Questions, bug reports, rules disputes, or a hand you think the Dragon scored wrongly — write to info@okbyus.com and include your device model and what game you were playing.

Quick answers

• Nearby players don't appear: both devices need the app OPEN, WiFi or Bluetooth ON, and Local Network permission allowed (Settings → Privacy → Local Network → Mahj Dragon).
• Fewer than four people? The host can deal any empty seats to Dragon Bots from the table page.
• Mid-game disconnect: a bot covers the seat instantly; reopen the app and you're pulled straight back in.
• The card: Mahj Dragon plays its own original Dragon House Card. It is not affiliated with the National Mah Jongg League and does not reproduce their card.
