Circuit Crafter Lab

Connect the pieces. Power your inventions.

An electronics puzzle adventure: place wires, switches and components to light a lamp, spin a motor or sound a buzzer, guided by Sparky the robot.

Circuit Crafter Lab is an electronics-building puzzle game. Across five worlds and 20 hand-built challenges you place batteries, wires, junctions, switches, buttons, resistors and polarity-sensitive LEDs on a grid, and a genuine graph-based simulation (BFS reachability over the placed network, not a scripted check) decides whether power actually reaches a lamp, motor, buzzer or LED -- including correctly handling short circuits, reversed LEDs and multi-branch parallel power. Sparky, a floating robot mascot, gives contextual hints drawn from the live simulation state.

How to play

Tap or Click: Tap a part in the palette, then tap a grid square to place it. Tap a placed part to turn or remove it.
