Rock, Paper, Scissors - Linear, Non-Linear, or Sandbox? (Minor Project 3 Option 2)

After reading the "Game Structure Types" section of our course textbook, I came to the conclusion that Rock, Paper, Scissors is a non-linear game. The reason for this is because of the multiple outcomes that can result, without complete freedom. In linear games, there is one path you can follow with one outcome. Since there are three hand symbols you can throw in Rock, Paper, Scissors, it creates multiple outcomes. However, this does not make it a sandbox game, because players are restricted to throwing one of three symbols each turn. Therefore, Rock, Paper, Scissors can be classified as a non-linear game.
