Common questions

A few quick answers

How do I back up or move my progress?

Your progress is saved on your device. Open Progress, choose Export, and save the JSON backup somewhere safe. To restore it or move it to another device, open Progress → Import and select the file.

Imports validate solutions and keep the shorter one when both devices have solved a puzzle.

Do I need an internet connection?

The ordinary puzzle game works offline. Only the optional AI Battlefield connects to the AI providers you configure. You can play the puzzles without setting up an AI provider.

Why is my AI provider request failing?

Check the provider’s API key, endpoint, model availability, account balance and usage limits. Your device also needs to be able to reach the provider over the network.

If you still need help, include the provider and model names and the error message. Never send your API key.

Can AI Battlefield requests cost money?

AI Battlefield uses your own provider account and API key. The provider may charge you for requests according to its pricing. The app does not supply shared credits.

Optional time and token limits help control a match, but the provider’s billing records determine the charges.

How do I remove a stored API key?

In AI Battlefield, open AI Providers (Models on iPhone), select the provider and choose Remove provider. This deletes its configuration and stored Keychain key.

Existing match histories remain on your device.

Which languages does the app support?

English, Simplified Chinese and Japanese. The app follows your device or per-app language setting and uses English for other languages.
