Egyptian Ratscrew

Egyptian Ratscrew, sometimes abbreviated to ERS and also known as Egyptian War, Bloodystump, Ratslap or Slap, is a modern American card game in the matching family that is popular among children. It resembles the nineteenth century British card game Beggar-my-neighbour but adds the element of slapping certain card combinations when they are played, and this slapping idea may have been borrowed from the game Slapjack. Players race to notice patterns in the cards as they fall, so quick reactions matter alongside the plain card play.
