There are 10 chapters, and each one has 3 levels. The first ones are usually easier and then it gets a little bit harder. As you progress you get all the achievements, so you can't even miss any of them.

If you're too lazy to complete a level, there's a "bot" who will complete the levels for you. Just click on the little "play button" on the top right of your screen.
