Slide your finger along the case to aim, then let go to drop the treat. When two matching treats touch, they bake into the next one up: sprinkles become blueberries, then cherries, cookies, macarons, donuts, cupcakes, pies, cakes, rainbow cakes and finally the wedding cake. If the treats stack above the dotted line, the shop closes. Each game comes with three hints that show the best spot to drop your next treat.
