Signal Sandbox

Build absolutely anything in Signal Sandbox! Create digital displays, working computers, synthesizers, and so much more. Share your creations on the Steam Workshop, and build in real time with your friends. Signal Sandbox is the ultimate analog sandbox simulation.

In Signal Sandbox, you can see and hear your analog creations. Build with modules like buttons, knobs, faders, oscillators, screens, logic gates, and more. You can plug absolutely anything into anything!

Choose from 50+ premade modules, in categories like music, logic, electronics, and more. One wire carries everything - Signal Sandbox is a pure analog simulator. Hooking (almost) anything up to a speaker can get you on the road to sweet sound synthesis. And if audio isn't your style, build out any number of other projects that use displays, boolean logic, and more. The sky is the limit (until you decide to actually build the sky).

No rules, no wrong moves. Just plug and play to see what you can create!

What's better than building a Rube Goldburg rickroll machine by yourself? That's right, building a Rube Goldburg rickroll machine with friends! Invite your friends to join your tinker session. Build together, tweak together, and play together. Don't think you are up to the challenge of real-time analog collaboration? That's okay - you can browse and play other players' creations from the Workshop with your friends too!

You share the same multiplayer sandbox with your friends in real time. Dragging and dropping byte-sized modules has never been so fun!

Made something you're proud of? Or, at least, made something you want to share? Look no further than the Steam Workshop. Boot up someone else's wonderful contraption, play with it, then edit it to make it even more wonderful!

Load up someone else's creation to play with, or just see what the community is building today. The choice is yours!

Okay, you've made it this far. You must be, like, REALLY into signals. That's cool. Here's what's actually running under the hood of our cozy little pixel art:

Full Analog Simulation Engine

192kHz Audio-Agnostic Sim

Realistically Modeled Modules (Whatever that means)

A Tiny Hamster We Call "Tim" Running In A Wheel for Power

TLDR; Signal Sandbox is a multiplayer analog simulator sandbox where you build contraptions with plug-and-play modules that have satisfying pixel graphics all with a real-deal simulation running under the hood.
