You guys do know how claw machines work right?
The machine operates on a ratio of wins to losses.
So it would be every 10 losses 1 win. It depends on the machine. 1 out of the 10 times the machine will exert its full force in its grab. Its so it garuntees making a profit.
The way to win these are to watch people play it and determine how many losses it takes to equal one win. Then you just wait for X amount of people and you go when you know its a win.
