Another older but really good Zachtronics game that I like to recommend is KOHCTPYKTOP, which simulates something similar to MOS semiconductor logic. Your job is to build ICs which conform to predefined stimulus/response patterns.
Unfortunately, it requires Flash, so it may be difficult to get to run in a browser nowadays. Totally worth it, though!
