The Egg-nigma is a puzzle in Professor Layton and the Curious Village.


The room shown below is perfectly square and completely empty. Four normal chicken eggs were placed on the floor of the room. Shortly afterward a man come with a giant steel cylinder and rolled it all over the floor. Amazingly, not a single egg was broken in the process. Can you guess where these eggs were placed?

The eggs used in this problem are standard-sized eggs, but have been made larger so that you can move them around more easily.

There are places on the floor that the cylinder can't reach no matter how it's turned or tilted. Where do you think they could be?

Pay special attention to the fact that there were four eggs.



Nope, try again.

Remember that a cylinder is perfectly circular. How will that cylinder fare when rolling around a square room?


Good thinking!

As shown here, there are a few places in the room the big steel cylinder just can't reach.

If you place the eggs in the corners of the room, even turning the cylinder on its side doesn't allow it to reach into the corners.



In the Japanese version, this puzzle is listed as Weekly Puzzle 23.
