Word Sudoku is a unique puzzle where you need to place a list of given words in a 9x9 grid. The rules are simple - no letter may be repeated in any of the 9 rows or 9 columns or 9 blocks. In this way it is similar to classic Sudoku but the difference is that there are not only nine letters used. Each of the 1000 puzzles is carefully crafted and is solvable by logic alone. There is a hint option available if you get stuck.
