Due to the free weekend, I have 36 bucks.

If I understand it right, If I deposit 20 bucks I will be bumped up to 56 bucks, then I have to play 6 more games, and then I can withdraw 50 bucks*,

Is my understanding correct, or is there something missing. Some other fees, or some time delay.

*[being impossible to lose more then 6 bucks in 6 games if you play for a buck]
