Report a problem
Tell us your Android version, device model, app version, what you did, what happened and what you expected. Remove personal information from attachments. Never post a tester email list or private feedback in a public repository.
Install or update the test APK
Requires Android 7.0 or later and an ARM64 device. Download an APK from the app page and open it with Android's installer. Allow installation from your chosen browser only if you trust this development build. Install over a compatible development-signed version to preserve progress. Version 1.0.1 uses APK version code 2002. English, Romanian and Spanish are available in Settings.
Download the Google variant for a Google-services phone or the Huawei variant for HMS testing. Both variants share one application ID and replace each other, rather than installing side by side. Commercial purchase restoration is store-specific. If Android reports a signing conflict, contact support before uninstalling: uninstalling removes private app data. The later production certificate may require a fresh installation. Do not disable Play Protect or other security protections.
Testing checklist
- Play Classic and collect a category sigil.
- Try Practice, Speed, Survival and the once-daily challenge.
- Switch all three languages and light/dark themes; restart and verify local progress.
- Use airplane mode and verify questions and core gameplay remain available.
- Open Settings online and offline; verify absent or failed ads leave no banner space and gameplay remains available.
- Check advertising choices, background/resume and store-specific restore errors. Real store/HMS advertising and payment validation remain pending.
Data removal
Local records remain until deleted. Resetting game progress preserves purchase proof and the one-time bonus marker. Clearing app storage or uninstalling removes local records; Android cloud backup is disabled. There is no developer server copy of gameplay. Store transaction and advertising records are subject to their respective providers' retention policies and controls. Clearing local data does not refund purchases or delete provider records.
Joining a test
Testing invitations and opt-in links will be supplied once a Google Play testing track is available. This page does not enroll you in a test. Report your experience honestly; no positive review is required.
