Don't feel bad, I've had my "Gladiator" machine almost 2 years and it still does things I don't understand. I thought it was going to be permanatly flipped out when I got all 9 gold fleour de leis (french pointy 3 leaf clover things) and all 9 drums went yellow after all the reals went respinning after a red/blue/purple almost match. I too don't understand the 4 red LED's in a square pattern with the XO XO pattern in the lens. Most of the time I have 2 or 3 lit. Is there a FAQ?
