A game that lets players play with software development is an excellent method of teaching programming concepts and coding concepts techniques, including loops and conditional statement. Zachtronics Shenzhen I/O is one game that accomplishes this. It puts players in the shoes angry engineers who work for a non-existent company and are required to design computer chips manually. The circuits they’re required to design become more difficult beginning with making the lights flash in a specific pattern.
The interface of the game looks very similar to tools used by developers in browsers and teaches scripting. Screeps is a great example, which incorporates JavaScript code with massively multi-player online gameplay to build self-sustaining colonies. Both games do an excellent job of teaching the basics as well as slowly introducing new ones.
