Chip Builder

Build a working computer, one gate at a time

ChipBuilder is a story-driven puzzle game about digital logic. You are a junior engineer at ChipCorp, and your mentor, Dr. Ada Chen, has one goal for you: build a working CPU with your own hands, starting from a single switch.

Key features

• 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 exact behavior it has to produce. No shortcuts, no guessing.
• Lessons that tell a story. Each chapter opens with a briefing from the lab, with hints and a step-by-step mode whenever you get stuck.
• From sand to silicon. In the final chapter you take your design to the fab: grow the crystal, lay out the transistors and package a modern 3D chip.
• Play your way. Choose Guided, Normal or Hard, earn XP, and climb the ranks from Intern to Chip Architect.

Your journey

• Chapter 0, Silicon & Switches: build logic out of the only thing a chip really has, transistors.
• Chapter 1, The Spark of Logic: the gates that process 0s and 1s.
• Chapter 2, The Art of Combination: adders, multiplexers and decoders.
• Chapter 3, Memory Takes Hold: latches, flip-flops and registers.
• Chapter 4, The Storage Vault: RAM, ROM and address decoding.
• Chapter 5, The Brain's Calculator: the ALU, the arithmetic and logic powerhouse of the CPU.
• Chapter 6, Building the Brain: program counter, control unit and datapath.
• Chapter 7, The Language of Machines: machine code, assembly and algorithms.
• Chapter 8, The Chip Architect: pipelining, caching and ISA design.
• Chapter 9, From Sand to Silicon: manufacture the chip you designed.

10 chapters. 43 levels. One working CPU, built by you, one gate at a time.
