I really enjoy trying to figure out Doodle Fit. You have the option to change the background (2 choices) and have the music on or off. It also allows you to choose from 5 different languages. There are 4 different levels. To complete a level you need to fill the shape with all the blocks available. Some shapes have more than one solution to solve it. I challenged myself to find those solutions as well. It is quite the challenge. Once you pass the first level you may continue onto the second level. There were moments where I was a little confused with how to get to certain puzzles, so that is why I gave it 4 stars instead of 5. Some of the easier puzzles can be completed by younger children like my 7 year old. This game is geared for older children to adults.
