Actually I am pretty good at those machines (the few still in existance). The secret of course is to wait until some one else leaves the machine all set up for you. I normally play only the $.25 machines since the $1 tokens seem to stack more easily. There are normally some basket ball type hoops that will pay off 10-40 coins if hit. Imagine my surprise last year at the convention when I stuck my only $1 token in the machine by the Trops escalator and out came $20 from hitting the hoop. Take the money and run.
