To celebrate the forthcoming release of Professor Layton and the Miracle Mask (or Mask of Miracle, depending on where in the world you happen to be) Nintendo has created a UK-based Facebook quiz which allows you to test your knowledge of Layton's world.

If you're clever enough to solve all of the tests, you'll be entered into a random prize draw where you could win a selection of Layton-themed goodies, as this official blurb reveals:

Could you be the ultimate Layton sidekick? If you have the tenacity and knowledge to succeed in all five tests at Gressenheller University (where Professor Layton himself lectures) and attain the remarkable status of Professor of Puzzling, you will have the option to enter a random prize draw.

Five lucky winners selected at random will win a Professor Layton pack which will include a Layton plush, a copy of Professor Layton and the Miracle Mask, a 3DS XL and Professor Layton & The Eternal Diva: The Movie. You should also look out for small digital rewards along your puzzling journey.

Sadly for those outside of the British Isles, this competition is limited to UK Facebook users, but if Nintendo of America decides to run something similar, we'll let you know.
