Puzzle & Dragons - a game you may justifiably never have heard of - is insanely popular in Japan. Now, you'll have a chance to see what the fuss is all about, as Nintendo is helping to bring the RPG-cum-puzzler to the west.

Whilst originally a free-to-play title, Nintendo is publishing it as a standard 3DS release, although you'll get a fair bit for your money. Not only will you get the standard Puzzle Dragons Z game, but there is also a brand new, exclusive Super Mario Bros. edition.

The game is fairly standard (but hugely addictive) puzzle fare, and you can familiarise yourself with it from the trailer below. The game's out in Europe in May.
