Frequently Asked Questions
How do I install the downloaded APK?
Open the APK on your Android device and follow the system prompt to allow installation from your browser or file manager. The current file is a debug build for testing. Confirm that it was downloaded from this website before installing it.
What are the basic rules?
Each puzzle provides four numbers. Use every number exactly once and apply the allowed operations to reach 24. Easy Mode uses addition and subtraction only. Classic Mode uses integer arithmetic, and every division must produce an integer.
Does the game require internet access or an account?
No. Android v1.0.0 works entirely offline, creates no account, and does not upload scores or puzzle history.
Why is there a countdown when I return to the app?
Rush and Battle timers pause while the app is in the background. A three-second countdown resumes the session so switching apps does not affect the match.
How do I clear scores and settings?
Open Settings & Local Records to clear local scores or restore the default sound, haptic, and theme settings. You can also clear the app's storage from Android system settings.
