Nim is a classical, simple game of logic and strategy, but with finite possibilities. The rule is that you may remove as many matches within a row in one move. The looser is who removes the last match on the table. There are several variations of the Nim game, including different objects, rules (winner is the one that removes the last object), number of rows of objects, max number of objects that can be removed at a time, and amount of objects. Good luck!
