Crossword Generator

The Crossword Generator creates crossword grids from a word list for printable or digital use. It handles word placement, orientation, and numbering, producing a data-rich grid and corresponding clues. Users supply grid_size, a word list, optional clues or a theme, and receive a structured grid suitable for printing or import into puzzle apps. Conceptually, the tool treats placement as a constraint satisfaction problem and uses backtracking to fit words while maximizing cross-letters. It outputs a 2D grid, a numbered clue set, and a portable data object for downstream workflows. The approach supports educators, content creators, and learners who need repeatable puzzle content with consistent formatting and easy export. Unique value lies in reproducible layouts, configurable constraints, and clean data exports for automated workflows. Core features include automated word placement, optional automatic clue placeholders, theme support, and multiple export formats. Use cases include classroom worksheets, online quizzes, vocabulary practice, and exam review tasks.
