Number Lock is a puzzle in Professor Layton and the Curious Village.

Puzzle

The door in front of you has an odd lock mounted on the front. The only way to unlock this strange contraption is to place small tiles labeled from one to nine in its slots. The lock will open when the numbers on the lock equal the same number when multiplied vertically and horizontally.

There are nine tiles, but the lock only has seven slots, so you won't need two tiles.

Can you open the lock?

Hints

There are multiple correct answers, so the best thing to do is just work patiently until you find a solution.

For those of us without patience, here's a more obvious hint: you can eliminate the five tile.

The five tile isn't used in your answer, nor is the seven tile.

Now that you know the seven tiles you need to work with, see if you can find the answer.

When you multiply each row of numbers, they should all equal 72.

If you still feel like you could use a hint, here's one more. Place the two tile in the center slot of the lock.

This is a hard puzzle, it's true. Keep at it.

Correct

That's right!

As long as all three of your combinations equal out to 72, you've got the right answer.

The diagram above shows one of many possible correct configurations.

The only tiles you can't use in your answer are the five and seven tiles.
