Support
Stuck, found a bug, or a sum we got wrong? We'd love to hear from you.
Email us: support@ohmysum.games
Found a bug? In the game, open Settings and tap Report a problem. It starts an email to us with the app version, your phone model and the level you're on already filled in, so we can find it faster. Just add what happened.
It helps if you include your phone model, the app version (at the bottom of the game's Settings) and, for level problems, the level number. A screenshot is always welcome. We usually reply within a few days.
Common questions
I bought coins but didn't get them.
Make sure you're online and reopen the game: it checks for purchases it hasn't delivered yet each time it starts. If they still don't appear, email us with the order number from your Google Play receipt (it starts with "GPA.") and we'll sort it out.
How do I get a refund?
Purchases are made through Google Play, so refunds go through Google. In the Play Store app, open your profile, then Payments & subscriptions → Budget & history, pick the purchase and choose to request a refund. Or see Google's refund help page.
I got a new phone. How do I move my progress?
Sign in on your old phone first: open Settings in the game and tap Sign in to link Google Play Games. Your progress and coins are then saved to your account. On the new phone, install the game and sign in with the same Google Play Games profile, and your progress comes back. If the new phone already has some progress of its own, the game asks which one to keep.
If you never signed in, your progress is only on the old phone. Setting up the new phone from a Google backup of your old one sometimes brings it across.
Why didn't my path count?
A path counts when its digits make the target shown above the board: add them on a + level, multiply them on a × level. A wild star stands for whichever digit makes the target. If you're sure a path should have counted, email us with a screenshot and we'll look into it.
How do I get more lives?
Lives refill by themselves over time. Winning a level never costs a life, and the first 20 levels never cost one at all. You can also buy a refill with coins in the shop.
Does the game have ads?
No, and it never will. The game is free to finish, and coins are the only thing for sale.
Does it work offline?
Yes. You only need a connection to buy coins.
Does the game collect stats about how I play?
Only if you say yes. The first time you play, the game asks "Share gameplay stats?". If you tap Share stats, it sends us stats like which levels you win or lose and the digits of each hit, tagged with a random ID, never your name. We only use them to make the levels better, and we never sell them. Change your mind any time with the "Share gameplay stats" switch in Settings. See our Privacy Policy for the details.
How do I delete my account?
In the game, open Settings → Manage → Delete my account. See how to delete your data for everything else, including what to do if the game isn't installed any more.
Is there an iPhone version?
It's coming soon. Keep an eye on our website.
