Puzzle generation
Puzzle analysis runs locally and can take longer on older devices or complex positions. Keep the app open while a puzzle is being prepared. If an error appears, use the retry control. You do not need a computer or a CloudChess account to play.
Saved progress
Scores and collected styles are stored on this device. Updating the app preserves its local data. Deleting the app removes local progress; avoid deleting it as a troubleshooting step unless you intend to reset it.
Free play and Premium
New players start with a set of free puzzles. After that, free play is supported by ads: every few puzzles you can watch a short ad, or a longer set of ads, to unlock the next batch of puzzles. Because free play relies on ads, it needs an internet connection. Premium (monthly or yearly) removes ads and works fully offline. Reopening a current puzzle, hints and undo never use another puzzle. Open Settings to subscribe, restore purchases, or manage and cancel your subscription. Prices are shown by the App Store in your local currency.
