Masyu Puzzles

Masyu is one of the more popular logic puzzles, appearing regularly at puzzle competitions. In Masyu you start with a rectangular grid in which you must draw a non-intersecting loop passing through some of the squares, following two simple rules:

  1. the loop must pass through all black squares and make turns there
  2. the loop must travel straight through all white squares, but make a turn right before or after passing through them

The Masyus below (sorted by difficulty) are shared by KrazyDad, a website with thousands of various types puzzle problems.
