It hasn't even officially launched yet -- the game is slated for release later in 2018 -- but the Harry Potter: Hogwarts Mystery mobile game has already made a mysterious appearance in Google's Play Store and is soft-launching in a handful of regions.

To build excitement, the game also has an official website, where you can uncover a few more details about the game and sign up to learn even more, and be notified when it's released.

Here's what we know so far: The roleplaying game is set some time in the 11 years after Harry's birth but before he attends the Hogwarts School of Witchcraft and Wizardry. It opens with your chosen, customizable character's acceptance letter to Hogwarts, signed by Professor Minerva McGonagall.

To progress through the school year, you complete quests, learn spells and potions, and interact with objects to earn rewards and XP. For example, when the game begins, you find yourself in London's Diagon Alley. You make the rounds of various shops located on cobblestone streets, gathering items you will need as a first-year student, including your books and wand.

As you play, you meet familiar and new wizarding characters and learn a bit about your character's backstory. By answering questions and making choices, you shape your own character. And, of course, you get your turn wearing the Sorting Hat and can pick which house to join: Gryffindor, Hufflepuff, Ravenclaw, or Slytherin. You also work toward winning the House Cup by earning -- or losing -- house points. And as you play, you come across clues and hints that will help you solve the Hogwarts mystery.

From what we've seen, the game looks interesting, with an attractive art style and an engaging story line.

Harry Potter: Hogwarts Mystery is currently in beta and will be released for Android and iOS later this year. The game is available now in a handful of regions. It is developed by JamCity, Warner Bros. Interactive Entertainment's new Portkey Games label.
