Nintendo’s free-to-play match-three puzzle 3DS game Pokemon Shuffle has now crossed 1 million downloads. The game was announced in January and launched through the Nintendo eShop in February.

Pokemon Shuffle is similar in presentation to Bejeweled and Candy Crush, but it replaces the gems with faces of popular Pokemon such as Bulbasaur and Charmander, among others.

Players must line these up in rows of three for them to disappear. The twist on the match-three format is that a player will have a limited number of moves available to create a certain number of matches, meaning that in some cases thinking ahead is required to chain combos together.

In Pokemon Shuffle, players can also level their characters so that they can do more damage. Certain Pokemon can even Mega Evolve, just as they can in Pokemon Omega Ruby/Alpha Sapphire.
