Invaders of the Planet Moolah.. UGH.. that repetitive sound when someone is in the bonus.. and it is normally set with the volume so HIGH. I have moved from a machine I enjoyed because my nerves couldn't handle that machine. I am not sad they are slowing going away .

DH plays Caveman Keno once in a while.. I am used to it. .so the sound doesn't annoy me.. but I totally understand how it can be GRATING!
