The puzzle is waiting. We update it every single week. It is not just a random collection of words. It is a themed challenge built directly from our favorite HowStuffWorks deep dives. Think of it as trivia for people who actually want to know why the sky is blue, not just that it is.
Clues are brainy. They require a specific kind of focus. You will need to dig into the mechanics of everyday life. Why does ice cream freeze? How do jet engines survive extreme heat? These are the questions that end up in the grid.
If you want the first crack at this week’s puzzle, there is one move you need to make.
