Seeing as I've never been able to play the iOS version of Puzzle & Dragons, I've been patiently waiting for the 3DS version to come out for over a year after its initial announcement. Fast-forward to May 22, 2015, the game is now out over here along with another game. Specifically, Puzzle & Dragons Z + Puzzle & Dragons: Super Mario Bros. Edition is sold in North America and Europe as one package (in Japan, those two were separate and released on different dates).
I highly recommend it if you're tired of those traditional "match three" puzzle games and want an RPG twist. I guess you can say it's like Pokémon.
Oh, and if you're unsure about getting the game, there's an eShop demo available. It only allows you to play the SMB side, but the gameplay is pretty much the same for both sides.
