Midway into a spin, a glowing square drops over four rows of the grid, a Kraken lands in it, and the pirate swells to cover every cell. Kraken’s Sky Bounty slot builds its main game around that Random Expanding Wild. A marked block of 2×2 up to a full 6×6 lands on the reels, and any wild that arrives in the block turns giant, with a multiplier stacked on top when two or more wilds share it. It plays out on a 6×6 grid of 50 lines, set aboard a pirate ship sailing the clouds.
At random, a highlighted square lands across the reels, ranging from 2×2 to a full 6×6 block. Any Kraken that lands inside expands to fill the marked area, playing as all but the airship bonus. If multiple wilds land in the same square, the resulting block gains a multiplier equal to their number. It shows up regularly in the base game and can turn large sections of the grid into potential winning combinations.
Hit 3 or more airship bonus symbols and 6 free spins begin, the sky darkening to night with lightning flickering in the clouds.
The square will be in view each spin now, jumping to a fresh spot each time and starting small at 2×2. Each bonus symbol you collect is stored, and every third one retriggers the round for 2 more spins while the square grows a size, from 3×3 to 4×4, 5×5 and the full 6×6. Collecting stops after the fourth retrigger.
If you land 4, 5 or 6 airships to trigger free spins, the round will start with 1, 2 or 3 bonus symbols already collected.
Two shortcuts sit beside the reels. The Ante Bet adds a fifth to your stake, a 30x bet against the standard 25x, and, in exchange, ensures more airships on the reels and therefore a better chance of triggering the round on its own. A Buy Free Spins button skips the wait for 100x your total bet, dropping 3 to 6 airships onto the opening spin. The two are mutually exclusive, so switching the Ante Bet on turns the buy off.
The 6×6 grid packed with coloured gems looks like a cluster-pays game at a glance, the sort where matching symbols wherever they land pay out. Kraken’s Sky Bounty is not that. It uses 50 fixed paylines, and wins pay the usual way, with three or more matching symbols that connect from the left of the grid. The Kraken plays as every symbol but the airship bonus, helping the lines pay.
The stake spans $0.25 to $250 a spin, with the Ante Bet adding 20% on top. The published RTP is 96.05%, ticking up to 96.06% with the Ante Bet on and 96.07% if you buy the round. Operator versions go as low as 94.05%. Volatility is high, and a single game tops out at 5,000x the stake, in the base spins or the free spins alike. Reach that cap and the round ends there.

Pragmatic Play has put its effort into the surface here, and it shows. Kraken's Sky Bounty looks and sounds a cut above the 50-line game underneath, with a pirate ship firing cannons into the clouds, a Kraken draped on the reels, and a bouncy sea-shanty tune that sells the mood. The base game is a plain paylines game, and the one feature doing real work is the Random Expanding Wild, which keeps the reels lively where the paytable alone would go flat. There is no deep bonus and little you have not met before. The presentation and that wild are what earn its score in our review.
The presentation is the standout. Its flying-ship-and-Kraken theme is drawn with clear care, and the symbol animations have real personality. Swords clash, the wheel spins, cannons fire, and the gems pop off the grid and slam back down in a burst of their own colour. The pirate music wears well over a long session. The expanding wild is the mechanical draw, dropping regularly and stacking a multiplier when several wilds share a square. Free spins build nicely too, the square growing and the round stretching out as the airships collect.
There is not much game beneath the theme. It is a conventional 50-line slot with one base feature and one bonus round, so once the early shine settles there is little else to discover. With just the one feature to lean on, the paid spins can sit quietly between expanding wilds, and a 5,000x cap is modest for a high-variance Pragmatic release. The free spins can fizzle too when the square lands away from your wilds, so a big square is no guarantee of a big win.
Load it up, and the theme does the talking. A pirate ship hangs in a bright sky off to the right. Its cannons go off, and plumes of orange fire drift past the reels. The Kraken itself, a grinning pink octopus in a captain’s hat, sprawls at the edge of the grid, its tentacles spilling into the bottom rows. Its name is no accident; the word Kraken sits in the logo, and the creature is your wild. Coloured gems pack the grid, and for a moment it reads like a cluster game, before the 50 paylines and the left-to-right wins set you straight. The cartoon art is crisp, and that bouncy tune lodges in your head.
In the base spins the expanding wild is the thing to watch. A marked square lands on the reels from time to time, and when a Kraken drops into it the pirate swells to fill the block, with two or more bringing a multiplier along. It shows up enough to shape a session, and more than once it turned a dead-looking spin into a paying one. Between those moments the reels lean on the gems and the higher pirate symbols, and they can stay quiet. That is where the animated wins earn their place, each symbol putting on its own small show as it pays, doing a lot to hold your attention.
A trio of airships sets off the free spins. An arcade-style bell rings, a cannonball crashes in from the side, and the sky turns to night with lightning in the clouds. Ours started on a 2×2 square and grew from there. Two retriggers added 4 spins and pushed the mark to 4×4 as the airships piled up. The last spin was the one that paid, a 4×4 square and a multiplier combining for $165.20 on its own, and the round closed at $201.52. That is the game at its best. The quieter rounds do not pay like it, but they are still a pleasure to sit through. You do not need to be a pirate fan to enjoy Kraken’s Sky Bounty, and the free play demo lets you test whether its expanding wilds fall your way before you spend anything.
