Build a CPU.
One Gate at a Time.

ChipBuilder is a story-driven puzzle game about digital logic. Wire your first AND gate, then climb from transistors to registers, memory, and a full ALU — until you're writing assembly for a CPU you built with your own hands.

The Story

Day One at ChipCorp

You've just badged into the Logic Design Lab as a junior engineer at ChipCorp. Your mentor, Dr. Ada Chen, is waiting at a workbench lined with digital circuit simulators.

"Every computer ever built started right here," she says, "with gates — simple rules that turn electrical signals into computation. Ready to learn the language of machines?"

Over the following months you'll move through ChipCorp's labs — Arithmetic, Sequential Logic, Memory Engineering, the ALU Testing Chamber — each one adding a new layer to the machine you're building, until the diagrams on Dr. Chen's whiteboard finally become a working CPU under your own hands.

"A gate alone is like a single word. But combine them, and you get sentences. Paragraphs. Books."

— Dr. Ada Chen, ChipCorp Logic Design Lab

The Journey

8 Chapters, From Transistor to CPU

Each chapter is a lab at ChipCorp. Each level teaches exactly one new concept — and it stays with you, because you built it with your own two hands.

How You'll Learn

Learn by Wiring It Yourself

No lectures, no slides — just a canvas, a component palette, and a truth table that tells you the truth.

Interactive Circuit Canvas

Drag components from the palette, wire outputs to inputs, and watch signals propagate live as you build.

Real Truth-Table Verification

Every circuit is graded against the actual truth table it should satisfy. No partial credit — it either works, or it doesn't.

Narrative-Driven Lessons

Dr. Ada Chen and the ChipCorp story frame every concept, so the "why" always comes before the "how."

A CPU You Actually Assembled

Program counter, control unit, ALU, memory — every block in the final CPU is one you built and tested yourself, level by level.

From Hardware to Assembly

Cross the hardware/software boundary: design an instruction set, then write the machine code and assembly that runs on it.

XP, Mastery, and a Free-Build Sandbox

Earn XP as you clear levels, then graduate to the Chip Architect chapter and design freely with everything you've learned.
