O.K. - I have had this game less than a week and have been playing the hell out of it. Only matched a few times (UGHHH - guess the luck has not hit yet?).....Anyway, What does the "Chance" button do on the shooter's try? Will it light up when I need to use it or what? Need so help from the gang.....Besides not really hitting anything yet, It's very addicting and I love this machine !!!! Thanks...

Joe
