HEXSudoku - Sudoku 16x16

What is a difference

Classical sudoku has got 9 row, 9 columns, 9 box (eachone with 9 patches - 3x3) and we support number 1-9. HEXSudoku (HEX - hexadecimal - 16) has got 16 row, 16 columns,

16 box (eachone 16 patches - 4x4) and we support number 0; 1; 2; 3; 4; 5; 6; 7; 8; 9; A; B; C; D; E; F, then digits of hexadecimal system. There are digits of decimal system except 0 in classical sudoku. Generally Sudoku has got the main number (classical: 9; HEX: 16) N². N is natural number (integral number larger than 0). Classical sudoku: 3²(9), HEXSudoku: 4²(16). The sum of total patches is this number power of two (rows x columns) - classical sudoku 9² - 81, HEXSudoku 16² - 256. And how many times more patches has HEXSudoku got in fact? Simply 256/81 ≈ 3,1604938.

How to solve

I should perhaps remind the basic axiom of sudoku yet.Every row, column and every 9 (16) boxs, which sudoku is divided in, must contain exactly 1x each digit (HEXSudoku: 0-F; classical sudoku: 1-9). So there will be 16x0; 16x1; 16x2;...;16xF in HEXSudoku.

There are two basic ways: This number can be only here; or Only this number can be here. There exist many other methods and books and web pages expositive these methods as well.

Theory

Abstractedly Sudoku needn't include numbers, but for example states Europe (e.g. flags) or anything other. But it could be also sudoku with Roman numerals (I; II; III; IV; V; VI;..) or with Greek alphabet (α;β;γ;δ;...).

HEXSudoku can be as easy as the easiest difficulty of norm. sudoku, but also more difficult than the most difficult scale of norm. sudoku. But in my opinion definitely more interesting.
