Angry Birds On Thin Ice is the second instalment of the exciting skill and action game based on the best-selling phone app, Angry Birds. It lets players build, launch and destroy with fun new features, including pigs with helmets, breakable ice block building pieces, an "exploding" TNT box and a new large red bird character. Players draw a card and build the structure shown before their opponents launch Angry Birds in an attempt to knock down the structure-and the pigs-to win points. Angry Birds On Thin Ice includes 2 Angry Birds, 3 green pigs, 1 slingshot-style catapult launcher, structure pieces and mission cards.
