When I go with Michelle we have been using it on dollars and hope to win something, like 3 line pinball or a5 line....i like total meltdown or high voltage for that random respin. When I go with my friend, if he's playing on my card we take the freeplay and each add equal money in with it then play bigger like nickels or max bet on pennies and then split any wins...adding the money makes it last longer and let's us play "big" longer
