Queens Logic Puzzle

Free · Designed for iPad. Not verified for macOS.

No ads. No timer. Place one shark in every color, row and column — and never let two touch. Every puzzle has exactly one answer, so pure logic always wins. 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}300 levels and a Daily Puzzle From a 4×4 tutorial board up to big 10×10 grids — 300 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}Hints that explain why Stuck? A hint points to the next cell to cross out or the next shark to place, and tells you why. Hints and answer help 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. Placing a shark crosses out the cells it blocks automatically (you can turn this off 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. 12 languages: English, 한국어, 日本語, 繁體中文, Español, Português, Deutsch, Français, Русский, Bahasa Indonesia, ไทย, Tiếng Việt No sign-up. Your scores appear only under an automatic anonymous nickname.
