Chess Online: a guide for your next round
Open Chess Online, check the instructions and begin a round. 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.
Practice with a purpose
Choose one rule to keep in mind for this round. Apply it consistently rather than guessing what another version might allow. Keep the objective visible.
What counts as success
Checkmate the opposing king. Read that aim before choosing your first action. Follow this game’s rules rather than another version’s.
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.
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.
An example to follow
Castling cannot pass through an attacked square. Apply the same reasoning to the position in your own round. Notice the change in the playing area.
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. Read one step at a time and try it on the playing area. Match the instruction to the control you use.
