In plain words

This educational puzzle game challenges players to construct increasingly complex computer components through a series of tasks, beginning with basic logical gates and progressing toward a fully programmable computer. Designed for those interested in understanding how computers work at a fundamental level, the game teaches hardware design principles through hands-on problem-solving. Players advance through graduated challenges that build upon previous lessons, making it suitable for students and hobbyists seeking practical knowledge of computer architecture.

    I built ChipBuilder to make computer architecture more approachable through interactive puzzles. You start with basic logic gates like AND, OR, and NOT, then gradually combine them into adders, multiplexers, memory, an ALU, and eventually a complete CPU. Once you've built the hardware, you can write assembly programs that run on the processor you created. The game is inspired by courses like Nand2Tetris, but everything runs directly in the browser with a visual circuit editor, simulations, and progressively harder challenges.

    Inspired by games like Turing Complete/Virtual Circuit Board/Logic World, I tried to make a mix of aseprite and wiredworld/wired-logic, the idea being the user can build a digital circuit using a "fullstack" pixelart creation workflow. The circuit is just an image. The primitives are (i) connected wires which have undefined, 0 or 1 state during simulation (displayed brighter or darker in function of the state) and (ii) NANDs, which are little pixel triangles. During simulation the user can interact with any wire by clicking on it, toggling its state, which is cool for messing…
