I know I must be missing something there's empty plug slots. This is the first time I've ever looked at this game… I think there should be something on the right hand side underneath the stickers, but I don't know what it is and I don't know what it looks like. Also, on the left board second photo there appears to be a vacant plug that I believe should have something connected to it.
