Ok, I had all of this great, witty advice for this game, but ironically, as I was typing the end of a huge post, and adding the tip to not play netwinner in FireFox due to occasional browser crashes, the NetWinner tab I had caused FF to crash, and now I'm too lazy to retype it. One thing I wanted to mention was that I first read about NetWinner at your great blog:

And to summarize the tips (not quite as funny):
You can enter numbers in with your keyboard.
You don't have to click the "play again" button, just wait a second
You can click WIN when the last ball is being chosen under quick pick mode and it will start checking the numbers as soon as the quick pick is done.
You can sign affiliates up under you, and, like Blingo, you will benefit from their winnings.
Don't play this in FireFox, your browser will crash.
So, do you guys use Quick Pick, or do you choose your own numbers? Flash programs run slow on both of my computers for some reason, so I just click quick pick and multitask while it's picking the numbers.
