Published by Square Enix, the previous 3 Chaos Rings mobile games cost quite an amount as single-player games for the iOS and Android. The 4th installment, Chaos Rings Sigma will buck the trend by going Free-to-Play with a cash item mall.
This essentially means that the new game will be a social, multiplayer one, as opposed to its single-player brothers. A true-blue RPG game, players will meet characters from the past Chaos Rings games as well. Sigma is due for release next year.
