Quizzja is a multilingual crossword game. Solve a fresh daily puzzle, work through themed categories, and pick up where you left off on any device — in your language.

How Quizzja is funded
The free game can include Google advertising on supported apps, subject to your privacy choices. Advertising and optional usage measurement are separate choices; you can decline them and still play. Open You → Privacy and data → Cookie settings on the Web, or the available Ad privacy choices in the mobile app, to manage advertising.
Where offered, Lifetime Pro is a one-time purchase that removes ads and gives unlimited hints. It does not unlock paid puzzle packs. See our Privacy Policy, Cookie Policy, and Terms of Service for the data, advertising, and purchase details.
Credits
All Quizzja crosswords are hand curated. People select and review the words and clues for each language. Software assembles grids from this curated content.
If a clue seems unclear or incorrect, send the puzzle title, language and clue number to support@quizzja.com, or use Report a bug in the app.
