A practical guide to Chess Online
Chess Online gives you a focused activity to play in your browser. Checkmate the opposing king. Look at what changes after your first action. 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.
Practice beyond the first move
When a decision goes wrong, compare it with the common mistake described below. Start again only when you intend to leave the current round. Keep the objective visible.
What you need to achieve
Checkmate the opposing king. The feedback beside the game helps you follow the round. Follow this game’s rules rather than another version’s.
From the start of a round
- Select local play or basic computer.
- Choose a piece and a legal target.
- Castling, en passant and promotion obey king-safety rules.
- Use the promotion selector before moving to the last rank.
- Undo or New game restarts play.
Input guidance
Tap a piece and target; choose a promotion piece when needed. A careful first action helps you become familiar with the layout. A new-round button replaces the current round.
See how the rules apply
Castling cannot pass through an attacked square. Compare this with the rule that governs the move. Check the stated objective.
Where a round can go wrong
The computer is a small search opponent, not a rated engine. Compare the situation with the worked example. Watch the feedback after an action. A message can explain whether the input was accepted or whether a rule needs attention.
