Your objective is to do the elecric wiring in a kitchen, connecting all the different appliances. Each appliance must be 'wired up' with one connection, not more or less, and there must be no disconnected wire ends. You will have a short time to review a 'blueprint' before starting. Wiring parts (cords, junction boxes etc) are fed from the left, by touching on a tile in the kitchen, the rightmost part is placed. If a part gets misplaced, touch it again, and it will go back to the 'feed queue'. If the feed queue reaches the right edge, the level fails.
