If you look on the 'Fish for Cash' page under where you enter the gamecodes, you will see a link 'how to play'; this will give you all the information you need including what booty can be used for.

as far as i am aware you can use them to enter the weekly raffle and to bet on butch pix photos in the weekly competition,i havnt been a member for very long so there might be some other uses that i am unaware of. i hope this helps you.
