Hacking A Crane Game
Position yourself inconspicuously in sight of the claw machine that has the prize you wish to win.
Record each person who comes and plays that particular claw machine, making note of how many people it takes until someone wins a prize.
Determine when the claw machine is going to pay out next. Each machine is calibrated to pay out after a certain amount of times used, so count the number of plays it takes between each win and you will have determined the machine's pay-out cycle.
Play the claw machine the next time it's supposed to allow someone to win. You should have a significantly easier time winning a prize this time around.
