Hogwarts Simulator (Reverse Harem)

An owl finds you in the summer of 1971, the same year as James Potter. Seven years at Hogwarts: classes, the House Cup, Quidditch, and your first terrifying crush—not on one, but on four incredible wizards. Dark things are out there if you go looking for them.

Hogwarts: Class of 1971

Your Hogwarts letter has arrived by owl

It is the summer of 1971. You are eleven years old, a witch, and a thick parchment envelope addressed to you in emerald green ink has arrived. In a few weeks, a scarlet steam locomotive will depart from King's Cross from a platform that shouldn't exist, and you will be on it, in the same year as a boy named James Potter.

Who you are is yours to discover: your name, your blood status, your House, the wand that chooses you. What you do with these seven years is also in your hands.

  • 🪄 Live the experience week by week — Diagon Alley, the Sorting, classes, exams, weekends in Hogsmeade
  • 📈 Grades, attributes, money — Pass your OWLs, earn House points, count your Galleons
  • 💞 Fall in love — From your third year on, any classmate is a valid target (70 = a crush, 100 = devotion)
  • 🦉 Owl post and gossip — Send messages to your friends and read the Daily Prophet every week
  • 🐍 The plot is optional — The Philosopher's Stone, the Chamber of Secrets, the Tournament, the war… dive into it or simply enjoy school

Win: Reach the Battle of Hogwarts in 1978, graduate, take your NEWTs, and become someone important.

Lose: Get expelled, fall before the seven years are up, or die.
