UNO(TM) Flex Card Game is based on the UNO(R) Card Game players know and love, but with a flexible attitude. Special cards let players change a card color to make a match -- a Red 4 can become a Green 4 in one flex. Power Cards and Flex Action Cards add even more bends to the game! Perfect for families, parties and game nights, it makes a great gift for UNO(R) fans and card game lovers ages 7 years and up.
