- Is Stackt free?
- Yes. Stackt is free to play with ads between rounds. A one-time Remove Ads purchase is available in the Shop if you'd rather play ad-free — it's a single payment, not a subscription.
- I bought Remove Ads but still see ads / it's not restoring on a new device
- Open the Shop and tap Restore Purchases — Apple re-links it to your Apple ID automatically. If that doesn't fix it, email us the approximate purchase date and we'll sort it out.
- How does the Daily Challenge work?
- Everyone gets the same puzzle each day. Complete it to keep your streak alive — a new one unlocks at midnight local time.
- Can I play offline?
- Yes, the puzzle itself needs no connection. Ads simply won't load without one.
- How do I delete my data?
- Everything lives on your device only — deleting the app deletes your progress. There's no account or server-side data to remove.
