The memory game section of the Monsters Band app for the iPhone/iPad is FREE today. Kids can choose their level of difficulty – 12, 20, or 30 cards to match. Points are awarded based on what level is being played. There are also time bonuses. Kids may register to build points and earn stickers but it is not necessary to do so in order to play. Very cute card memory game – love the silly monsters! Also available as in-app purchases are 3 levels of jigsaw puzzles and 3 levels of quizzes.
