N, B, R & Q Tours

Going beyond the knight's tour, this PDF discusses the Bishop's Tour, Rook's Tour, and Queen's Tour, introducing a rule that gives these puzzles real play value.  Also, Frezco is pleased to present a way to turn any of the tours into a game for two.
A PDF with nothing but blank chess boards for trying out the tours.
You can use this to solve a tour or create a puzzle and then take a screenshot and save it as a JPG.
