Frequently Asked Questions
Do I have to pay again for a second device?
No. Use Restore Purchases on the purchase menu on your new device — it works on both iOS and Android. The App Store and Google Play are separate stores, so purchases don’t transfer between them; contact us if you play on both.
Why is the hand I’m playing disappearing?
- When you call a tile and expose, hands that can no longer match are removed — including all concealed hands.
- Hands are sorted by the closest matching hand, so the list reorders as you play. To lock the sorting, use the Game Menu on iOS or Android.
What is the return or cancel policy?
Cancel subscriptions or get a refund anytime, for any reason. See the Subscriptions page for how to cancel or request a refund on your platform.
Is 113579 1111 1111 wrong?
No — the important detail players miss on this hand is that the kongs match the pair. See examples of valid hands on the Tricky Hands page.
