O-OO puzzle: can you crack this Sunday brainteaser?

Show summary Hide summary

Every Sunday, word lovers get a fresh brainteaser that blends language play with a dash of whimsy. This week’s puzzle asks you to turn a single-O word into a new word by doubling that O. It’s simple to state and tricky to execute, the kind of challenge that rewards close reading and lateral thinking.

How the double‑O rule works and an example

The game gives you sentences with two blanks. Fill the first blank with a word that contains a single letter O. If you double that O, you form a different word that completes the second blank. Use that pairing to finish the sentence.
