About this gameFull description from Steam
-= LEARN =- Everything in a computer can be constructed from a basic component called a NAND gate. You will be challenged through a series of puzzles, to discover the path from NAND gates to arithmetic, memory and all the way to full CPU architectures. If you complete this game, you will have a deep understanding of how assembly, CPU instruction sets and basic components are related. And you will understand how programming concepts like if statements, loops and functions actually work in assembly and hardware. -= BUILD =- The game is built on a powerful simulator, that gives you total freedom in how you solve levels or create your own computers. Wire up screens, timers, sound, keyboard input and network components to create whatever you want. You can even design a unique assembly language for your computer.

  1. The story is back, the alien is out

    The alien has been replaced with a new character. I think this change may upset some players, but it is something I have wanted to do for a while. The TLDR reason is that he is too silly in a way that I don't feel represents the game. The…

  1. Turing Complete 2.0 status update

    I have been holding out on writing a new post until the 2.0 patch was finished, but it has been too long, so here is a status update. The good news is that you can play the 2.0 alpha already. Right click on the game in your steam library…

  1. Where is the patch?

    A lot of really hard work has gone into the next upcoming patch. It has taken a long time to get this one ready though (and it still isn't done yet), so some new players are asking if the game is abandoned. It certainly isn't! Here is a…

  1. Verilog export added

    This update brings a verilog exporter to the game. Verilog is an industry standard hardware description language. With your favorite architecture exported to verilog format, you can theoretically simulate it with other simulators, simulate…

  1. Update note

    Color blind mode was finally added. The red "OFF" color is replaced by purple, since green / purple should be differentiable for all major forms of colorblindness. Also the purple is brighter so it can be distinguished from contrast as…

  2. The schematic hub is live

    Check out the schematic hub, it is finally live and there are already a few really cool things uploaded. Players who have 10 total upvotes or more between all their uploads on the 10th of August will get a badge on their profile.

  1. Upcoming new feature - Schematics hub

    It is finally time to add the feature that I have earlier referred to as "sharing". This will be in the form of an in game interface called the Schematics Hub, where players will be able to upload architectures or custom components and…

  1. Embracing realism and short term roadmap

    For a while now I have been working on removing some of the common critiques people had regarding the realism of the game. The main changes have been adding latches and the big change you can watch explained in this video. It is in a video…

  1. Patch notes

    Components now have to be connected to an input to simulate. Watched state had a major upgrade. In the component factory, use a "Watchable state" component to decide what state should be exposed on the custom component. This also adds a…

    Patch notes
  2. Console and FileRom have been added

    This patch brings the file rom, while the console was added a few days ago. The console is the first of a couple of display components that are planned. It allows you to print colored characters to a 80x24 display. You can use this for…

December

  1. Introducing the Delay Buffer

    A new idea was suggested which was just too good not to adopt. Instead of having the 1 bit memory be the basis for all memory, it is now a new delay buffer component. All the delay buffer does is take an input and output it the next tick.…

    Patch notes
  2. Refactoring patch complete

    This patch completely reworks how simulation of schematics work. This should increase simulation speed, fix random crashes from a memory leak and a race condition and make UI components work in fast simulation mode. This might not sound too…

November

  1. A debrief and the road ahead

    Debrief The original plan to have a "soft launch" of this game and scale up the player base slowly completely failed. Believing that games don't become popular without at least a bit of marketing, I thought I was well prepared when the game…

  2. New save system and how to fix missing IO components

    The save menu has been upgraded with the following features: - Folder support - Use filenames up to 45 characters - Add descriptions to your schematics - Rename custom components without having them disappear in your architectures - Get a…

  2. Fixes performance drops in long play sessions

    Some of you have been building large circuits and have been complaining that frame rates started to drop after playing for a while. This patch should fix that.

  3. Custom component link moved

    This patch contains lots of little updates I want to get out there, but I wanted to give a heads up about the following: The link from architectures to custom components is now found in the custom component panel. So click on the custom…

  4. Moved decoder level

    In this patch the decoder level was changed and moved to an earlier more natural place. Your old decoder solution will still work but some of it might be outside the level boundaries. If this bothers you, just create a new circuit and solve…

  5. Changes to the level map

    The player base grew by 100x over night so lately there has been a lot quick hot fixes for game breaking bugs. Those were uploaded as soon as I could. In this patch though, you will likely notice that layout of the level map has changed in…
