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.
Want to see how far your vocabulary goes? Toggle is free to play.
