Reporting a puzzle

Tell us the puzzle number and whether it was Easy or Hard (both are in your share result), and what looked wrong. Every puzzle is meant to be fair on a phone screen, so an unfair one is a bug we'll fix.

Privacy questions

For anything about your data or advertising cookies, read the privacy policy first, then email us if your question isn't answered there.

Pictures

If you believe a picture on FiveDiffs shouldn't be here, email us with the puzzle number and we'll look at it promptly.
