for (American English-speaking) word puzzle and sudoku fans ...
I've been trying for a while to combine sudoku with a word puzzle. here's my best effort to date. this sudoku uses 9 letters instead of numbers - those 9 letters form a number of words, as suggested by the crossword clues. solve the crossword - solve the sudoku.
