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.
Indoor games and sports
Games such as Monopoly and backgammon are a mixture of chance and skill. Even though luck (usually the throw of dice) plays a part, choices made by the players in the course of the game also help to decide the winner. Backgammon is one of the oldest board games that people still play. Its name comes from the Saxon (it means ‘back game’ because sometimes pieces have to go back to the beginning), but the Romans played this game too.
