About
Fill the grid with moons and suns. Every row, every column, three simple rules — and a surprising amount of depth.
Binary Puzzle (also known as Takuzu or Binairo) is a quiet logic game with rules you learn in seconds:
• Each row and each column must contain the same number of moons and suns.
• Never three identical symbols in a row — horizontally or vertically.
• No two rows may end up identical. The same goes for columns.
That's all. From there it is pure deduction: a row that already has its quota of moons forces suns into every empty cell, two identical symbols side by side force the third, and a nearly finished row that would duplicate another row can only end one way. No guessing. No luck. Just logic.
