The usual Uno (including themed editions without new cards) rules - Players race to empty their hands and catch opposing players with cards left in theirs, which score points. In turns, players attempt to play a card by matching its color or number to the topmost card on the discard pile. If unable to play, players draw cards from the draw pile until they are able to place a card. Wild and special cards spice things up a bit. Additionally, when playing their penultimate card from their hand, players must shout 'UNO' or face a forfeit of drawing two further cards. Based on the Disney Channel Movie High School Musical. WHAT MAKES IT DIFFERENT FROM TRADITIONAL UNO: 'Duet Card' There are 4 pairs of characters in th "High School Musical." When you play the Duet card, all other players must discard one of the pairs from their hand (2 cards). If a player cannot discard a pair, they must draw 2 cards from the DRAW pile and add those cards to their hand.
