Bill, I have noticed that whenever I play just one quarter there enevitably is a winner on lines two and three. I gave up trying to out rationalize the randomizing of the computer chips. I found the same theory doesn't work on video poker machines. Many royal flushs have been flushed (pardon the expression) when one does not play five credits for the maximum pay out. If you do develop a system I would sell it to the casios or keep it to myself; but definitely not post it on a bulletin board. Thanks and Take Care Bro. Terrible Terrence
