Logic Playground is a sandbox for building living circuits on an infinite grid. Signals aren't just on or off they carry strength 0–15 and fade as they travel, so distance matters, timing matters.

A full toolbox of parts.

  • Wire that decays, instant wire that doesn't, and bridge blocks that cross two signals without touching.
  • Torches (invertors with configurable sides), repeaters with adjustable delay and a lockable latch, and comparators that compare or subtract.
  • Levers, buttons, and analogue dials (0–15) in; colour-coded lamps out join lamps into larger fixtures that light as one.
  • Wireless transmitters and receivers linked by channel name or just paint them the same colour and they find each other.
  • Multiple layers connected by "Via" blocks, for some 3d dimensionality.

Turn builds into chips. Select any working circuit and compile it into a single reusable component with named pins. Your chips live in a library, can be rotated, flipped, nested inside bigger builds, and travel with your save files.

Made for big projects.

  • Paint tool with a full HSB colour picker and eyedropper for organising sprawling builds.
  • Drive and Tape for ease of storage and programming.
  • Select, copy, move, paste add to and subtract from selections for odd-shaped grabs.
  • Text notes and Read-outs for labelling. 
  • Pause, Step and Speed Controls for debugging tick by tick.
  • A chunked simulation that keeps huge worlds fast, and a compact save format to match.
  • Share creations as files, and load them either as a whole world or as a part you paste into your own.
