A game that lets players to experience software development is an excellent way to introduce coding and programming concepts like loops and conditional statements. Zachtronics Shenzhen I/O is one game that accomplishes this. It puts players in the shoes disgruntled engineers who work for a dull firm and have to create computer chips by hand. They are given increasingly challenging circuits to create, starting with making lights blink in a specific pattern.
The interface of the game is very similar to web browser’s developer tools and teaches scripting. Screeps is a great example that incorporates JavaScript code with massively multi-player online gameplay in order to create self sustaining colonies. Both games are excellent at teaching the basics of concepts and slowly introducing other players.
