Rock Scissors Paper:
It’s quite a phenomena in Korea this game. You can throw it into so many situations. You can imagine you’re playing baseball and maybe you ask quiz questions, and maybe a “rock scissors paper” determines whether the student advances to another base. Perhaps the “pitch” is a study question. The “hit” is the right answer and rock scissors paper to see how far they go (at each base an opposing team-mate can “rock scissors paper” to see if they made it past that base or not).
