Still thinking about Virtual Circuit Board and its retro and minimalist tone? These games line up well for what comes next.
Invent a new computer! Logic World is a first-person sandbox simulation game that's all about digital logic. Play alone or with friends, design unique machines, build up layers of complexity, and experience the joy of circuits!
Minimalist, Relaxing, Replayable
CRUMB is a 3D circuit sandbox where you build electronics on a virtual breadboard without burning a single component. Wire up LEDs, transistors, logic chips and a programmable microcontroller, then watch your circuit run in real time. A calm, low-pressure workbench for learning how electronics actually work.
Relaxing, Replayable
Build circuits from microcontrollers, memory and logic gates, then program them in a tiny assembly language to meet real spec sheets. A demanding puzzle game about doing more with less, set at an electronics company in Shenzhen. When the code fights back, there is always solitaire.
Retro, Minimalist, Relaxing
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.
Minimalist, Relaxing, Replayable
Lay out real chips pixel by pixel. Wire length is delay, layers are speed.
