about
- description
- Chess Puzzles is an offline tactics trainer built from real positions in the Lichess puzzle database. Find the best move, follow the tactical line, and improve at your own pace. - **Clear goals.** Each puzzle tells you what to find, such as checkmate in two. - **Three difficulty bands.** Choose Easy, Medium, or Hard puzzles. - **Useful hints.** Reveal the move to play when you need a nudge. - **Opening practice.** Learn twenty openings move by move, then practise them from memory against selected replies. - **Saved progress.** Track solved puzzles, puzzles solved without a hint, and streaks on your device. - **Light and dark themes.** Use the board that suits your screen. - **Fully offline.** Every puzzle is bundled with the app. The app needs no account. It never asks you for a permission and cannot use the internet. It contains no ads, analytics, or tracking. Puzzles come from the Lichess Open Database under CC0 1.0, and opening names from Lichess's opening list, also CC0 1.0.
