I do not know the origins of the game but it has been around for a long time.
The point is to arrive at a decision about something (eg, who is to do something or not as the case may be) by eliminating possible candidates. The beauty of Rock (or Stone as we used to say), Paper and Scissors is that the hierarchy of 'superior' hands is an eternal loop, viz, Scissors cut Paper, Paper wraps Stone, Stone blunts Scissors and so on 'ad infinitum'. Thus, unless both players show the same hand (in which case they play again), whichever 2 different hands are shown, one of them MUST beat the other.
Unlike tossing a coin, this has the advantage of allowing both participants a choice in the 'hand' they declare.
Hope that makes sense.
