About Masyu
Masyu is a Nikoli loop puzzle, sometimes called Pearl. White and black pearls each set one simple rule for the loop, and a handful of them is enough to pin down a single path through the whole grid.
Practice puzzles come in three sizes and never run out. Like the daily one, each has exactly one solution you can reach by logic alone.
