I'm trying to make a game for my nephew. He is really into basketball and he is only 7. As a 7 year old, he needs to practice with his memorization. I am trying to design this game where you match cards with each other. I am making the cards not visible when they are both clicked, but I can not seem to make them go back when you click one and then click another (being the wrong one). I was wondering If I should use functions as there are many cards that have to do the same thing.
