HollyWood Poker, 500% Bonus, whats the catch, I dont understand

[DontRaisePlz]

I am into poker rather for a hobby base rather than profit base, but still, I still have to respect money. There is this offer on Hollywood Poker, "500%", hm its not like I am gonna cash out, what is the BIG CATCH about this 500% bonus, if it is something like playing 1000 rake pots, its cool. Well my question is: 500%, what's the catch!?

I am thinking of depositing 200 dollars, so does that mean I get 1000?

Bonus Option #1:
500% up to $1,000 ($200 deposit required for max bonus)
Must enter code 'HP1000' for the sign-up bonus.
Bonus cleared at 15x the bonus in points.
Bonus expires after 60 days
