Wordoku puzzlesMy database includes 200 puzzles for the moment and I'm constantly generating more.
Rules: Fill in the grid so that every row, every column, and every box contains the letters named under the board. The grey cells contains vowels and the white contains consonants. The diagonal will contain an english word as in ordinary wordokus, but is not marked. There is only 1 solution for each puzzle.
