Apple slipped while he was making a batch of Fizzy Fruit and dropped it all over the floor. (Don't worry, he didn't hurt himself. Apples are used to falling: off trees, on people's heads, wherever...)
Anyway, he and Orange decided to make a game of it by picking up only the pieces that were just alike and touching sides. They liked their game so much, they made a cleaner version for you to play here. So see if YOU can get all the pieces off the floor by getting rid of only the squares that are touching sides. Good Luck! (you're gonna need it!)
