Making word searches more challenging
- Choose Hard. Words can read in eight directions, and backward words are the ones most people miss.
- Turn on the timer. It counts only while you’re playing and the tab is visible, so your time is honest. It’s off by default.
- Skip the hints. Hints show the first letter of one word; the count is shown on your result.
- Make your own. Use a list from your field — wine regions, bird species, chess openings — in the word search maker.
