Sample Projects:

Any changes you make to a sample project will be overwritten if you open another project. If you don't want to accidentally lose your progress, then you can copy the sample code to one of the custom projects below or start an entirely new custom project.

Custom Projects:

You can create your own custom projects and save them, or any of the sample projects, to your computer at any time. In order to upload your projects to the Playground, you must first select one of the projects below to assign your project to.
