[DB078] A Maze of Doors

078 - A Maze of Doors

A Maze of Doors is a puzzle in Professor Layton and the Diabolical Box.

Puzzle

US Version

All the doors in the maze below only open in one direction. Each door can be opened by pushing from the direction shown below, but when approached, no amount of pulling or pushing will open it.

If you tried to go through the whole maze from the start and passed through every room, you'd never make it to the exit. However, this feat would be possible if one of the doors could open in the opposite direction. Can you find and circle this door?

UK Version

All the doors in the maze below only open when pushed from one direction, as shown.

It is therefore impossible to pass through every room while going through the maze from the entrance to the exit. However, this feat would be possible if one of the doors could open in the opposite direction. Can you find and circle this door?

UK Version

Let's review this puzzle's conditions. You need to make one door open in the opposite direction and you must pass through every room on your way to the exit.

But no one ever said you could only pass through each room once.

US Version

Starting from the IN sign, you'll soon bump into a door that should open the opposite way. So to proceed, one of the first doors you meet will have to open in the opposite direction.

The upper door in the first room and the two doors in the room to the immediate right of the first room open in a direction that keeps you from passing through. One of these three doors is the door you'll need to change.
