Mahjong

[Talking Poker]

Is this game extremely difficult to beat, or is it just me?

I feel like I'm playing it well and making the correct strategy decisions as I go along, but I end up screwing myself somehow the majority of the time.

Generally speaking, what's more valuable - Clearing tiles from higher rows that have tiles under them, or clearing bottom level tiles on rows that are much wider? Originally, I thought it was the former, then I thought it must be the latter, and now I think it depends how far along you are in the game.

But I really have no idea. Any Mahjong experts out there?
