Word Search Rules & History: Who Invented It

Word & Trivia · Rules & History · July 16, 2026

Word Search feels like it should be an old, timeless puzzle format — but it's actually a fairly recent invention, born in a tiny Oklahoma newspaper less than 60 years ago.

How to Play Word Search

A Word Search puzzle presents a grid filled with letters, along with a list of words hidden somewhere inside that grid. The words can run left to right, right to left, top to bottom, bottom to top, or diagonally in any of those directions, and they often overlap with each other, sharing letters along the way. The player's task is simple: scan the grid and identify each listed word, tracing or highlighting its path of letters from start to finish.

The puzzle is complete once every word on the list has been found. Difficulty typically comes from grid size, the number of words hidden, how many directions are in play, and how cleverly the leftover "filler" letters are chosen to create false starts. On RivalPit, Word Search is timed and scored automatically, so finding words quickly against the clock — solo or against friends — earns you points on the leaderboard.

The History of Word Search

Word Search puzzles are most commonly credited to Norman E. Gibat, who published the first version in 1968 in a small local publication called the Selenby Digest, based in Norman, Oklahoma. Gibat's original puzzle hid 34 Oklahoma town names inside a 20-by-20 letter grid, and readers were invited to find them running in any direction. It's worth noting, honestly, that this is the most widely cited origin story rather than an absolutely airtight one — some informal, similar letter-search puzzles may have circulated earlier in scattered local publications, and a Spanish puzzle creator, Pedro Ocón de Oro, was independently publishing a comparable puzzle called "Sopa de Letras" (Letter Soup) around the same era. Still, Gibat's Selenby Digest puzzle is the version most consistently traced as the origin of the format in English-language puzzling.

The Selenby Digest itself didn't last much longer, closing within a couple of years of publishing that first puzzle, but the format Gibat created had already caught on. Teachers picked it up as a simple classroom tool for vocabulary and spelling practice, and through the 1970s and 1980s, Word Search puzzles spread rapidly into other American newspapers, puzzle magazines, and dedicated puzzle books, becoming one of the most widely reprinted puzzle formats in the country within a generation of its invention.
