Random _x

i’m wanting to create a guessing game…like “follow the queen” or better yet, you know the game where you have 3 cups and you put something under one of em then you mix em up and have the player guess the right one?
That’s what im trying to do, but do this using as.
So I’m already picking apart the random movement tutorial but that’s a tad too much of what i need done. Anyone have any rough ideas on the best way to accomplish this. Not really asking for someone to do it for me (i like to learn by the trial and error process) but more so how it should work?
