What's My Word was first published in 1972 by Gamut of Games under the name My Word. This classic game has been called "the best two-player word game ever invented" by more than one critic. As easy-to-learn and challenging-to-play fast-moving game of word deduction, What's My Word? is a two-person race to detect each other's secret word by piecing together clue after clue. Great for travel, play it anywhere.
