Circle of Mana

Circle of Mana was a short-lived trading-card simulator and a spin-off game in the Mana series. It was released on March 5, 2013 for the Japanese social gaming network GREE on iOS and Android devices. Though it brought together a number of characters from the series as it existed at the time, it was only active for two-and-a-half years. The game closed September 2015, for unspecified reasons.
