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.
Blue and Gray (board game)
Blue and Gray is a strategy board game for two players invented by Henry Busch and Arthur Jaeger in 1903. They obtained a patent for the game, but may never have published it. Blue and Gray was featured in the book "A Gamut of Games" (1969) by Sid Sackson. It was also featured in "The Book of Classic Board Games" (1991) by Klutz Press under the name Cats and Dogs. In this book, the game was ranked among the top 15 board games of all time, including checkers, backgammon, Go, and mancala. The game is also known as Wild West, Thumps Game, and Captain and Soldiers. The name Blue and Gray "refers to the uniforms of the South and the North in the Civil War and in the original game the playing pieces of the contestants were of those colors."
