Today’s puzzle explained
How the September 12 board is organized
The verified source identifies Wyna Liu as editor. Difficulty references here follow the official yellow, green, blue, and purple order without making claims about editorial intent.
Why the board is deceptive
The yellow and green groups use direct category relationships, while the blue group asks which four listed things share an observable action.
The purple set is a blank-style phrase group: each answer forms a supported expression when placed before the same word, ALERT.
