One Valid Word

A daily word game with exactly one answer.

Swap letters until the word clicks,
in the app or right on your Home Screen.

Free, with no ads.

Small, fair and forgiving

A Daily of six letters and a Daily Mini of four, the same for everyone, every day. Then as many Free Play words as you like.

Exactly one answer

Every word is one whose letters spell no other common word. You’ll never lose to a word list. Everyone gets the same puzzle and the same par, so “I did it in four” means something.

Also on your Home Screen

Add the Up Next widget and the day’s puzzles wait on your Home Screen: the Daily, then the Mini, then a fresh Free Play word whenever you have a minute. It shares its board with the app, so open the app whenever you want a hint.

A streak that forgives

Rest days cover a missed day on their own: you start with one and earn another every week you play. Missed yesterday? Your streak didn’t. It follows you between iPhone and iPad, too.

How it plays

Tap two letters, or drag one onto another, to swap them. Par is the fewest swaps that solve the puzzle.

Pin what you’re sure ofDouble-tap a letter to pin it down, so it can’t move by mistake. It’s only your guess, and it costs nothing.

RevealA hint turns a tile over to show the letter that belongs there. Swap it in and pin it.

SwapA hint shakes two letters that would both be in place if you swapped them. Hints are earned by playing.

Reminders stay off unless you ask for them, skip days you’ve already played, and fade away if you take a break.
