We’ve gone mad for puzzles. This makes sense – it’s reassuring to have answers in these perplexing times

Maybe you’ve noticed it too. Everyone seems to have become fixated on puzzle games. In the morning, over coffee, I play Word Wheel on the Guardian app. Over lunch, colleagues compare notes on Tradle, the game where you guess a country from its exports. Which place exports about 45% fish and 50% crustaceans? Greenland. Another friend can’t fall asleep without her nightly Sudoku ritual.

The online puzzle craze took off during the Covid pandemic, and it shows no sign of slowing down. New York Times subscribers now spend more time playing puzzles on the app than reading the news. Sales of quiz books hit a record last year, up 24% from 2024.
