A crossword puzzle generator that creates dense puzzles, written in Scala.js.

- Supports fixed crossword puzzle sizes, tries to use the available space most efficiently.
- Supports adding words from a dictionary to complete the puzzle
- Can be printed / exported as PDF (using the browser)
Crossword puzzle generators often create puzzles that need a lot of space, and contain a lot of whitespace (gaps). Sometimes you want a puzzle that fits a given size or space (e.g. for printing), and this is what this generator does.
The crossword puzzle algorithm takes your list of words as input, and then randomly generates many possible puzzles using these words. It then selects the puzzle with the most words (most density).
Web Workers are used to distribute the work of creating puzzles across multiple CPUs.
Crossword dictionaries from the following library are used: https://github.com/fiee/croisee/tree/master/wordlists

- The current algorithm also allows creating puzzles that wrap around the left and right edges of the puzzle. But this is currently not possible on the UI.
