One line. A clear mind. MASYU is a quiet logic puzzle: link every pearl on the board into a single loop that never crosses or branches. No numbers, no math—just two simple rules and your finger. Two rules, real depth - White circle ○: the line passes straight through, and must turn in the cell just before or after it. - Black circle ●: the line turns on the circle, and goes straight through the cells on both sides. From these two rules, surprisingly deep boards emerge.
