Wild Jack signup bonus - Someone please clarify

[jmrogers7]

Wild Jack is having a 25% up to $100 signup bonus. 5x raked hands. A raked hand is $0.25 or better. Sounds like a standard Prima.

However, they also have a clause in there that the bonus must be played through at least once before withdrawing.

Does this simply mean that after I play my 500 raked hands that I must then wager another $100 before I can withdraw?

Thanks!
