Why does "Browse" at the top take me to what looks like a scam shopping site? The "Pipelining" level is completely broken - big completely empty grid, no components to place, and you actually think you're going to learn _pipelining_ in a _schematic editor_? This is a vibe-coded slop project. Not interested.

Oh lord, I went to the "ALU" example, did absolutely nothing, clicked "Run Tests" - YOU WIN

You didn't test this thing at all, did you?

I have no comment about this particular product, its features or its author, you can read other comments if you want.

I advise the readers to check out not only Nand2Tetris but also Turing Complete game on Steam (and hopefully back on GOG at some point). The author came back to it and started posting updates a few months ago after almost 2 year silence. He rebuilt the engine with a huge performance boost and is now adding more and more features.

Not affiliated with him in any way, just think the game is great and his dedication to it deserves respect.

I went through Turing Complete up to a working CPU and found it incredibly fun. I then went on to build my own RV32I (simplest RISC-V instruction set) core in Verilog - if you keep a simple single-cycle design, it doesn’t end up being super complicated and not a ton of code. I’d recommend the exercise for anyone wanting to learn about how CPUs work. Also, for people interested in this type of thing, look up Ben Eater…

My 14 year old son went further in the Turing Complete, where the game shows you how to "invent" Assembly language, and he completed couple challenges after that (like writing Assembly program to make a robot controlled by the computer you built in the game solve a randomly generated maze).

FYI the author started publishing updates again; looks like he took 2 years to rebuild the game from the ground up and instead of launching it as "Turing Complete 2" he chose to simply publish it as breaking update, and is now continuing with updates to add features.

I really don't appreciate this Reddit-like snarky attitude and I usually do not respond to people like you and to ill-intentioned messages like this one, but this time I will, since you accuse me of scamming people, which is a big deal.

The post is about the game. When clicking on the Browse button and assuming you can read, you will see a collection of well-crafted products. I am not selling those myself. The website does not process payments, does not ask for donations, nothing like that.

Saying that the ALU example does not have tests is just a lie. I am not sure if you are a liar, or just frustrated about something, or maybe you're having a bad day, but for a person bragging about being an ex-employeeID at a big-tech firm and a GH-contribution-green-dots chaser, you should be more humble and think twice before accusing someone of doing illegal stuff.

Last year I remember playing a similar game where you design a CPU beginning with SSI gates, building flip flops, registers, adders, multiplexers, etc. It was fun doing this because I hadn't done any digital design for a few decades, but near the end it became frustrating because it forced you to use only certain variants of modules, which you had to adapt for the final integration. It would have been more fun if it was flexible enough to let you create your own variants and use those.

This game seems to have a similar limitation.

I wonder how people go through building such a project without ever hearing about NANDGame or Turing Complete.

For the lazy, here's a link https://www.nandgame.com/ When I played through this last year it was surprising how much came back to me from the courses I took in college, and haven't touched at all in 20 years.

i havent been able to clear level 1 of nandgame , i dont know how to make that switch work on all 4 truth tables
