Support

Email support@moondoku.com about anything — a bug, a puzzle that looks wrong, your account, or a refund. We aim to reply within two business days. If you're writing about an account, send it from the address the account uses, or tell us which address that is.

Before you write

The FAQ covers the questions we're asked most: how hints and difficulty work, what an account gets you, and how the Nightly puzzle is chosen.

Signing in

MoonDoku has no passwords. On the web you sign in with Apple, with Google, or with a link we email you; in the iOS app it's Sign in with Apple or Google; on Steam it's a code sent to your email. If a link or code doesn't arrive, check your spam folder first — and if it still hasn't, write to us and we'll get you in.

You don't need an account to play. Tonight's Nightly is free for everyone, everywhere, with or without one. On Steam the rest of the puzzles come with the app; on the web and in the iOS app, endless play is what the full game unlocks. An account adds your streak, your sky, achievements, and syncing between devices.

Deleting your account or data

You can delete your account yourself, on the web under Account → Security and in the iOS app under Account, then Delete account. It removes the account and everything attached to it: sessions, scores, streaks, achievements, leaderboard entries, and the sign-in tokens held by your devices. It cannot be undone, and it isn't reversible by us either.

If you bought the full game at moondoku.com, deleting takes that with it — the unlock lives on the account and can't be moved or restored. Ask for a refund first if that's what you want.

To ask what we hold about you, email support@moondoku.com. The privacy policy sets out what we collect and why.

Purchases and refunds

Bought at moondoku.com? Our refund policy is 30 days, no questions asked. Bought on the App Store or on Steam? Apple and Valve handle those refunds themselves — for iOS use reportaproblem.apple.com, for Steam use Steam Support. Purchases don't carry between the web, iOS, and Steam versions: each one is bought where it's played.

Reporting a puzzle

Every puzzle ships with exactly one solution and is checked to be solvable by logic alone — no guessing required at any difficulty. If one ever seems otherwise, tell us the difficulty and roughly when you played it, and a screenshot of the board if you have one; that's enough for us to find the exact puzzle you were given.
