How to play Chess Online
Chess Online gives you a focused activity to play in your browser. 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.
A small practice goal
After a move, check what changed. Decide which rule explains the new state before acting again. Use the example to check your reasoning.
Your objective
Checkmate the opposing king. An attractive position is not enough unless the goal is met. Start with a deliberate move.
A walkthrough of the rules
- 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.
Using the playing area
Tap a piece and target; choose a promotion piece when needed. A careful first action helps you become familiar with the layout. Read the example below alongside these instructions.
A useful example
Castling cannot pass through an attacked square. Focus on why the action is allowed, not only its outcome. Look for the relevant detail.
An important reminder
The computer is a small search opponent, not a rated engine. A different version of the game may use a different rule. Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board.
