In each level of SailorMoon Drops, players have a limited number of moves to complete a specific task, like earning a required number of points or breaking barrier squares by making matches on top of them.
Players make matches by swapping the locations of touching crystals to create lines of three or more matching symbols. When players make matches containing four or more crystals, they create special crystals capable of clearing whole rows or columns of symbols, triggering explosions and more.
Gamers earn up to three stars on each stage, depending on their final score. Users can replay levels to earn any stars they may have missed. However, if players fail to complete a stage before running out of moves, they’ll lose a life. These lives recharge automatically over time, or can be purchased instantly with premium currency.
Levels become more complicated as players progress, but players can use boosters to help them complete stages. One booster, for instance, adds two special crystals to the board at the beginning of a level. Players receive a few boosters for free, and can purchase additional boosters in the game’s store.
