Chess By Post is a real-time multiplayer version of chess. Players take turns moving pieces on an 8×8 board, and the goal is to checkmate the opponent’s king.

This is an online version of the game, which means you can play with people all over the world. You can challenge your friends to a game of chess or play with random opponents of similar skill levels.

The game is perfect for players of all skill levels because your matched opponent’s skill level will be adapted based on your own skill level.
