Hey, this is UmaiKeiki, a very lazy mahjong player -- although I'm often in the company of some real addicts. They've scoured the internet for anything and everything related to Mahjong, and found some really outrageous ideas. Are the tiles given by Tenhou really random? Is a hanchan really the same length as two tonpuusen? Questions like these, while not exactly about "luck" and the "flow of the game", are a bit reminiscent of "occult" Mahjong, which is essentially the belief that random events in Mahjong are not really random.
Now there's nothing terribly wrong with Occult Mahjong in that it can be a convenient way to explain away some minor issues -- such as that awful losing streak you just had, or some secret technique you don't want to share with everyone. However, it sure would be fun to test some of these claims against the mathematics of probability and statistics! Today we shall do exactly this, and see how well they stand up.
