Toggle: The Game

Master your prefixes and suffixes!

Toggle is a word game for people who love language — not just long words, but the building blocks behind them. Each puzzle gives you a board of prefixes, roots, and suffixes. Your job: mix and match them into the longest, highest-scoring words you can find before the clock runs out. It's fast, satisfying, and quietly teaches you more about English than a decade of crosswords. Play: Trace paths across morpheme tiles to form words. Every puzzle is different. Review: After each game, see every word the board contained — the ones you found and the ones you missed — with definitions. Miss a word twice? You'll start to remember it. Challenge: Share a link or scan a QR code to challenge anyone, anywhere to the same puzzle. Play head-to-head, compare scores, settle debates. Climb: Daily, weekly, and all-time leaderboards track your rating as you improve. Rise from Novice to Apprentice to beyond. Learn: Toggle's dictionary spans over 100,000 words across medicine, science, philosophy, and the humanities. The more you play, the more you know.
