It's one of the most profitable games Japan has ever produced. It features cute monsters battling one another in colourful explosions of violence, and it's become this year's interactive obsession for many handheld gamers.

Believe it or not, we're not talking about Pokemon X & Y. The creature battler in question is none other than match-three hit Puzzle & Dragons. After a lengthy wait, it has finally come to the UK App Store, thereby giving us western-types a chance to see what all the fuss is about. 

Developed by GungHo, this colour-matching cash cow charges you with gathering a team of collectible beasties together, before heading into a dungeon and facing the nasties inside.

To attack, you match up coloured symbols on a grid. The more colours you match, the more powerful your attacks will be. You can also evolve your creatures Pokemon-style, until you're the master of your very own unstoppable horde of giant pink lizards.

We're going to take a look at this one over the weekend, and throw up a review next week. If you're a UK resident and can't wait to get in on the action, you can download Puzzle & Dragons for free right now.
