# Exhaustive list of recreational mathematical concepts

There are many simple yet elegant, addictive and entertaining mathematical concepts. For example, drinker paradox, pigeon hole principle, Monty Hall problem, Hilbert's paradox of the Grand Hotel, etc.
Can somebody please provide me with a list of such recreational mathematical concepts?

This is a pretty good start: en.wikipedia.org/wiki/Category:Recreational_mathematics –  Matthew Conroy May 30 '14 at 17:34
@MatthewConroy I want to read more about principles and paradoxes than problems. –  shaurya gupta May 30 '14 at 17:38
You're welcome! That page has links to many Wikipedia pages, including pages on principles and paradoxes. Wikipedia is very interconnected, so, for instance, from the page on the Homicidal chauffeur problem, you will see links to Variational Calculus. For paradoxes, check out en.wikipedia.org/wiki/Category:Paradoxes Cheers! –  Matthew Conroy May 30 '14 at 17:45
