- Drag a white piece (hover shows legal squares); “New game” restarts; auto-saves
- Controls
- Mouse · Touch
- Length
- 3–15 min
Changes and credits
- Changes
- Added a localized title bar, status line and “New game” button, in-page messages instead of alert(), a narrow-screen board and Spare pause/snapshot hooks (PGN saves); AI and board code unchanged. Includes chessboard.js (MIT), chess.js (BSD-2), jQuery (MIT)
