Frequently Asked Questions

I changed devices and my records are gone

Records created while not signed in are stored only on that device. If you sign in with Google or Apple, your records, cubes, and currency are saved to your account and carry over to other devices. Please sign in before changing devices.

I paid for Cube Crystals but didn't receive them

Payments are processed by the App Store and Google Play, and items are delivered after the receipt is verified. If your network is unstable, delivery may be delayed for a short time; it will be applied automatically when you restart the app. If you still haven't received them, please email us at the address above with your payment receipt (order number). You will not be charged twice.

I want a refund

Refunds for in-app purchases are handled by the store where you made the purchase. We cannot process them for you in the app.

• App Store: Go to reportaproblem.apple.com, select the purchase, and request a refund
• Google Play: Play Store → Payments & subscriptions → Order history → Request a refund

Currency granted through a refunded purchase may be reclaimed, and repeated refunds may be grounds for restricting use.

A minor made a purchase without a guardian's consent

You can request cancellation under the store's refund policy. Please follow the refund steps above, and let us know at the email above as well if needed.

To control purchases in advance, please use the store's parental features. On the App Store, Ask to Buy in Family Sharing lets a guardian approve a child's purchases, and on Google Play, purchase approvals and authentication settings provide the same control. You can also block in-app purchases entirely with the device's own Screen Time or Digital Wellbeing settings.

Can cube boxes (draws) only be opened by paying?

No. You can also open them with cube shards earned from daily missions and free opening tickets earned by watching ads. The odds for each rarity and the pity system (a Legend is guaranteed at 100 openings) can always be checked on the draw screen in the app.

I want to delete my account and data

You can delete it yourself in the app under Settings → Delete account. When you do, your profile, records, and currency stored on our servers are all destroyed and cannot be recovered. If you cannot access the app, please send a request to the email above along with the email address of the account you signed in with (Google or Apple). If you chose "Hide My Email" when signing in with Apple, please tell us the address ending in privaterelay.appleid.com.

I don't see any ads

This app has only rewarded ads. They play only when you choose to watch them, and there are no forced interstitial or banner ads. You can receive up to one free opening ticket per day.

My records don't appear in the rankings

You need to sign in to appear in the rankings. Also, the Daily Contest opens with a new scramble every day, and records submitted after the deadline count toward the next round.

I want to report or block a player with an inappropriate nickname

In rankings, your friend list, and similar places, tap the ⋯ button next to the nickname and choose Report or Block. You need to be logged in to report or block players.

• Report: Choose a reason (Inappropriate nickname, Impersonation, or Something else) to let the Operator know. We usually review reports within 2–3 business days and take action, such as resetting the nickname, when needed. We don’t tell the other player that you reported them.
• Block: Neither of you can send friend requests or match invites, and you’ll no longer be friends. Their nickname is hidden in rankings.

You can unblock anytime in Settings → Blocked users.
