This is a multiplayer E Card game from Kaiji built with JavaScript.
It is like rock, paper, scissors. Emperor beats civilians. Slave
beats emperor. Civilians beat slave.
There are four rounds, with each round lasting three turns. The
slave and the emperor will swap after each round. Winning as the
emperor grants you one point, and winning as the slave grants you
three points. Whoever has the highest score after the last round
wins.
