I've tried all kinds of tutorials and none of them apply to what I need. I'm making a small card game and I've been having difficulty trying to understand all the functions. I need help on creating a script for my card game. I was wondering how to make the cards know it's been matched up with it's pair without using randoms or anything. I don't want to move the positions of the cards, just simply, if they're matched they light up, if not they go back. I'm really not computer literate or have much experience with programs like these.

Here's my project:
