Harry Potter: Quidditch Champions

The Hogwarts Hero achievement requires no online matches to be played.

The Hogwarts Quidditch House Cup can be accessed through the menu by going to Play > Press A > Campaign > Hogwarts Quidditch House Cup. I believe you must have completed The Weasley Burrow Garden Cup (tutorials) to access this Cup, although I could use confirmation on this.

This Cup contains three placement matches, and two tournament matches. You will select which Hogwarts house you want to play as, and then play one placement match against each of the other three houses. You do not have to win these matches. The placement matches keep a tally of total points scored, and after your three matches will use the total points scored for all four teams to determine seeding in the tournament. All four houses qualify for the tournament, so don’t stress about winning the placement matches.

After the three placement matches, you will then play elimination tournament matches, which you must win. This is a small, two round tournament, so you will only need to win two matches in order to win the Cup. If you’re struggling to win matches, try restarting the tournament and selecting a lower difficulty.

Once you win both tournament matches, you win the Hogwarts Quidditch House Cup and the achievement will unlock!

I hope this helps!
