EclipseCrossword is a free Windows application from Green Eclipse that helps users create custom crossword puzzles quickly and easily. Users provide their own words and clues, and the software turns them into a puzzle in seconds. Finished crosswords can be printed or shared online, with files also available for use in Word or other publishing software.

The application is designed for a wide range of purposes. Teachers and parents can use tailored puzzles to review vocabulary and spelling, introduce new terms, and quiz students. Organizations can create puzzles for newsletters, while website owners can add interactive content to engage visitors.

EclipseCrossword says its website puzzles do not fill users’ sites with ads or track their visitors. The software is described as completely free, rather than a trial version, and has been downloaded millions of times. The site also offers a product tour, examples of puzzles, user comments, help information, and a donation option.

EclipseCrossword focuses on making personalized crossword creation accessible for learning, publishing, and entertainment
