Can I use software that I purchased to create my game?
In the platform-specific categories (e.g. Gamestar, Scratch, Gamemaker and Kodu), you must use the the freely-available version of those
tools (including special versions made available specially for the Challenge as we do in Gamestar for example).
In the Open Platform category, you can use any tool you want, including paid tools. The only requirement is that the game you make
must be playable by the judges without them having to install or purchase any special hardware or software.
