You get a starting word, a target shape, and a hint. Example: CREAM +4, -3 _ _ _ _ _ _ "Morning beverage" ... did you guess COFFEE? You got this. Color clues guide you as you type: โ€ข Green โ€” right letter, right spot โ€ข Yellow โ€” right letter, wrong spot โ€ข Red โ€” was in the starting word, but not the answer โ€ข Gray โ€” not in the answer at all That's the whole game. No timers. No leaderboards. No notifications you didn't ask for. Just one puzzle a day, fewer letters than you'd think, and the satisfaction of seeing the word click into place. What's inside โ€ข A new puzzle every day โ€ข Streaks, history, and share-your-result-in-emoji โ€ข Crews โ€” small private groups for friends and coworkers, with a daily group view of who's solved what โ€ข Optional accounts (sign in via magic link; no password needed) โ€ข Daily-puzzle-by-email if you want it; one-click unsubscribe โ€ข Anonymous play if you don't want an account โ€” your history lives on the device Privacy We don't track you across other apps.
