What are some fun games or apps for learning programming languages?

Check out "The Farmer Was Replaced!" It's a great game for learning Python and just launched on Steam. Definitely worth it if he's into coding. There are more games like it that would be good once he’s a bit more skilled, such as Screeps.

If your son is open to it, I’d highly recommend Shenzhen I/O and Exapunks. They play like games but teach programming at a deeper level, particularly hardware and assembly language. I learned a lot about coding just by playing them!

You might want to check out Turing Tumble. It's a mechanical toy that introduces logic concepts with ball bearings and gravity. It’s not strictly programming but is a brilliant educational tool that really makes you think! If he’s looking for something more language-specific though, I'd suggest games that match what he's currently learning.

Factorio is awesome! It's a fun game that encourages logical thinking and problem-solving. Plus, it’s quite addictive, so be ready for that!

For a more hands-on approach, getting him a Raspberry Pi could be great! It’s a mini-computer that allows for all sorts of programming projects. Pair that with a cool book like "Automate the Boring Stuff with Python" and you've got a solid gift!
