Hexadoku - The Original Elektorized Sudoku 

Traditionally, the last page of Elektor magazine is reserved for our puzzle with an electronics slant: welcome to Hexadoku! Don't miss out on your chance to win special prizes by solving the Hexadoku puzzle. 

The Hexadoku puzzle employs numbers in the hexadecimal range 0 through F. In the diagram composed of 16 × 16 boxes, enter numbers such that all hexadecimal numbers 0 through F (that’s 0-9 and A-F) occur once only in each row, once in each column and in each of the 4×4 boxes (marked by the thicker black lines). A number of clues are given in the puzzle and these determine the start situation.
