Board games are games played with counters or pieces that are placed on, removed from, or moved across a board. They simulate aspects of real life or attempt to imitate reality through abstract strategy games, word games, and other types. The oldest known board game dates back to ancient Egypt in 3300-2700 BC. Board games became widely popular in the early 20th century as the middle class had more leisure time. Nowadays, many board games are available as computer games and can be played online.
