If you are the first to win in all 14 levels, you get additional 25BTC. It doesn't matter how you do it or how many times you try. Even the order of the tournaments you win doesn't matter.
Fair enough.
I expect it would be hard to find enough people to play at some of the higher levels though. The highest level is a 25,000 chip buyin I think, which is about $700 or so isn't it?
The other thing I was wondering about was what the red, green, and blue tournaments were about. Do I 'only' have to win all the blue ones to get the 25BTC prize?
