Build-a-Circuit Puzzle

How to Play

In order for a lightbulb to turn on, electricity needs a continuous, unbroken path to flow from the power source to the load.

• Select a Wire: Choose a straight or corner wire from your inventory.
• Place & Rotate: Click on an empty square in the grid to place the wire. Click it again to rotate it 90 degrees.
• Eraser: Select the Eraser tool and click a wire to remove it. You can also use the "Reset Board" button to wipe everything and start over.
• Complete the Path: Make sure the ports of adjacent wires align perfectly to create an unbroken path from the Battery to the Lightbulb.
• Test: Click "Test Circuit" to run power through your grid. If the path is continuous, the bulb will light up!
