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.
Cat's cradle
Cat's cradle is one of the oldest games in recorded human history, and involves creating various string figures, either individually or by passing a loop of string back and forth between two or more players. The true origin of the name is debated, though the first known reference is in "The light of nature pursued" by Abraham Tucker in 1768. The type of string, the specific figures, their order, and the names of the figures vary. Independent versions of this game have been found in indigenous cultures throughout the world, including in Africa, Eastern Asia, the Pacific Islands, Australia, the Americas, and the Arctic.
