Hidden words. Straight lines. One trusty highlighter.
The word search is younger than it feels: Norman E. Gibat printed the first one in the Selenby Digest, a little classified ads bulletin in Norman, Oklahoma, in 1968 — teachers asked for reprints, and the puzzle photocopied its way into every classroom, waiting room, and activity book on earth. Spain tells a parallel story with Pedro Ocón de Oro's "sopa de letras" (letter soup). Nobody ever owned the name, which is why every puzzle page gets to call it what it is.
This version keeps the activity-book feel — printed capitals on cream paper, translucent marker strokes that stay where you drew them, even the squeak of the felt tip — and adds what print never could: every puzzle is built by placing the words first, so the list is never wrong; the daily page is the same for every player everywhere; and the word lists are hand-picked and kid-safe. Free, no ads, works offline once loaded.
