Build it
Complete 36 handcrafted contracts across six eras, from a small workshop to an AI lab.
A hardware puzzle game
IT THINKS!Build Your Own GPU
Hardware puzzleDemo available
Design the chip that powers AI. Start with a single logic gate and build a computer: wire circuits, cast designs into reusable chips, program tiny kernels, and scale your architecture into a working 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.
Test it
Turn working circuits into reusable chips and prove every design on a live test bench.
Ship it
Program your hardware and balance area, ticks, memory bandwidth, power, and parallel efficiency.
The demo includes 10 logic steps and 2 guided parallel previews. Play instantly in your browser; progress is saved in this browser.
