Lunch money game: Bloody knuckles! Tarantino style!

When I moved to Croatia the kids in school explained me how to get someone else's lunch money quick and easy. No worries, violence and bully stuff are not involved. It's basically a test of how though you are and you are geting a REWARD!!! All you need is a coin and a flat surface, a table will do fine.

The Rules

The rules are very simple. First all players have to spin their coin on the table, tha last coin spinnig gate strike first. The coin which stops spinnig first is doomed. The owner of that coin has to put his fist on a table / flat surface and not to move his fist or he will be disqualified and lose his coin.

You have to catapult your coin using your thumb into hes knuckles. Be careful not to miss, because it's gonna get very painful the longer you play.
Switch place, put your fist on the table and take the pain!

Remember if you pussy out, you will lose your coin.
No coins, no lunch, I learned it on the hard way.
But keep in mind that if more players are involved it can get very bloody, like in Tarantino movies.
