Masyu - Pearl Loop Puzzle

Masyu is a quiet kind of puzzle: you draw a single loop that winds through the whole board, passing straight through the white pearls and turning at the black ones. There's something satisfying about watching one line slowly close on itself.

Every Masyu board in this app is generated on your phone and has exactly one loop that solves it, reachable by pure deduction. You won't hit a point where the only way forward is to guess and backtrack. Finish a board and the next one is already waiting, so the supply doesn't run out the way hand-made puzzle packs do.

• Tap between dots to draw or erase a segment of the loop
• Undo and redo as you try out a path
• Boards range from a compact 6x6 to a slower 10x10

You don't sign in and it needs no connection, so it's there on a flight or during a break. The screen is just the board and your loop, nothing competing for attention while you think.

Made for people who like Slitherlink or Nurikabe and want a loop puzzle with its own feel.
