Try to solve all the levels in this stage. If you get stuck at any level, you can see the solution on this page.
Below are the images of each level along with the code needed to complete that level. There are 11 levels in this stage. The last one is for designing the game anyway you like.
This blog post is created to support the students taking up the Code Studio courses on Code.org. I have tried to create an answer sheet for each stage which you can easily access whenever needed. If you want anything else here, please let me know.
