Scientists at Zhejiang University in China have figured out a pattern to rock paper scissors that may give you the upper "hand" next time you play.  The experiment called for 360 students ro play 300 rounds of rock paper scissors. What they observed was a common strategy that all players seem to universally use.

Basically, if someone wins a round they tend to stay with the same move.  For example, if your opponent throws "rock" and wins, they're more likely to throw "rock" again.  If they lose, however, they generally rotate their hand clockwise.  So if in the same example they throw "rock" and lose they will most likely go to "paper" and then on to "scissors" if they lose once again.

We decided to let Meat Sandwich test out the method.  How did it work?  See for yourself:
