“Recreational Mathematics” is a problematic expression. For some people, like most professional mathematicians, Mathematics is lots of fun; but for others, like some students, Mathematics can be a nightmare.<\/p>\n
Historically, we know that some mathematical research areas are deeply linked to puzzles and games : probability and chance games, graph theory and the Brigdes of K\u00f6nigsberg come to mind.<\/p>\n
