Seven Towers is a puzzle in Professor Layton and the Last Specter.

Puzzle

US Version

Seven towers stand on a waterway, each connected by a bridge. One day the towers were tested to see which ones could be reached after crossing exactly six bridges, starting from shore A or shore B. It was discovered that all of the towers could be reached in this way except one.

Keeping in mind that the same bridge cannot be crossed twice in one trip, which tower cannot be reached after crossing over exactly six bridges?

US Version

You can reach the bottom-left and bottom-right towers in exactly six moves, so neither of those is the answer.

UK Version

You can reach the bottom-left and bottom-right towers in exactly six moves. Thus, neither of those is the answer.

That leaves only three towers: the top left, the top right, and the one in the middle.

UK Version

You can also reach the towers on the far-left and far-right in exactly six moves.

That leaves only three towers: the top-left, the top-right and the central.

US Version

The tower in the middle can be reached in exactly six moves. That leaves only the towers on the top right and the top left.

UK Version

The tower in the centre can be reached in exactly six moves. That leaves only the towers in the top-right and the top-left.
