Mahjong For Dummies?

[TattersailNightwish]

You need to do a "quest" first. Go to the room with the main counter where you can claim the prizes, there should be a woman sitting at a table with a quest-marker in the back of the room (should be shown on your map. It's 4.8/something). She will send you to another woman, she's in the manderville lounge. There are also the playing tables (after you have talked to her).

I found her, and unlocked the game.
Thanks so much!
