What the game asks you to do
Checkmate the opposing king. Read that aim before choosing your first action. The example below illustrates a decision.
How a round unfolds
- 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.
Input guidance
Tap a piece and target; choose a promotion piece when needed. Use the control method described here for this activity. Avoid pressing the same control repeatedly while a move is being processed.
Put the rules into context
Castling cannot pass through an attacked square. Apply the same reasoning to the position in your own round. Consider the next action carefully.
Watch out for this
The computer is a small search opponent, not a rated engine. Take a moment to reassess the position before continuing. After a move, check what changed. Decide which rule explains the new state before acting again.
