Generistik is a free tool for designing Finnish crossword puzzles. This tool automatically fills words to a crossword grid and therefore frees the designer from the most difficult task of the crossword creation process. Unlike many other crossword filling tools, Generistik does not require designing of the whole crossword template before starting the filling algorithm. Instead, the filling algorithm runs continuously on the background and lets the user to make changes to the structure of the crossword at any time.
