Puzzle Elements

• Blue door
• Emitter
• Inverter
• Pressure plate
• Receiver

Overview

The puzzle is composed of three rooms. The first one holds an Inverter and a red Emitter. A Blue door controlled by a Pressure plate leads to the second room, which holds a second Inverter. On one side, a small cell contains a blue Emitter. On the other side, a Blue door controlled by a blue Receiver leads to the third room, which contains a third Inverter and a last Blue door to the Progress Wheel.
