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.
Chinese playing cards
Playing cards () were most likely invented in China during the Southern Song dynasty (1127–1279). They were certainly in existence by the Mongol Yuan dynasty (1271-1368). Chinese use the word "pái" (), meaning "plaque", to refer to both playing cards and tiles. Many early sources are ambiguous if they don't specifically refer to paper "pái" (cards) or bone "pái" (tiles). In terms of game play, there is no difference; both serve to hide one face from the other players with identical backs. Card games are examples of imperfect information games as opposed to Chess or Go.
