Backgammon Support
Arcane Void LLC · support and suggestions: backgammon [at] arcanevoid [dot] com
Write to backgammon [at] arcanevoid [dot] com. A person reads every message. Tell us your device, your Android version, which edition you have, and what happened — we answer faster when we do not have to ask.
The dice are wrong
They are checkable, so check them. Open the dice sheet from the plaque on the home screen or in a game. Before the game it shows the seal and the commitment. When the game ends it reveals the seed, recomputes every roll of that game, and tells you whether all of them, the seal and the commitment match. To check without trusting the app, paste the revealed seed and salt into the verifier on this site, or run verify_dice.py yourself.
A run of doubles against you is not evidence of anything. Over a few hundred rolls, one double in six and about eight pips a roll is what a fair die gives, and swings either way are ordinary. If the ledger ever reports a roll that does not match the seed, keep that game record and send it to us: that is a defect and we want it.
I bought Pro and still see advertisements
Backgammon and Backgammon Pro are two separate applications. Buying Pro installs a second application, without advertising; the free one stays on your device until you remove it. Uninstall the free edition once your games matter to you no longer, and use Pro.
My games and statistics did not come across to Pro
They do not. Android keeps each application's data to itself, and we do not copy it between the two. Your record in the free edition stays there for as long as it stays installed.
I changed device, or reinstalled
Backgammon Pro is tied to the Google account that bought it. Sign in with that account on the new device and install it from Google Play; there is nothing to restore and no code to enter. Saved games and statistics live on the device, so they travel only if Android's own backup restored them.
Deleting everything the game stored
Uninstall it, or use Android's Settings → Apps → Backgammon → Storage → Clear data. Nothing is held anywhere else. The privacy policy lists exactly what is stored.
An advertisement was deceptive or unsuitable
Send us a screenshot. Google selects the advertisements, so we cannot block one advertiser on our own, but we do report them and we can change where advertisements are allowed to appear.
Reporting a defect
Useful reports say what you did, what happened, and what you expected. For a wrong move, a wrong score or a wrong analysis, the game record is worth more than a description of it: open the dice sheet and copy the seed and salt line, and tell us the roll number where it went wrong. That lets us replay your exact game.
Asking for something
Feature requests are read and kept. So is a message telling us that a control is too small, that a colour is hard to read, or that a screen reader does not say the right thing — accessibility reports are treated as defects, not as suggestions.
