Egyptian Ratscrew (also known as Egyptian Ratslap, Egyptian Ratkiller, Egyptian War, ERS and by other names) is a card game of the matching family of games. The game is similar to the 19th century British card game Beggar - My - Neighbour, with the added concept of "slapping '' cards when certain combinations are played, similar to and perhaps borrowed from Slapjack.
