A practical guide to Chess Online
Choose a round of Chess Online and settle into its rules. Checkmate the opposing king. Use the example below to understand a decision. Read the objective before making your first input. Look at what changes after your first action.
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.
Try a more deliberate round
When a decision goes wrong, compare it with the common mistake described below. Start again only when you intend to leave the current round. Use the example to check your reasoning.
Your goal
Checkmate the opposing king. The feedback beside the game helps you follow the round. Follow this game’s rules rather than another version’s.
The order of play
- 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.
Controls
Tap a piece and target; choose a promotion piece when needed. A careful first action helps you become familiar with the layout. Use one clear input at a time.
A useful example
Castling cannot pass through an attacked square. Compare this with the rule that governs the move. Keep the game’s format in mind.
An important reminder
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.
