Find a good Harry Potter game, if possible for free or otherwise as cheap as possible. It should be really adventure-like so that it is as exciting as reading the books or watching the film (for the first time).
Stop so really well done. For laptop or mobile phone.
Do you know something very good?
The best is Hogwarts Mystery for the phone.
For the PC it would be the original games from the film.
For mobile phones:
Hogwarts Mystery, Wizzards Unite, Harry Potter Puzzles and Spell
A new game will be released next year for PC and consoles: Hogwarts Legacy
