A deeply methodical and satisfying puzzle game where you assemble circuits and write assembly code, feeling like a true engineer at a busy electronics company.

What players say

Players say it captures the real feel of hardware engineering work, with a custom assembly language and datasheets to print. The included solitaire game is a fan favorite. Some find the lack of debugging tools frustrating, and beginners may need a video tutorial to start.
