UNO, America's No. 1-selling card game, has a whole new twist. You'll still encounter all the elements that make UNO so unpredictable and challenging, but add to that a motorized card launcher that shows no mercy and you've got UNO Attack. The object of the game is still to get rid of all your cards. The UNO command cards direct the game by telling players when to trade hands, discard, reverse the playing order, or skip a player. Beware the dreaded Hit command, though, as this translates into a game of Russian roulette. You never know when the card launcher is going to fire off a stream of UNO cards just for you! For 2 to 10 players. Requires three C batteries (not included). 112 cards as follows: 18 Blue cards: 2 each - 1 to 9 18 Green cards: 2 each - 1 to 9 18 Red cards: 2 each - 1 to 9 18 Yellow cards: 2 each - 1 to 9 8 Hit 2 cards: 2 each in blue, green, red and yellow 8 Reverse cards: 2 each in blue, green, red and yellow 8 Skip cards: 2 each in blue, green, red and yellow 4 Discard All cards: 1 each in blue, green, red and yellow 4 Trade Hands cards: 1 each in blue, green, red and yellow 4 Wild cards 2 Wild All-Hit cards 2 Wild Hit-Fire card 2010 Edition Changes: Trade Hand cards are replaced with another set of Discard All cards Wild All-Hit and Wild Hit-Fire cards are replaced with 4 Wild Attack-Attack cards
