Board games are among the oldest games we know of in the world. In Egypt, boards for games were found, carved into roofs of a temple at Kurna, dating to 1,400 BC. The oldest game we know of was called Senet, found in the Tomb of Merknera, Egypt. This dates to 3,300–2,700 BC. It is not exactly clear how to play it. Another contestant for being the oldest board game is Go, still played today. It is a Far Eastern game with only a few very simple rules but such complex strategy that many players dedicate their entire lives to its mastery. Other very old board games are backgammon: a 5,000 year old board was excavated in Southern Iran, in the Burnt City in the province of Sistan-Baluchistan. It was made of ebony and was found with a terracotta container which held 60 playing pieces.
