Binary Puzzle

Binary Puzzle is the classic Takuzu logic grid dressed in cheerful suns and moons. Every puzzle has exactly one answer you can reach by pure deduction, with no guessing needed. Each run takes you from a tiny 4x4 to a tricky 8x8, and the faster you solve, the more you score.

How to play

  1. Tap a tile to cycle sun, moon, empty.
  2. Fill each row and column with equal suns and moons, never three alike in a row. From the third puzzle, no two rows or columns may match.
  3. Solve all four puzzles; the faster you go with fewer hints and checks, the higher your score.
