Yes, my Dh and I played about $1500 each in those craps "bubble" machines. My express comps were $11.00 after that. Eta: I'm not sure if there is a sign on them stating no points though.
interesting!! now i finally understand why you can insert your card but cant get regular comps--you get express comps on the machine!! really cool
oh yeah btw, the bubble craps does not generate for people regular comps. i think it reads so on the machine.
