The UNO game players love features graphics inspired by characters from the series The Simpsons.
Game play mirrors the classic card game where players match colors and numbers to get rid of all their cards.
Unique patterns on each card help identify the color(s) on that card, allowing players with any form of color blindness to play.
The special “Woo-hoo D’OH” rule adds a fun twist, where a player may be safe (Woo-hoo) or may have to add cards (D’OH):

With the special “Woo-hoo! D’OH!” card, you may be safe (Woo-hoo!) or may have to add cards (D’OH!). And when you’re down to one card, don’t yell “Ay Caramba!”, yell “UNO!”
