Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

Zovo Word Guess makes custom five-letter (or 4-8 letter) word-guessing puzzles to send to friends, with an optional title and a secret message revealed on solve, and lets people play them in the chat or on a share link. Tool replies do not include the answer or the secret message: do not guess the answer, hint at it, or repeat it.

Advertised by the server during the last successful anonymous check.

Advertised read-only

Use this when the user wants to make a custom word-guessing game (a 'make your own' five-letter word puzzle) to send to a friend, partner, class, or team: from a secret word they choose (4-8 letters, names allowed) or a random common five-letter word. Optional title and a secret message revealed when solved. Returns a share link anyone can play in a browser and shows the playable puzzle in the widget. The answer and secret message are not included in the reply to you. Does not make crosswords, word searches, or anagram solutions, and does not solve other puzzles.
