About this game

Binero — also known as Takuzu or Binairo — is a pure logic game in black and white. Fill the grid with 0s and 1s by following a few simple rules. Never any guessing: every puzzle has a single solution you deduce, cell by cell.

HOW TO PLAY
• Tap a cell to cycle empty → 0 → 1.
• Never more than two identical digits in a row.
• Equal numbers of 0s and 1s in each row and column.
• All rows — and all columns — are different.

Four rules you grasp in 30 seconds… and puzzles that keep your mind busy for hours.

WHAT'S INSIDE
• Story mode: 50 levels with a gently rising difficulty, from 6×6 to 14×14.
• Daily puzzle: a new challenge every day, in nightmare mode (14×14).
• Adaptive difficulty: the game adjusts to your level.
• A hint when you're stuck, plus optional mistake highlighting.
• Global leaderboard via Google Play Games.
• 100% offline, no sign-up.
• Clean, calming design — Android phones and tablets.

WHY YOU'LL LOVE IT
Binero is the relaxation of sudoku, but in binary: crystal-clear rules, pure logic (you never guess) and that little thrill when the grid completes itself. Perfect for a break, to sharpen your thinking or simply to unwind.
