The three games are:
- Mystery Legends: Sleepy Hollow - The first game of the series based on The Legend of Sleepy Hollow, your mission is to search every location in Sleepy Hollow, solve puzzles and find scattered items, and uncover the terible fates of the well-known residents of Sleepy Hollow. Be vigilant, though, for the Headless Horseman is looking for a new head to take.
- Mystery Legends: The Phantom of the Opera - The second game of the series based on The Phantom of the Opera. Taking place after the events of the book, the story is experienced through Evelina, the daughter of Christine Daae and Raoul de Chagny, who is kidnapped by the Phantom - who it turned out is alive and still obsessive - and has to find a way to escape the abandoned opera house.
- Mystery Legends: Beauty and the Beast - The third game of the series is based on the classic fairy tale Beauty and the Beast. Taking place after the tale, Belle discovers something amiss when her beloved is turned to stone and figures out the enchantress who had cursed him had something to do with it. Now, she must venture out to save her love again - and this time, deal with the enchantress personally.
