Market Shortcut is a puzzle in Professor Layton and the Last Specter. The puzzle must be solved in order to progress the story.

Puzzle

US Version

There are several roads crisscrossing the marketplace. From the entrance, you want to pass over every section of road and reach the exit without ever taking the same portion of road twice.

Draw a single straight line showing the road that would need to be constructed to make this possible. The new road can only start and end at existing intersections or corners.

Don't forget about the Memo function!

You can use it to trace a route along the streets and gain a better understanding of the problem.

DOn't forget about the Memo Function!

You can use it to trace a route along the streets and gain a better understanding of the problem.

The road you will need to create is a single diagonal line connecting two intersections.

This is a classic single-traversal puzzle. In order to draw a route that passes through every stretch of road exactly once, there must be an even number of roads extending from each intersection.

Search for intersections that have an odd number of roads extending from them. There should be two such points.

US Version

How can you add a single line that will result in both intersections having an even number of roads?

UK Version

Now, how can you add a single line that will result in both intersections having an even number of roads?


Solution

Incorrect

Too bad!

This is a tough one, isn't it? Don't give up!

Correct

Correct!

What a convoluted path to traverse! If it only went directly from the entrance to the exit, you wouldn't have to take so many detours!
