## What is MASYU?

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.

Features
◆ Four difficulties (Easy / Medium / Hard / Expert)
◆ A fresh Daily Puzzle — the same board for everyone, every day
◆ Every puzzle is uniquely solvable, verified by a real solver—no guessing required
◆ Fully offline, no account, no sign-up
◆ A gentle hint for when you're truly stuck
◆ Records & streaks: solves, best times, no-hint rate, daily streak
◆ Calm, paper-and-ink design in indigo and vermilion
