The Crossword puzzle maker is used to make simple crossword puzzles. It turns out that good crossword puzzles of the type found in newspapers are fairly hard to generate, and require a pool of lots of words, not all of which are used. This program puts all of the words you specify (no more, no less) into a simple crossword puzzle. Great for vocab and spelling word practice.
