How to Play Acrostic Crossword
Play 30 original acrostic word puzzles directly in your browser. Solve definitions, connect numbered letters and uncover short messages, with optional hints and no account or download. Your progress stays on this device, separately for each language.
2. Place the letters.
Each letter fills the matching numbered position in the hidden message.
3. Reveal the phrase.
Use the emerging message to solve the remaining clues. Every correct letter counts!
Acrostic Crossword Rules
- Every number identifies one specific position in the hidden phrase. Two A letters can have different numbers; changing one does not change every A.
- Letters flow both ways: edit a clue or the hidden message and its matching position updates. You may change any draft letter. Hint reveals and protects one correct letter in the selected clue.
- Each word is checked automatically as soon as all its letters are filled. Incorrect letters are marked so you can correct them. A correct answer moves you to the next unfinished word. Undo reverses a manual edit. Finish every letter correctly to unlock the next level.
- There are no lives, forced countdowns or paid hints. The timer records active play only. Restart clears this attempt; your completed levels and best records remain.
Tips & Strategy
- Start with a definition you recognize. One answer can place letters in several different words.
- Look at word lengths and common endings in the hidden message. Use those patterns to work back to an uncertain clue.
- Finish a word and use the automatic feedback before building on it. If you are stuck, select that clue and reveal just one letter with Hint.
30 Levels, One Discovery at a Time
Start with three short clues, then work through six themed sets of five puzzles. Later messages are longer and use more varied vocabulary. Complete levels in order, replay unlocked puzzles and try to improve your best time or finish without hints. Replays use the same puzzle, not a newly generated one.

Frequently Asked Questions
Is this acrostic puzzle free to play?
Yes. All 30 levels in each language, hints and replays are free. No registration or download is required.
Is this the official Crostic Crossword game?
No. OnlinePuzzle is an independent Crostic-style browser puzzle with its own levels. It is not affiliated with Severex, Crostic or Figgerits and does not provide answers to their levels.
Can I play on my phone or with a keyboard?
Yes. Tap the on-screen keys or use a physical keyboard. Arrow keys move between boxes. Completed words are checked automatically.
Does my progress save?
Progress, completed levels, sound settings and best records save in this browser when local storage is available. Each language has a separate save. Clearing browser data removes it; progress does not sync between devices.
What do the numbers mean?
Each number points to one letter position in the hidden phrase. It is a position mapping, not a global substitution cipher. Guessing one letter updates only its matching numbered box.
Do these puzzles spell an author’s name?
No. This version focuses on definitions and hidden phrases. The first letters of clue answers do not encode an author, and messages are not presented as attributed quotations.
