Professor Layton DLC already on the cartridge

We're sure that many of you inquisitive DS owners out there have spent countless hours with your eyes peeled to your handheld's twin suns, waiting for Nintendo to post the latest downloadable brainteasers for Professor Layton and the Curious Village. This same group of puzzle junkies may be upset to learn that what they're actually downloading is a code to unlock puzzles which are already on the game cartridge -- essentially meaning that there's a set number of puzzles on the game (162, to be exact).

GoNintendo discovered a supposedly complete list of the game's riddles to back up this claim. You can check out every single puzzle featured in the game, and even choose to sneak a peek at every solution as well -- an action we can't help but feel would be frowned upon by the eponymous scholar and his pint-sized associate.
