I'm new to pygame and currently I'm working on creating a memory game where the computer displays boxes at random positions for like a second and then the user has to click on where he/she thinks those boxes are. It's kind of like this: Click Here
However right now I'm having a few problems. I'm not really sure how to make the computer display the boxes with like a letter or symbol e.g. 'T' or '%'. (I've already made the grid). Also does anyone know how to add increase the players score when they get the right box?
