I just tried this too, for Planetluck and Starluck. They both work. I got shady customer support though. When I first downloaded with both they only gave me $10 dollars. Starlucks online support was cooperative and they credited me with 35! Planetluck, however, said this bonus was for new members only (not true), so I kept contacting support and they finally gave me the bonus. This is the easiest bonus money you'll ever make.

I'm heading to PartyBingo and Aceclub to check things out...
