ShakShakShak

No ads. No timer. Just cute sharks and a clever logic puzzle. Place one shark in every color region and one in every row and column — and sharks can never touch, not even diagonally. Every puzzle has exactly one solution, so you can always solve it with pure logic. No guessing.

{H}No ads No ads while you solve, no ads after you clear a level. No in-app purchases, either.

{H}Take your time There is no timer. Close the app whenever you like — your board waits right where you left it.

{H}Shak! ShakShak! ShakShakShak! Place sharks correctly in a row and the Korean shout 「샥!」 ("shak!") grows by one syllable each time. Three in a row and you hear the game's name.

{H}Chase real players The anonymous score just above yours shows up as your rival — as a clownfish, pufferfish, octopus, crab, sea turtle or jellyfish. Swim past them for bonus points.

{H}330 levels and a Daily Puzzle From a 4×4 tutorial board up to big 10×10 grids — 330 levels, with a small breather board every 10 levels. The first boards show you each rule step by step. Clear 10 levels to unlock the Daily Puzzle, a new board every day that grows bigger and trickier toward the weekend.

{H}Stuck? Hint. Slipped? Undo. A hint points straight to where the next shark goes. Placed a shark in the wrong spot? Undo it and get your heart back. After a tough level, open the Shark's solving notes to see the solution step by step, with the reason for each move. Hints and undos refill for free every day, up to a daily limit.

{H}A new sea every level Pacific, Atlantic, Indian Ocean, Red Sea, Mediterranean, Caribbean, Southern Ocean and Arctic — each level takes you to a different sea.

{H}Easy controls Tap once for an ×, double-tap for a shark, swipe to mark many × at once. On the first three levels, placing a shark crosses out the cells it blocks automatically; after that, you choose whether to mark × yourself or automatically (change it anytime in Settings).

{H}Good to know Placing a shark in the wrong cell costs a heart. Hearts refill over time, and the Daily Puzzle and tutorial boards never cost hearts.
