Some of My Favorite Puzzles

What's the Point for a cube

These are puzzles that I have either invented or “acquired” over the years. I have avoided problems that have appeared many times in other puzzle books (You have 12 coins, one of which is either light or heavy...). The puzzles are presented here without solutions because, of course, the joy of a puzzle is in the solving, not in the answer. If you have questions about any of these, if you need a hint, or if you would like to share solutions or other insights, please send an email to deanbal (at) comcast (dot) net.
