Can RPS be played when there is nothing to be decided?
Never. According to English laws dating back as far as 1842, RPS matches may only be played to make a decision on something. However, often frivolous excuses are made up in order to play. Due to the ensuing public outrage, the law was later amended to include RPS games for “honour”. Since the inception of the World RPS Society the vast majority of games have indeed been for honour.
