Once players have filled all the cells, they can compare their solutions with the correct answer by selecting the 'view solution' option next to the 'restart' button. This feature not only enhances the gameplay experience by allowing players to learn from their mistakes but also encourages continuous improvement in their problem-solving skills. The game can be a fun way to pass time while engaging the mind in a strategic manner.

The game is part of La Nacion's online offerings and invites players to provide feedback or suggestions via email or WhatsApp, demonstrating the outlet's commitment to enhancing user experience.
