Common questions

How do I play?

Slide the coloured tiles until the 3×3 area in the middle of the board matches the small target pattern. Tap “How to Play” on the home screen for the full rules.

How do I play with a friend?

Choose Duel (two players) or Triple Race (three), create a room, and share the link or let your friend scan the QR code. No account needed.

My friend can't join my room.

Everyone needs an internet connection, and the room code is only valid while the room is open. If the code was typed by hand, check for confusable characters, or use the QR code instead.

Why doesn't my time appear on the leaderboard?

Scores are only posted when you have entered a name. You can add one on the home screen, or on the win screen right after solving a puzzle.

Can I play without an internet connection?

Yes — single player works fully offline. Duel, Triple Race and the leaderboard need a connection.

I can't hear any sound.

Check that game sounds and music are switched on in Settings (⚙️ on the home screen), and that your device isn't muted.

How do I delete my data?

Uninstalling the app removes everything stored on your device. To remove a leaderboard entry, email us — see the address above. Full details are in the privacy policy.
