So the final boss is this wizard guy and he has cards set up around a room face down in a 4x4 grid. You have to match 3 cards together to eliminate those sets of cards. There are 5 sets you need to get rid of to defeat him. However the catch is if you don't match 2 or 3 of those cards together, you're hit with a long attack animation depending on which card you last flipped over. Also the 16th space that's not a card is the boss, and if you flip him over by chance he'll chase you around the room for like 12 seconds. And where he appears is random, so he could appear over a card you need to flip over to match 3 together if you need to. It's really bad lol
