The essentials of playing 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. Begin with the local / basic computer mode shown on the page. Keep the game area visible while you use its controls.
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
Choose one rule to keep in mind for this round. Apply it consistently rather than guessing what another version might allow. Notice the feedback after each input.
The objective of a round
Checkmate the opposing king. Keep that objective in view throughout the round. Start with a deliberate move.
A walkthrough of the rules

- Choose a piece and a legal target.

- Undo or New game restarts play.
The controls to know
Tap a piece and target; choose a promotion piece when needed. Use the control method described here for this activity. A new-round button replaces the current round.
A useful example
Castling cannot pass through an attacked square. Use the example as a guide rather than a substitute for reading your board. Check the stated objective.
One detail worth checking
The computer is a small search opponent, not a rated engine. A different version of the game may use a different rule. After a move, check what changed. Decide which rule explains the new state before acting again.
