I take anywhere from $100-200 per trip. I play $20 per machine at 4-5 spins. If I get no good winnings or none at all I cash out and move on. I've won several thousand dollars in the past 9-10 months. I once won a JP of $3260, JP of $750, $1000 Fort Knox nickel machine, $900 playing deal or no deal, 671 playing Garfield nickel machine. A total of about $2000 playing various nickel machines and $308 at a quarter machine.
I'm hoping for the 3+mill Megabucks
