NOT A GAME, more of a gadget. Enter two options (i.e. McDonalds and Wendy's). Enter the number of matches you want to be played. Put in a big number if you want. Don't worry, it's lightning fast and automatic, and just like real Paper Rock Scissors, any option will only win 1/3 of the time!!! It's amazing!!!
By the way, if you wonder why the total scores don't add up, it's because roughly 1/3 of the matches end in a tie, and they are thrown out.
