Chessboard
Board games have been known since ancient history, with the oldest records being paintings in mastabas of the First and Third Dynasties of Egypt (3100-2700 BC). The first known version of chess appeared around the 6th century in India and was called Chaturanga, played on a board of the game Ashtapada. This board was monochromatic and divided into eight columns by eight rows, with special marks called "castles" in the first, fourth, fifth, and eighth squares of the "a", "d", "e", and "h" columns, which served a function in Ashtapada, but not in Chaturanga.
List of best-selling game consoles
A handheld game console is a lightweight device with a built-in screen, games controls, speakers, and has greater portability than a standard video game console. It is capable of playing multiple games unlike tabletop and handheld electronic game devices. Tabletop and handheld electronic game devices of the 1970s and 1980s are the precursors of handheld game consoles. Mattel introduced the first handheld electronic game with the 1977 release of "Auto Race". Later, several companies—including Coleco and Milton Bradley—made their own single-game, lightweight tabletop or handheld electronic game devices. The oldest handheld game console with interchangeable cartridges is the Milton Bradley Microvision in 1979. Nintendo is credited with popularizing the handheld console concept with the Game Boy's release in 1989 and continues to dominate the handheld console market.
