Game using React JS

Hi all, I have only coded for Rock, paper scissor game with minor tweak ( a reset button ) , although the bonus round is as easy as the former, but I wanted to incorporate both the rounds in one app so that user can switch between what kind of game he/she wants to play.

Unfortunately, I wasn't able to figure out a UI layout as to how I am going to manage the switch b/w the 2 types. Let me know a layout which could allow me to place a switch to toggle b/w the games.
