Acknowledgments

This site would not be possible without a lot of help, especially from the following:

  • Jim Bumgardner (krazydad) whose excellent site http://krazydad.com provided many
    hours of enjoyment and inspired me to create puzzles of my own. He has also
    been very generous providing tips and support.
  • Yochanan Dvir whose cross-figure puzzles formed the reference material for the puzzles.
  • Jared McComb (bosuonparedo) who started me down the path to create the hexagonal puzzles.
  • Phil Bordelon (Sunfall) who suggested the name TripleCross.
  • Dave Millar (Taco Dave) who suggested I create books.
  • All the users on the krazydad discord server who tested the puzzles and gave feedback.
