The file on this page is Numbers & Letters 1.133, 36.89 MB, and it installs on Android 13 and newer.
We compared the signing certificate of this build with the certificate recorded the first time fr.pierre.chiffreslettres entered the site, and published both the file's SHA-256 and the certificate's fingerprint above so you can check the download yourself. That comparison says the file was not repackaged by someone else; it is not a review of what the game does.
The manifest inside the APK declares 12 permissions, none of which cover contacts, location, SMS, the camera or the microphone.
Its licence is GPL-3.0-only. We took this build from F-Droid, and the source for this exact version is linked below.
We do not show a star rating or an install count for this page: we have no measured figure for either, and a number we cannot source is worth less than an empty field.
