The honest answers.
No account, no ads, no fine print. Here's what people most often want to know.
Do I need an account to play?
No. Fudeto needs no account, no email, and no login. Open the app and the day's puzzle is there. Your streak and progress live on your device — not on a server somewhere.
Can I move my progress to a new phone?
Yes — with Fudeto Pro. Pro keeps a private backup of your progress (streak, solve history, rating, stars), tied to your store account. On a new device, tap Restore Purchases and both your Pro access and your progress come back — no account, no login. Without Pro, your progress simply stays on the device.
Are there any ads?
None — for everyone, free or Pro. No banners, no interstitials between puzzles, and no watch-an-ad-for-a-reward mechanics. Fudeto is paid for by the people who choose Pro, not by your attention.
Can I play offline?
Yes. Once the day's puzzle has loaded, you can solve it with no connection at all. The web core is about 35 KB and carries no trackers, so it stays light and works quietly on a train or a plane.
Is every puzzle actually solvable?
Always. Each board is constructed to contain an Euler trail — the single-stroke path Leonhard Euler described in 1736 when he studied the seven bridges of Königsberg. A solution is mathematically guaranteed to exist. Your job is simply to find it.
How do I cancel Fudeto Pro?
Fudeto Pro is billed through your app store, so you cancel it there — and you keep Pro until the current period ends.
iOS: Settings → your name → Subscriptions → Fudeto → Cancel Subscription.
Android: Play Store → Payments & subscriptions → Subscriptions → Fudeto → Cancel.
