Logic Foundry
Logic Foundry is a circuit-building puzzle game where every solved design becomes a reusable chip.
If Chip Builder left you wanting something story-driven and relaxing, you have options. These games could fill that gap nicely.
Hard Chip is a 3D simulation/puzzle game about building processors focusing on realism. Explore the world of semiconductor chip design and delve into the intricacies of CPU logic, floor planning, and propagation delay.
Relaxing, Minimalist
Start with a single logic gate and puzzle your way up to a working CPU. Turing Complete walks you from NAND gates through arithmetic, memory and assembly until a computer you built from scratch runs code you wrote for it. Then the sandbox opens and you can build whatever you like, screens, sound and all.
