The cool thing is, while they’re much faster now denser now, and faster, and we have much simpler ways of interacting with them, and storage, both chip and magnetic, hold much more data, and each of these things has improved by a factor of billions or even trillions, computers still basically operate on these same principles.

This video mostly concerns itself with explaining how basic computer circuts are made. It makes for fairly dry viewing if you don’t know anything about electronics or circuit diagrams, but maybe it’ll be interesting anyway, from a historical perspective.

We love it when we find weird and unique indie games to tell you all about! Our alien friends to the left herald these occasions.

NANDgame is one of those puzzle games that’s really an educational game in disguise. By hooking up wires and relays, then logic gates, then larger pieces of basic computing hardware, you construct a basic processor from first principles, step by excruciating step.

Of course, the difference between a puzzle game and an educational game is only if the skill the puzzle requests you to learn has some objective use in our physical world. Tetris masters are robbed by the rest of the human race that their unique skill can’t be used to write software or design cars or something, for the kind of effort involved in getting good at all these things is exactly the same. This puzzle, at least, can get you on the road to designing low-level computing hardware, or at least started on that road.

Now that’s out of the way, I’m not completely happy with this introduction to computing architecture. It is true that you can start with NAND gates and, from them, derive all the other logic gates, and from there the rest of computing in its entirety, and this game has you do essentially that.

But NANDs are not the simplest gate to understand. Even their name comes from combining two other gates that you’re not introduced to first. And forcing the player to invent one out of relays, which you are actually required to do here, is a difficult first step. If you aren’t already well-versed in the kind of thinking this involves I’d suggest making use of the hints for each level, because the game gives you no other aid. It is a real trial by fire, and without prior exposure you’ll be staring at the relays for a while wondering not just what you’re supposed to do with them, but why.

But if you can power through them all, again using hints, it is really rewarding to know that, if you had the parts, you could construct a simple processor from first principles. It is difficult, but this is a good introduction. I’d treat it as kind of a test, and that the actual game is learning what you’re supposed to do to win by looking it up from other sources, including the help system. That’s to say, it’s all bosses, with the skills learned to defeat them coming from what amounts to GameFAQs.
