Gobstones
An ancient wizarding game, Gobstones resembled marbles and was played with special stones that squirted a vile liquid at the player who'd lost a point. The game would begin with fifteen Gobstones per player and the aim of the game was to win all of the opponent's stones. While the game's popularity didn't quite reach the heights of Quidditch, both Hogwarts and the Ministry of Magic had a Gobstones Club.
