Sailor Moon Drops is a mobile phone game first released in Japan in September 2015, with an English version released in April 2016. It is a match-three puzzle game, where the player has to clear different colored gems from the board in order to achieve the level's objective, similar to games like Candy Crush. Each level allows only a certain level of moves with which to complete the objective; any moves left over at the end will earn bonus points.
The player begins with only Sailor Moon as a character, and as they advance through the levels they will see short episodes that follow the story of the series. Sailor Mercury, Sailor Mars, Sailor Jupiter, and Sailor Venus join Sailor Moon as playable characters during the course of the story, as the Sailor Senshi fight the minions of Queen Beryl, while the civilian forms of the Senshi can be obtained through special time-limited events.
