"Real Mah Jong for Skilled Players"
If you're up to speed, you can play against the computer or against other players around the world. It's real Mah Jong, not the solitaire tile-matching computer game.
If you're a beginner at Mah Jong, this is NOT the one for you to learn on. Even against the computer, play is very fast and you should perhaps already know how to play the game before diving in. Not for the faint of heart.
Looking to LEARN to play the actual ancient game of Mah Jong? (Not the computer solitaire version, but the four-player ancient board game.) Look elsewhere. This is for experienced players who already know the ins and outs of the game. If that's you, you might love it. Allows online play against other users, or practice against the computer.
