As has become a Christmas tradition, Joe Merrick of Pokémon fansite Serebii has created a new edition of the site's annual Advent crossword. There are 400 clues to figure out in total, and you can choose to either fill out the entire thing online or print it out to do it by hand.

Just like in previous years, we should really stress that this is a challenge designed for those with a truly deep love of the series. We consider ourselves pretty knowledgeable on the subject, but even we're struggling with plenty of the crossword's tougher clues.

Think you have what it takes? Then try it out using the link below and let us know how you get on in the comments.

Good luck!
