3 Up 3 Down — Support
Answers to common questions, and a human if you need one.
How do I play?
Full rules are built into the app — tap the ⓘ button on any screen. The short version: play a card equal or higher than the pile, shed your hand, then your face-up cards, then your face-down cards blind. First to shed all nine wins.
- 2 resets the pile — anything can follow it.
- 8 locks the pile — the next card must be 8 or lower.
- 10 burns the pile and you go again.
- Joker is a wild bomb — or declare it as any value.
- Four of a kind on the pile is a mega bomb — instant burn.
Nearby Multiplayer isn't finding my friend
- Both devices need Wi-Fi or Bluetooth on, ideally on the same Wi-Fi network.
- When iOS asks for Local Network permission, tap Allow — this is required for device-to-device play. You can check it in Settings → Privacy & Security → Local Network.
- The joiner must type the host's 4-letter code exactly.
- Still stuck? Force-quit the app on both devices and try again — and email us.
Does the app collect my data?
No. Nothing. See our privacy policy — it is one paragraph long, because there is nothing to disclose.
