Need help with the loop?
If something in Fathom is not working, or if you need help with a purchase, progress, or account request, contact support.
Frequently asked questions
Can I play offline?
Yes. The launch puzzle bank is bundled with the app, so owned puzzle content is playable offline. You need a connection for purchase, restore, optional sign-in, and progress sync.
Do I need an account?
No. Fathom starts with an anonymous Firebase player. Apple or Google sign-in is optional in Settings if you want account recovery or cross-device sync.
How do hints and X marks work?
Tap an edge to cycle through empty, drawn, and X-marked. X marks are your notes for impossible paths. Hints point toward the next useful deduction without adding pressure.
How do I reset progress?
Open Settings and choose Reset progress. This clears local solved puzzles, in-progress boards, and settings on the device.
How do I delete account data?
If you linked Apple or Google sign-in, open Settings and choose Delete account. See the delete account and data page for details and an email alternative.
