A game that allows players to play with software development is a great method to teach programming and coding concepts such as 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 boring company and have to build computer chips manually. They are presented with increasingly difficult circuits to design, starting with making lights blink in a certain pattern.
The interface in the game looks very similar to developer tools found in browsers and also teaches scripting. Another great example is Screeps which blends JavaScript programming and massively multiplayer online gameplay to build self-sustaining colonies. Both games do an excellent job of teaching fundamental concepts while also slowly introduce new ones.
