Masyu Puzzles by KrazyDad

Here are hundreds of free Masyu puzzles suitable for printing. Each Masyu puzzle has only one unique solution.

January 2015 Note: I have swapped out my old Masyu collection for a new one I've made which includes puzzles of greater difficulty. You'll find the books get progressively more difficult as the book numbers progress from 1 to 100, and I now offer "Medium" difficulty puzzles, and a few new sizes. These are the same Masyu puzzles I am offering on my new Interactive Masyu page. You may also notice that the visual format has changed. I am now drawing the puzzles in the Slitherlink style, using dots instead of a grid. This uses less ink, and makes the rules a little easier to explain.

Here's a tutorial on how to solve Masyu puzzles.


The finished puzzle will contain a loop made of horizontal/vertical line segments which connect the centers of grid cells.

  • Black circles indicate corners.
  • White circles indicate straights.
  • Black circles must be turned upon, but the loop must travel straight through the next and previous cells in its path.
  • White circles must be traveled straight through, but the loop must turn in the previous and/or next cell in its path.

Thanks to Simon Tatham, whose 'Pearl' code was the impetus for this collection.
