Chip Builder

Chip Builder is a story-driven puzzle game about digital logic. You play a junior engineer at ChipCorp, learning to build a working computer from the ground up, one gate at a time. You drag components from a palette onto an interactive circuit canvas, wire outputs to inputs and watch signals propagate as you build. Each circuit is checked against the truth table it should satisfy.

Lessons at ChipCorp

The narrative-driven lessons cover 12 chapters:

• Chapter 0, Silicon & Switches: Start with single transistors and build your first logic from them.
• Chapter 1, The Spark of Logic: Learn how logic gates process 0s and 1s.
• Chapter 2, The Art of Combination: Combine gates into adders, multiplexers and decoders.
• Chapter 3, Memory Takes Hold: Explore circuits that remember, including latches, flip-flops and registers.
• Chapter 4, The Storage Vault: Build memory systems with RAM, ROM and address decoding.
• Chapter 5, The Brain's Calculator: Build the ALU, the CPU's arithmetic and logic unit.
• Chapter 6, Building the Brain: Assemble a complete CPU with a program counter, control unit and datapath.
• Chapter 7, The Language of Machines: Explore the boundary between hardware and software through machine code, assembly and algorithms.
• Chapter 8, The Chip Architect: Study pipelining, caching and ISA design, then build freely.
• Chapter 9, From Sand to Silicon: Learn how chips are built and assembled in the fab.
• Chapter 10, The AI Accelerator: Discover how dedicated chips for running and training artificial intelligence are developed.
• Chapter 11, FAB CEO: Lead ChipCorp as its CEO for 35 years in a turn-based grand strategy game.

Build a computer

In a second mode, you start with one NAND gate and build a computer across 14 scored milestones. You design its instruction set, write and debug assembly programs, and connect peripherals: a keyboard, console, pixel screen, timer, sound and a network port. In the final milestone, Snake runs on the computer you built. The mode has 49 levels, and you build one working CPU, one gate at a time.
