About Spark Lab
Spark Lab is a puzzle game about electricity. Electricity needs a complete loop, called a circuit, from one end of the battery all the way round to the other. Tap the wires to turn them until the loop is complete, and watch the electricity flow and the bulbs light up.
Later circuits have two or three bulbs, motors that spin and buzzers that buzz, extra wires that lead nowhere, and switches you must close. In the Conductor Test you fill a gap with a coin, a key, a pencil or a teddy, and find out which materials are conductors (metal) and which are insulators.
Every circuit is made fresh each time, and every one can be solved. Each circuit you finish lights up a house in the town. Your progress is saved on this device.
