Binero: Binary Sudoku

Binero is binary sudoku: a pure logic game in black and white — also known as Takuzu or Binairo. 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.
