Liu's introduction to puzzles was reading
Games magazines as a child. In her late 20s, she began solving crosswords, namely the puzzles of
Brendan Emmett Quigley. She regards these events as the main contributors to her love of puzzles. In 2020, Liu was hired as an associate puzzle editor in the
New York Times games department. She is also an assistant editor at the American Values Club Crossword. In 2022, Liu constructed the final round puzzle for the
American Crossword Puzzle Tournament. Liu is the editor of
Connections, a
New York Times game officially introduced in 2023. Since its inception,
Connections has been one of the most popular games on the
New York Times list. Liu constructs boards for the game herself and releases them daily. Despite the large success of her game, Liu has commented that she largely stays away from social media and instead hears people's opinions of her puzzles through her friends and colleagues. ==Personal life==
