LECTRIC
The circuit-building puzzle game that teaches you real electrical engineering.
Build circuits on a live simulation. Light lamps, tame LEDs, blow fuses on purpose, hunt down hidden faults with a multimeter — and learn how electricity actually works while you play.
Learn real electronics, one puzzle at a time
Real physics, not flashcards
Every wire carries genuinely simulated current — the same nodal analysis used in professional circuit simulators, running live at 30 frames a second. If your circuit works here, the math works in real life.
From first lamp to transistors
A 114-level campaign that starts with lighting a single lamp and climbs through Ohm’s law, series and parallel circuits, capacitors, relays, diodes, and transistor logic — one small "aha" at a time.
Think like a technician
Troubleshooting levels hide a faulty component in a working design. Grab the virtual multimeter, probe voltages and currents, find the culprit, and fix it — the exact skill real engineers use daily.
A community of puzzle builders
Players design and publish their own challenges with the built-in editor. Every published puzzle is machine-verified to be solvable, and the best ones rise by community vote.
