Alphadoku Puzzles. Alphadoku puzzles are similar to Sudoku puzzles but they use letters instead of numbers. Each puzzle has nine letters to place in the grid so none of them repeat in any row, column, or block. The fun comes when one of the rows, columns, or diagonals spells out a word. The title of the puzzle holds a clue as to what it will be.
