At a glance

Shenzhen I/O is a Zachtronics puzzle and programming game about designing electronic devices. You build circuits from components such as microcontrollers, memory, logic gates and LCD screens, then write programs in a compact assembly language whose instructions can run conditionally. An included manual offers more than 30 pages of datasheets, reference material and technical diagrams, making the game’s electronics and coding central to play. The setting places you at Shenzhen Longteng Electronics, where you meet a cast of coworkers. Outside the main circuit-building challenges, a sandbox lets you create and test your own games and devices, and a solitaire variant offers a change of pace. It is a single-player game for Windows, macOS and Linux, with Steam achievements, Workshop, Cloud and Leaderboards, plus a level editor and Family Sharing.
