There are 3 levels with stars to show difficulty. The hardest level is quite challenging while the easiest level quite is easy although it can be diffictult for children under the age of 6 or so. There are about 9 different songs and each level plays the same songs but at different difficulties. This is not a professional DDR game, but it's great for kids and great if you don't have or don't want to buy a playstation. Overall, this is a fun kids dance game and I would recommend it to everyone!
