IT THINKS! - Build Your Own GPU

From one logic gate to a computer.

IT THINKS! is a hands-on hardware puzzle game about discovering how computers grow. Place parts, draw wires, watch signals move, and prove each design on a live test bench. Your first component is NAND: a tiny logic gate with two inputs and one decision. From there, your designs grow into arithmetic, memory, a programmable processor, parallel cores, matrix multiplication, and finally a chip that recognizes your handwritten digits.

Build it. Test it. Ship it.

Complete 36 handcrafted contracts across six eras, from a small workshop to an AI lab.

Turn working circuits into reusable chips and build a catalogue of components you designed yourself.

Program the hardware you built with a compact assembly language and run the same kernel across many cores.

Balance real architectural trade-offs such as area, ticks, memory bandwidth, power, and parallel efficiency.

Learn at your own pace with optional hints, the Master's Notebook, and skip tests for concepts you already know.

Make every solution yours with exportable die views and looping GIF captures.

No electrical-engineering background is required. Build by doing, inspect what happened, and improve the machine one clear step at a time.

Language support at launch: The interface, tutorials, and all in-game text will be available in all 15 languages listed on the store page.
