Frequently Asked Questions

How do I restore my Parlor Patron purchase on another device?

Open the game, tap the Settings (Sliders) icon in the top-right corner of the main lobby, scroll to Parlor Patron Pass, and tap Restore Purchases · 恢復購買 while signed in with the same Apple ID. Once unlocked, Parlor Patron benefits work offline and in Airplane Mode too.

How do I invite friends to a Private Parlor?

Tap MULTIPLAYER on the main screen, choose 2, 3, or 4 human seats, and tap Create 4-Player Parlor (or 2-/3-Player Parlor). Share the invite link via Messages or AirDrop—tapping the link launches straight into your parlor—or have friends enter the 4-digit HK-XXXX room code and tap Join. For remote Wi-Fi play across different locations, make sure all players are signed in to Apple Game Center in device Settings.

Why couldn't I declare a win ("Sik Wu · 食糊") on a 0-Faan hand?

Classic Hong Kong Mahjong defaults to a 3-Faan Minimum (三番起糊). In Quick Play or Private Parlors, you can customize Minimum Faan down to 0 Faan (Chicken Hand · 屁糊) or 1 Faan in Rule Settings, and consult the in-game Faan Guide (?) anytime to view every winning pattern.

Does my World Tour progress sync across iPhone, iPhone Duo, iPad, and Mac?

Yes! Sign in with the same iCloud and Apple Game Center account on each device and your completed cities, Commemorative Seal Passport, and career statistics sync automatically.
