FAQ (Frequently Asked Questions)

1. Can’t join a room after entering the room ID in online matches?

Rooms are located by mahjong rule + room ID. Ensure your selected rule matches the host’s.

2. Others can’t find my created room via search?

Set room visibility to Public during creation for searchability. Private rooms can only be joined via rule + room ID.

3. Can I rejoin after disconnection?

Regular players may reconnect and resume. If the host disconnects, the match ends immediately; hosts need stable internet.

4. Can I rotate the camera to view others’ tiles?

No. Opponents’ tiles are private and not loaded on your client during live games. You may view them only in replays.

5. Will replay files fill up my storage?

Each replay is roughly 100KB. You can delete files manually on the replay page anytime.

6. Where to get the mobile version?

Mobile builds are under submission. Stay tuned.

7. Will more game variants be added later?

We will add new rules based on player feedback. As a solo-developed project, bug fixes take priority for now.

8. How do I edit my profile info?

Click your avatar in the top-left corner on the main menu to edit. Display names can’t be changed mid-online matches: Steam logins use your Steam display name, EOS logins use your Epic display name.
