Pipe Quest vs Binairo

A challenging puzzle game.

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. ◆ THREE THINGS TO KNOW • Free to start, no subscription (one-time purchase only) • No third-party ads (only promotions for our own other apps) • Your records stay on your device (no account, nothing uploaded) ■ 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)
