Chess By Post recreates the tradition of correspondence chess, but updated for the 21st Century. While it might seem simple at first, Chess By Post reveals itself to be a seriously competitive game, with modes including: Facebook friend games, passing the device used between players IRL, finding an in-game username and ranked matches. The ranked matches might mean playing anyone on the game, and is based on an in depth personal ranking system. Also, this is cross platform so anyone on any device can play with anyone else.
