1. How to play
From the main screen you can start local two-player play, play the computer, or play online. The Study sheet leads to Lessons, Drill Practice, the Analysis Board, and the Opening Explorer; the bottom navigation covers Puzzles and Ranking.
2. Progress, hints/undos, language, and sync
Your stats, achievements, and puzzle history are saved automatically on your device. Hints and undos can be earned by watching an ad or bought. In Settings you can change language, board theme, piece style, and sound/haptics. Signing in with Apple syncs your progress and purchases across devices.
3. Contacting us about an issue
Put 'Chess' in your email subject, and tell us the app version, your device model and OS version, and the exact steps that led to the issue. For billing/subscription issues, attaching your Apple receipt info helps us respond faster.
