Super Soduku

Getting tired of those plain 3 x 3 grid (81 squares) Suduko puzzles? The Independent ( A UK Newspaper ) has released a version in its weekend edition of a 4 x 4 grid (256 squares), called the Super Soduku.
Because we run out of numbers at 9, it uses the computer number base hexadecimal, which uses the letters a - f to signify 10 - 15.
