About This Game

Build Computers From Pixels

In Circuit Artist, every circuit is an image.

Draw pixels like MS Paint — but each pixel is a wire or gate. From simple NAND gates you can build:

• adders
• memory
• ALUs
• entire CPUs

Then run the simulation and watch signals propagate through your design.

Real Signal Propagation

Wires are not instant.

Long wires and heavy fan-out introduce delay, meaning layout matters.

Watch signals travel through your circuit in real time and optimize your design like a real chip engineer.

Debug With Time Rewind

Circuits can fail in subtle ways.

Pause the simulation and scrub time backward and forward to see exactly what happened.

Perfect for debugging complex logic.

From NAND to CPU

Everything is built from one primitive: NAND.

Start with logic gates and scale up to:

• multiplexers
• registers
• memory
• full processors

The only limit is the size of your canvas.

Sandbox and Challenges

Two ways to play:

Sandbox

• Build anything you want

• Experiment with complex architectures

Challenge Mode

• Solve increasingly complex circuit problems

• Learn digital logic step-by-step

Circuits Are Just Images

Your circuits are saved as PNG files.

That means you can:

• share circuits easily
• remix designs
• inspect how others built their computers

Fully Open Source

The simulation engine is open source.

Explore the code, modify the game, or build your own tools.

Written in C using Raylib with Lua scripting.
