Go (game)
Go is an abstract strategy board game for two players, in which the aim is to surround more territory than the opponent. The game was invented in China more than 2,500 years ago and is believed to be the oldest board game continuously played to the present day. 
A 2016 survey by the International Go Federation's 75 member nations found that there are over 46 million people worldwide who know how to play Go and over 20 million current players, the majority of whom live in East Asia.
Backgammon
Race board games involving dice have existed for millennia in the Near East and eastern Mediterranean, including the game senet of Ancient Egypt. The ancient Egyptian game senet was excavated, along with illustrations, from Egyptian royal tombs dating to 3500 BC. Though using a board that is quite different from backgammon, it may be a predecessor.
