Chess Online: rules and examples
Try Chess Online at your own pace and keep its objective in view. Checkmate the opposing king. Keep the game area visible while you use its controls. Begin with the local / basic computer mode shown on the page. Choose a clear next step rather than rushing through the instructions.
Play on one device with a friend or against the basic computer opponent. Repetition and the fifty-move rule trigger an automatic draw here; there is no internet matchmaking or tournament clock.
Bring this focus to a round
Locate the buttons and input area before beginning a long round. Use the on-screen labels to avoid an accidental restart. Keep the objective visible.
The goal to keep in mind
Checkmate the opposing king. An attractive position is not enough unless the goal is met. Return to the instructions when a step is unclear.

Castling cannot pass through an attacked square. Your next round may have a different position, so inspect it before acting. Keep the game’s format in mind.
Where a round can go wrong
The computer is a small search opponent, not a rated engine. Take a moment to reassess the position before continuing. Watch the feedback after an action. A message can explain whether the input was accepted or whether a rule needs attention.
