A hand with your ink.

Slipglyph is made by Robert Jakobsson. For a bug, purchase issue, privacy request, or a very strange drawing, get in touch.

My ink goes the wrong way

That is the game. Mirror reverses left and right. Quarter turn makes an upward finger movement draw right. Upside down reverses both axes. Touch anywhere on the board; your ink starts at the ring. Follow the dots in one continuous stroke, then lift your finger to finish.

How does the score work?

Accuracy measures how closely your ink follows the target. Coverage measures how much of the target you traced. Both matter, and excessive scribbling reduces the score. Your challenge result is the average of its three rounds. Try the warm-up from How to play before the daily challenge.

When is the next daily challenge?

At midnight UTC. Players on the same app version get the same daily shapes and rules. You can replay today’s challenge as often as you like. The app keeps both your first attempt and your best score while those attempts remain in your local collection.

Studio is missing after I changed phones

Open Studio and choose Restore Purchases while connected to the internet and signed in to the same Apple Account. If Apple approved a refund, the extra inks will no longer be unlocked. Family Sharing is not supported. For an unresolved issue, email support; for a refund request, visit Apple’s Report a Problem.

The shop says “coming soon”

Studio is available only when Apple returns its product listing for your storefront. If it is unavailable, all free modes remain playable. Use Check availability later. In a development build, real purchases require the product to be configured in App Store Connect.

Can I play offline?

Yes. Daily shapes are generated on your phone, and the collection is stored locally. Apple purchases, restoration, website links, and online sharing destinations need a connection.

How do I delete my drawings?

Settings → Erase drawings & progress removes the local collection and resets preferences. There is no account to close. This does not delete your Apple purchase or copies in device backups. See Privacy & GDPR for details and your rights.

Accessibility

Menus have VoiceOver labels and the app has a guided warm-up. Haptics are optional, no sound is required, and there is no flashing content. Drawing is a visual, continuous-touch activity and currently requires sight and fine motor control. The browser preview also offers keyboard controls: Space to begin, arrows to draw, Enter to finish.
