Best Easy: —. Tap a tile to rotate; power flows from the glowing Core.

Zerdly Circuit is a free, no-download logic puzzle. Rotate the wires so power flows out from the Zerdly Core to every tile on the board. Every puzzle is generated fresh in your browser, so there is an effectively unlimited supply — and nothing is uploaded or stored.

How to play

  1. Tap any tile to rotate it a quarter-turn.
  2. Power spreads from the glowing Core through connected wires — lit tiles turn teal.
  3. Connect every tile so the board reads 100% powered to complete the circuit.
