Play chess against a computer opponent — full rules, right in your browser.
Your move (White)
Chess is the definitive strategy game: two armies, perfect information, and more possible games than atoms in the observable universe. This version lets you play a full game against a computer opponent that thinks a few moves ahead — with all the real rules, including castling, en passant, pawn promotion, and check, checkmate and stalemate detection. You play White and move first.
It runs entirely in your browser with a click or a tap: select one of your pieces to see its legal moves highlighted, then choose where to go. There is nothing to install and no account needed — just open the board and play.
