What the game asks you to do
Checkmate the opposing king. Keep that objective in view throughout the round. Follow this game’s rules rather than another version’s.
Follow these playing steps
- 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. Return to the rules if the result is unexpected.
One way to understand the rules
Castling cannot pass through an attacked square. Compare this with the rule that governs the move. Keep the controls nearby.
A useful caution
The computer is a small search opponent, not a rated engine. Take a moment to reassess the position before continuing. 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.
