If you play UNO... you probably like something like this:
You match a card in your hand to one that’s been discarded, based on the number or color, then follow what the card says. for example if you get a 'Draw Two' card. Whomever gets rid of all their cards first, wins the game!
However, if you play UNO like this... then you’re playing wrong! That's according to the official UNO instructions on Mattel’s website!
Apparently, you’re supposed to get points for all the cards your opponents are still holding, as follows in the “Scoring” section!?!
