High Quality Content by WIKIPEDIA articles! Poohsticks is a game first mentioned in The House at Pooh Corner, a Winnie-the-Pooh book by A. A. Milne. It is a simple game which may be played on any bridge over running water; each player drops a stick on the upstream side of a bridge and the one whose stick first appears on the downstream side is the winner. The annual World Poohsticks Championships have been held at Day`s Lock on the River Thames in the UK, since 1984.
