Letterbox Messages turns any phrase into a scrambled-tile puzzle you send right inside Messages - your friend taps it and unscrambles the letters to reveal what you wrote. HOW IT WORKS • Type any message - it gets jumbled into letter tiles. • Send it in the chat. Your friend taps the bubble and unscrambles it. • Or pick from a starter set of famous quotes, movie lines, and song titles. NO CATCH • Completely free. • No account, no sign-up - works right in Messages. • Nothing leaves your device: the puzzle travels inside the message itself. Love it? The full Letterbox game has 300+ hand-built puzzles across history, film, and music - each with the story behind the quote - plus a custom builder and iCloud sync.
