HOW TO USE THE HINTS

My puzzles contain a page of hints in addition to a page of answers.

The hints are puzzles grids that contain numbers showing the order in which the squares were solved by the computer. Although this is not necessarily the order you would solve the puzzle, it's probably pretty close.

Follow the numbered squares in order 1,2,3,4,5... until you find a square you haven't solved yet. This square (or the one or two immediately after it) is a good candidate to solve next.

Feel free to reproduce the puzzles for personal or school use. If you would like to publish these, or similar puzzles in a newspaper or book, or would like a larger or different selection of puzzles, contact me at dad@krazydad.com.
