Dark Summoner, a card battle game from Japanese game developer A-Team (TYO:3662), has broken through the 5 million worldwide downloads milestone. The iOS game has been around for about a year, and the Android version launched this past summer.

According to social games expert Serkan Toto, the game has seen some impressive profitability as well. The English version of the title has managed to stay in the 100 top grossing app ranks for iOS, and on Google Play both the English and Japanese versions have been in the top 10 or 15 since their release.

A commercial featuring AKB48’s Haruna Kojima is currently in heavy rotation [1] on television in Japan promoting an in-game campaign that runs until February 15th allowing you to get special monster cards. You can check out the commercial below. They also have a ‘making of’ video online, if you’re into that sort of thing.

I’ve only just begun playing this game, but if you enjoy the card battle genre you’ll probably like this one too. It takes a little while to get into, but the process of collecting rare monster cards and sacrificing other cards to improve them is pretty addicting. I hope to give it a short video review once I spend a little more time with it. In the meantime, if you have any tips or advice for the game, feel free to share it in the comments.
