This is a online Chinese mahjong game:
1. Requires very little amount of network flow: consumes only hundreds of bytes per round.
2. All calculations are performed on the server, so cheating is nearly impossible.
3. As secure as online banking.
4. At this moment the only supported mahjong rule is 卡五星, but other rules like 武汉麻将/四川麻将 will be added soon.
5. Incoming phone call or other events will not take player offline(unless the player deliberately quits the game).
6. Screenshot is prohibited when game is running.
7. Use of this software at your own risk.
