Tidak ada sistem tiket, tidak ada chatbot, dan tidak ada pusat bantuan dengan empat ratus artikel. Yang ada adalah satu alamat surel dan satu daftar kerusakan, dan keduanya bermuara pada orang yang menulis aplikasi ini.

Untuk semua yang Anda lebih suka terbuka — dan untuk semua yang perlu ditemukan orang lain nanti, yang berlaku bagi sebagian besar laporan kesalahan.
Kalau sebuah soal keliru
Kirim empat hal, dan pemeriksaannya memakan waktu satu menit.
- FEN yang tampil di layar soal — tekan lama untuk menyalinnya.
- Langkah yang Anda mainkan, dan langkah yang disebut benar oleh aplikasi.
- Anda sedang berada di mode yang mana.
- Versi aplikasi, dari layar informasi.
Soal sesekali bertentangan dengan pencarian yang lebih dalam, dan pertentangan itu menumpuk pada posisi panjang, tenang, berperingkat tinggi yang inti persoalannya terletak lebih dalam daripada jangkauan pemeriksaan. Itu batas pemeriksaan, bukan kesalahan soal — tetapi ada gunanya tahu yang mana saja, dan satu-satunya cara mengetahuinya adalah bila Anda memberi tahu.
Pertanyaan
Cukup sering ditanyakan sampai perlu ditulis.
- Does it need an internet connection?
- No. The engine, the puzzles and your progress are all on the device. The single exception is online play, which needs Game Center to reach the other person.
- Is there an account?
- There is none to create. Your ratings and history live in the app’s own container on your device, and deleting the app deletes them.
- What is free?
- Playing is free and stays free — against the engine, against a person over Game Center, and the nine hundred games in Watch — all unlimited. On top of that a free account gets five a day of each kind of training: five tactics puzzles, five Rush runs, five positional exercises, five endgame drills and five games to judge. The allowance resets at nine in the morning, local time.
- Why is there no advertising?
- Partly taste and partly licence. The app links two engines — Stockfish under the GPLv3 and Reckless under the AGPLv3 — and compiling a proprietary advertising SDK into the same binary would make the combined work undistributable under either. Selling the app is fine; copyleft has never forbidden charging. Bolting a closed SDK onto it is not.
- Are my puzzle ratings the same as a FIDE rating?
- No, and they run several hundred points higher. They measure progress against yourself, not strength against a field.
- Where do the puzzles come from?
- Most are from the Lichess puzzle database, released into the public domain under CC0, carrying ratings calibrated against millions of real solving attempts. The rest were mined locally by having Stockfish play itself and keeping only positions where one move is far better than every alternative.
- Can I see the source code?
- Yes. The app carries the GNU Affero General Public License version 3 — the terms Reckless brings with it, which the GPLv3 of Stockfish permits combining with — and the complete corresponding source is published on GitHub.
- Which engine am I playing?
- Whichever you chose in Settings. Stockfish and Reckless are both compiled into the app, and one of them plays, grades and labels everything. They are not equivalent: Stockfish can be asked to play anywhere from about 1400 to full strength, while Reckless has no strength limiter and plays at full strength or not at all.
