I like the game Clue (called Cluedo in some parts of the world). I played it with my family when I was young, and we always had a great time. In college I wrote several programs to try to deduce what cards players were holding, but there was always some deduction my program missed. I started thinking about Clue again recently, and found much to think about. Frankly, this was a bit surprising to me! Isn’t Clue pretty straightforward?
