Many kids like chess and so many kids also like Sudoku too, so how about combining both chess and Sudoku so that children can think and move numbers like chess but play Sudoku puzzles. Isn’t this a great idea? The best of two worlds.

Mr. Ho has written an article about how his ChessDoku is different from other arithmetic Sudoku and its first page content is as follows, and interested readers can read the rest 9 pages at http://www.scribd.com/doc/136545316/Comparing-Frankho-ChessDoku-to-CalcuDoku-Comparison-between-chess-Sudoku-and-other-calculation-Sudoku
This makes sense.
