Scrutinized Screws (Scrutinised Screws in the UK version) is a puzzle in Professor Layton and the Unwound Future. The puzzle must be solved in order to progress the story.


Only one of the six screws shown below, A, B, C, D, E, or F, will fit properly into the threaded hole. The width of the hole matches the thickness of all the screws, so don't worry about that.

Your only tool is a flathead screwdriver. Now, hurry! You don't have much time.

Circle the correct screw, and tap Submit.


Click a Tab to reveal the Hint.

Pay attention to the direction of the threads on the screws and on the hole.

Screw C won't go anywhere no matter how much you turn it! So, cross that one off the list of possible answers.

Screw B can't be turned with any tool, and Screw F can't be turned with a flathead screwdriver. So cross those tow options off the list as well.

Screw A is threaded in the opposite direction of the hole, so it can't be the answer. That leaves only two possible choices. Take one last look, and you should have this in the bag.



Too bad!

Take another look, and try again.


That's it!

Now, hurry and get the car moving!
