The Royal Romances and the Unsolved Case is a series of mobile games that uses a new format and is separated into multiple episodes.
They both come in the standard (CE) and a free-to-play version.
You can distinguish them by the clapperboard symbol in the corner of the icon. The free-to-play version of the game also has a blue frame around it.
Since this series is separated into multiple episodes, they are shorter than the regular full-length game.
Passing episode by episode, you will learn the whole new story adventure.
Also, the player has the ability to influence the storyline of the game and find out several endings of the game depending on your choices!
