Strategy and tips

Four steps from your first game of Masyu to expert play.

  1. First game

    A black pearl must turn: the loop goes straight through the points on both sides of it.

  2. Getting better

    A white pearl goes straight. Next to it, the loop must turn at one of its neighbouring points.

  3. Confident

    A pearl on the edge of the board limits the loop: a black pearl there cannot turn toward the outside.

  4. Expert

    Every point has either no line or exactly two. When a point already has two, its other edges stay empty.

Common mistake Drawing an edge because a pearl seems to want it. A wrong line is not drawn and counts as a mistake; five end the attempt.
