Because I suck balls at them, that's why.

I thought, hey this might be fun so I decided to buy it. I played two rounds just now.
Score from Trying to Win = 5,345
Score from Randomly Switching Tiles as Fast as I Can = 11,0375
WTF? Then I look on my friendslist, and some of your cockbags already have like 150,000 points or some crap. Man, I blow at this game. I can't think fast enough to make flushes or or any good hands. I just try to get by on 3s and 4s of a kind. When I do try to set up something better, by the time I do, all the cards are already at the top. If I could lock the game in at Speed 1 I'd probably be alright, but when it gets up to 10, I get my butt kicked. Are there any secrets besides just play it a whole lot and try to get better?
