Hey guys, So the game im trying to create is a 2d array game that is a matching game. it is a 4x4 array and each card has a "imageNum" given to them which decides what picture each card will have. When i run the scenario the cards flip once, and if they match they do work sometimes but sometimes the cards simply dont match but it says it works and sometimes when they dont match, they flip back but they end up making it not able to click again. Could someone help please?
