubbles rise from the seafloor while vibrant corals behind the reels sway in the water. The undersea scenery in Release the Kraken is beautiful, and our reviewers found the game to be on par with others in its genre.

You can choose to listen to the mechanical slot machine sound effects, the orchestral music, or both at the same time as the reels spin. In practice, we see standard playing card icons, which look out of place. Animals like the fish, turtle, and smiling shark from Finding Nemo are much more endearing. Krakens are frightening creatures in and of themselves, with glaring eyes, vicious fangs, and an exposed purple brain. It has more in common with Predator than Pixar. This Is the Freedom Pragmatic Play, a major developer of slot machines for casinos all around the world, is responsible for the Kraken online slot. It can now be found among other online favorites including "Journey to the West" and "8 Dragons."

Anchors Aweigh for Bonus Features

The game logo pays out 500x your line bet when it fills a payline. The wild symbol of the Release the Kraken slot machine is a big bubble that can inflate your bankroll by acting as others if needed. If three tentacles appear, you click one to trigger an in-game bonus. The Kraken Lockin Wild feature sees the reels respinning, while treasure chests add extra wilds or additional spins. Prizes are paid at the end of the reel respins when you could have multiple wilds across the reels of the Release the Kraken slots game.

Colossal Kraken Wilds is a quick feature where the beast appears as a 3x4 wild symbol, almost guaranteeing some big wins. In the Infectious Kraken Wild feature, at least one wild symbol will reach out and turn adjacent tiles into further wilds. Keep a sharp lookout for bonus symbols landing on reel five at the same time as the ship sails onto reels one and three. The Chest Bonus symbol tasks you with picking prizes from treasure chests. You carry on until one opens to reveal ‘Collect’ and all accumulated rewards get paid. 

The Free Spins symbol starts a bonus round, but before they begin, you pick chests to collect several free games until you hit ‘Collect’. The spins then play out over 40 paylines with each wild appearing adding a win multiplier of 1x. Wilds also stay on the reels, moving around with each free game.

5 reels + 20-40 paylines

Highest Payout

The payout ceiling is rather large at 10,000 times the initial wager. That would result in a maximum payout of €750,000! It's no secret that Pragmatic Play games have huge jackpots (for example, Peking Luck with a maximum win of 180,000x the bet or Buffalo King with a bullish top prize of 93,750x the total bet).

The Pragmatic Play method has taught us that these are purely hypothetical figures. The odds of winning the jackpot are one in a hundred billion. Since Release the Kraken has a medium to high variance, payouts of around 1,000x the wager are rather common.

Our Verdict

If you want to have fun with Release the Kraken, you should like unlocking treasure boxes because the game is packed with them. The progressive free spins multiplier is the key to higher wins, but the game's extreme volatility will force you to sit through some painfully long dry spells.
