Pokemon Shuffle launched over a week ago, and has launched to quite the bit of attention, even to the state where the Pokemon Company has announced the game has already received one million downloads. Of course I assumed this would happen based on the free to play nature of the game though many didn't think they would so much appeal in this traditional match three puzzler. However because of the number of downloads the Pokemon company has sent a reward via the games check in feature which gives you a complexity -1 item as a present. If you have downloaded the game then you will have received this item. On the positive side the game is surprisingly addictive and enjoyable.
You can get Pokemon Shuffle for free on the eShop.
