I've played this game before and there is a trick to it. Play the game for a while and I'll let you know. (It's quite easy) Oh and my screeny Click Click P.S. I did not cheat.
Alright, this is a bit tricky Drag your mouse (with the hand) towards the right of your screen and then right click. This should hang the hand there. Now without clicking go towards the extreme left of the screen, and then left-click. Try it a couple of times, it's hard, but an effective way to get a high score. Keep trying
