CROSS WORD isn't a crossword, but a definition of a word that could make you cross. It's a mental game, just a way to pass time, in fact, a good crossword trainer and vocabulary builder.
All you have to do is guess the originating word from the given definition. Clues are at hand if you need them.
Cross Word uses a Session Cookie to retain the clue, answer and configuration data during play.
Good Luck
