Learn the rules of Chess Online
Take a moment with Chess Online before moving to another game. Checkmate the opposing king. Use the example below to understand a decision. 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.
A small practice goal
Read one step at a time and try it on the playing area. Match the instruction to the control you use. Make the next step deliberately.
What you need to achieve
Checkmate the opposing king. Use the instructions to see which actions move you towards it. Check the rules when you are unsure.
Follow these playing steps
- 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.
How to use the controls
Tap a piece and target; choose a promotion piece when needed. Keep the playing area visible while using these controls. Avoid pressing the same control repeatedly while a move is being processed.
See how the rules apply
Castling cannot pass through an attacked square. Apply the same reasoning to the position in your own round. Keep the game’s format in mind.
A useful caution
The computer is a small search opponent, not a rated engine. Compare the situation with the worked example. Locate the buttons and input area before beginning a long round. Use the on-screen labels to avoid an accidental restart.
