With Level-5's celebrated Professor Layton puzzle series due to arrive on Switch imminently with Layton's Mystery Journey: Katrielle and the Millionaires' Conspiracy - Deluxe Edition, a port of the 2017 3DS original, what better time to look back at the Layton clan's back catalogue?

With two trilogies of games featuring Professor Hershel Layton, plus a couple of spin-offs and the upcoming Switch port of the last game which put the Prof's daughter Katrielle front-and-centre, there's no shortage of Layton's particular brand of detective adventuring and gentle puzzle-solving. They're all great games, too, with most featuring high on both our best Nintendo DS games and best Nintendo 3DS games lists.
