Four games

Live Wires

Turn the wire tiles until the battery lights every bulb. A loose wire end shows where the circuit breaks.
Gear Up

Drag gears between the motor and the dial so it turns the way its arrow points. Meshing gears turn opposite ways.
Spare Parts

A memory game: turn over two cards at a time and find every pair of the Professor's parts. Some of them look alike.
Blueprint

Drag brass plates into the outline and turn them until they fill it exactly. On hard, some need turning over.
