Chess Online: how a round works
Take a moment with Chess Online before moving to another game. Checkmate the opposing king. Check the relevant rule before repeating a move. 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.
One thing to notice as you play
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 the game asks you to do
Checkmate the opposing king. Read that aim before choosing your first action. Take a moment to understand the current position.
Start here and follow along
- 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.
Choosing and moving on screen
Tap a piece and target; choose a promotion piece when needed. On a smaller screen, keep the active part of the board within view. Use the visible help when you are unsure of the next input.
Work through an example
Castling cannot pass through an attacked square. Your next round may have a different position, so inspect it before acting. Keep the game’s format in mind.
A mistake to avoid
The computer is a small search opponent, not a rated engine. A different version of the game may use a different rule. Keep the stated aim separate from side details such as animation or appearance. Progress is measured by the game’s own completion or scoring rules.
