The essentials of playing Chess Online
Make Chess Online your next activity in the game library. Checkmate the opposing king. Keep the game area visible while you use its controls. 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 focus for your next round
Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board. Notice the feedback after each input.
What counts as success
Checkmate the opposing king. The feedback beside the game helps you follow the round. Take a moment to understand the current position.

Your inputs
Tap a piece and target; choose a promotion piece when needed. Keep the playing area visible while using these controls. Check any mode label before starting.
Learn from a sample situation
Castling cannot pass through an attacked square. Compare this with the rule that governs the move. Verify the rule before continuing.
Keep this in mind
The computer is a small search opponent, not a rated engine. Compare the situation with the worked example. After a move, check what changed. Decide which rule explains the new state before acting again.
