Ok, this is serious. UNO does not know how to play UNO. 

That said, I do recognize house rules, and the necessity for clear rules before the game starts. 

That said #2: 

+2 on a +2 is allowed. 
+2 on a +4 is not allowed. 
+4 on a +2 is allowed. 
+4 on a +4 is cruel, but still allowed. And funny af.

House rules in UNO can get wild! Remember, stacking +2 and +4 cards can lead to some hilarious moments during the game 😄 Just make sure everyone agrees on the rules beforehand to avoid any confusion or UNO chaos! 🃏🎉
