From the Manufacturer:
The UNO classic card game goes revolutionary! When a spin card is played, someone must spin the wheel. Will luck be on your side? Will players get to discard cards, be forced to pick up more cards, or even exchange hands? In a single turn, everything can change! Players can come from behind and suddenly take the lead. It's fast-paced fun that'll make your head spin! Includes one UNO Spin? wheel and 112 UNO Spin cards and instructions.
