Frequently Asked Questions
How does the daily puzzle work?
Everyone receives the same mystery animal each day. Search for an animal by its common name, Latin name, or a supported alternate name, then select a matching result to make a guess. Incorrect guesses reveal the closest taxonomic group you share with the mystery animal, helping you narrow it down.
When does a new puzzle arrive?
A new puzzle becomes available at midnight Pacific time (PST/PDT). Your completed puzzle and its result remain available to review until the next reset.
Why can't I submit an animal name?
Common Branch accepts only animals in its curated list. Try choosing one of the suggested results, checking the spelling, or searching by the animal's Latin name. If an animal or name you expected is missing, please send us a note.
How do hints work?
After you have made a guess, you can spend three guesses to reveal the next deeper taxonomic rank on the mystery animal's path. Hints can reveal as far as Genus, but never the answer's Species.
Why is the puzzle unavailable?
Common Branch needs an internet connection to load and submit the daily puzzle. Check your connection, then choose Retry. A guess or hint is not spent unless the app confirms it successfully.
Can I get a reminder when a new puzzle is ready?
Yes. In Settings, turn on Notify me when puzzles go live. Notifications are optional; you can change permission later in your iPhone's Settings app.
How is my progress saved?
The app does not require an account. It uses an anonymous credential stored in your iPhone Keychain to restore your progress when it is still available. If that credential is lost, such as after a device reset, your earlier progress may not be recoverable.
Does deleting the app delete my progress or data?
No. Deleting the app does not by itself delete server-side progress. To request access to or deletion of your information, email colin@arcworkstech.com. Including the anonymous player identifier shown in the app can help us locate the correct record.
Is there a subscription or are there in-app purchases?
No. Common Branch is free at launch and has no subscriptions, in-app purchases, or advertising.
How do I report a content problem or app bug?
Use Report an Issue in Settings for a quick, anonymous one-way report. For support, privacy requests, or a response, email colin@arcworkstech.com instead.
How do I get help with privacy or a child's information?
For privacy questions, or to request access to or deletion of information, email colin@arcworkstech.com. Parents and guardians should contact us on behalf of children under 13.
