The hexadoku is a 16x16 grid whereby the rules for solving the puzzle are the same as those for solving a 9x9 sudoku grid.
In a Sudoku as in a hexadoku, the numbers are used for conventional purposes only. There is no mathematical relation between squares. All symbolic distinctions: symbols, letters, numbers, shapes, colors can be applied without changing the rules of the game.
In order to save screen space and to simplify entry, the 16 possible numbers are symbolized here by the following hexadecimal digits: 0,1,2,3,4,5,6,7,8,9,A,B,C,D,E,F.
The hexadecimal system is a numeral system with a base of 16, using Arabic numerals to represent the first ten numbers (0-9) and the letters A-F for the other six digits. The hexadecimal system is useful in computer science because it is easier to map the hexadecimal system to the binary than the decimal system.
