There was a similar post regarding EMO and playing Rock, Paper, Scissors discussed not to long ago. I’ll share this here as well to help.
I’ve also created a video on how to play the game. (see below video)
It is best to have good lighting and also keep a fair distance when playing with EMO so he can clearly see and distinguish your hand gestures.
Ohhh as mentioned in my other post, beware that EMO does cheat as well
