Three rules: fill the grid with 0s and 1s. No luck, no math, just logic. Stuck? The hint explains why a cell is decided. A daily puzzle and streaks build a calm habit. Fill the grid with 0s and 1s. Just three simple rules. Binairo — also known as Takuzu or Binary Puzzle — is pure logic: no luck, no math. And when you get stuck, the hint tells you why a cell is decided, not just what goes there. A calm, Japanese-inspired design makes a few minutes a day feel like a quiet reset. ■ HOW TO PLAY Put a 0 or a 1 in every cell, following three rules: - Never three of the same number in a row or column - Each row and column has equal 0s and 1s - No two rows and no two columns are identical ■ FEATURES - Every puzzle has exactly one solution (checked in-app before it's shown) - Four levels: Easy 6x6, Medium 8x8, Hard 10x10, Expert 12x12 - Daily puzzle: everyone plays the same one, with streaks and a calendar - Two styles: numbers (0/1) or two-color stones - Mistake highlighting, remaining counts, undo, and clear all - Explained hints that tell you the rule behind each move - Stats for solves, best times, and no-hint rate, plus 10 badges - Japanese-inspired board themes - A short, hands-on tutorial for first-timers ■ GREAT FOR YOU IF… - You love Sudoku and want a fresh logic puzzle - You prefer clean deduction over guessing - You want to learn the reasoning, not just get the answer - You want a calm mental break on the commute or before bed - You enjoy apps with a quiet, minimal look ■ PRIVACY - No account or sign-up - Puzzles are generated on your device, and you can play offline - Your records stay on your device and are never uploaded - No data collection - To show our other apps, Binairo loads public App Store info (names and icons)
