Pika! Pika pi-pi-pi-pika!! Pokémon Shuffle has hit Nintendo’s eShop in Europe. A free to play match three puzzle game with a structure similar to Disney puzzle games such as Frozen Free-Fall.
You start with five hearts and can play as long as you want until you lose all five, at which point you will need to wait until they replenish. Either that, or you will be able to micro-transact your way back into the fold.
Unlike other free to play games though, streetpassing others will give you the opportunity to earn bonus jewels which will alleviate the microtansactions slightly.
Worth a download I reckon.
