How can we help?

Getting started

1. Choose Campaign, Daily Challenge, or Quick Duel.
2. Start the touch directly on the shooter marble.
3. Slide forward deliberately until the aim indicator arms.
4. Release to launch and clear every target from the ring.

Campaign and Daily Challenge levels are complete only when every target marble has left the ring.

Master Circuit purchase

• Chapters 7 and 8 are one optional permanent purchase.
• Open a locked level in either chapter to see localized App Store pricing.
• Restore Purchases is available on the expansion screen and in Settings.
• Apple processes payment through the Apple ID confirmation sheet.

Thumb Marbles does not receive or store payment-card details.

Troubleshooting

• Confirm that sound and haptics are enabled in Settings.
• Restart the app if a match is interrupted.
• Reinstalling resets local progress, coins, items, and settings.
• A previous Master Circuit purchase can be restored with the same Apple ID.
