Konami’s social game super hit, Dragon Collection, which is close to being the No. 1 game on GREE for a year straight, has passed the four million user mark. Gamebiz reports that the four millionth player registered for the social fantasy card game/RPG on Monday (September 5).
To commemorate the record, Konami set up a “thank you”-campaign for Dragon Collection users: all players logging in between September 5 and 9 enter a lottery and get the chance to win special points (友情pt in Japanese) that can be redeemed in the game.
Dragon Collection is exclusively available on GREE for Japanese feature phones and on GREE for Android and iOS.
