Turing Complete
Build a working CPU from a single NAND gate, then program it
You start with only a NAND gate and build the rest of a computer yourself. First you make other logic gates, then arithmetic and memory parts, and finally a full CPU architecture. Later levels have you write assembly to solve programming puzzles on the hardware you built. A sandbox lets you design your own computers.

About Turing Complete
It trains how computers work, from logic gates up to instruction sets. You do not need a hardware background, but the later levels get hard. It suits programmers who are curious about what happens below their code.
It is a paid Early Access game by LevelHead on Steam, for Windows, macOS and Linux. It has more than 70 levels. The developer says it will leave Early Access in 2026.
