You have to get Santa to the portal in each level to help him deliver presents. In every level, Santa is swinging on a string. There are usually other presents and stockings in the way between him and the portal. You have to cut his string at the optimal time to land him in the portal. Different tools like bellows and slopes can help you deliver Santa to his destination. Each level requires more thinking and planning than the one before it! If you fail, don't worry. You can always try again—just don't let Santa miss any of his present deliveries.
