Redstone Logic

Design redstone circuits block by block, watch them run tick by tick, then build them in your world. A pocket workbench for redstone engineers.

Every redstone part

Dust, torches, repeaters, comparators, pistons and sticky pistons, observers, slime and honey, lamps, doors, note blocks and more, on a grid you can stack layer by layer.

Test it live

A tick-accurate Java Edition simulator: flip a lever and watch the signal travel. Pause, step one tick at a time, and hear note blocks and bells play.

Then build it for real

Follow the layer-by-layer build guide, look at it in 3D, or export a structure file or schematic to load straight into your world.

No ads, no account

Your circuits stay on your phone. Start from ready-made logic gates and example machines, or from a blank grid.
