ok kitty nailed every point!!!
I used to play a freeroll at a bar. The bar wanted to play cash but they couldnt because you can get into a lot of trouble.So what they did was have an envelope and you paid 10 bucks (if you wanted too) and the last person who was in the envelope and still playing in the tourney would win all the money.
it was good b/c i always lasted long but it ran into problems b/c people actually playing the freerolls screwed it up. becuase of bad play!!!
