The difference of Sudoku X from the classic Sudoku is that the Sudoku X has an additional constraint : the number from 1 to 9 must appear once in each diagonal (grey cells). I present you two instances of this puzzle: one with a regular Sidoku and the other with a Super Sudoku 16X16.

This is two Sudoku Diagonal puzzles. This kind of puzzles is similar with classical Sudoku with a little supplementary twist: in each 2 diagonals (gray cells) the numbers from 1 to 9 ( or 1 to 16 in the case of the Super Sudoku) must appear only once. The first puzzle is a classic Sudoku with the two diagonals.

To continue with variation about the Super Sudoku 16x16. One that is obvious is the Sudoku even/odd, each grayed cell has an even number (2,4,6...) and on the other hand each normal cell (white cell) has odd number (1,3,5 ..). This constrain help you to determine which number to put. So I present you one puzzle

Directly from the oven, still steaming, I present you a different flavor of the Super Sudoku: the consecutive Super Sudoku. In addition to the regular rules, each cell having a mark (white bar) must have a number that is consecutive to the other cell sharing the mark. This means that the other number in the other cell must have a difference of 1 with the original cell. By example if a cell has a 4 and has a mark then the adjacent cell (the cell who share the mark) should have either 3 or 5. This rule also implies that if no mark appears between two cells then the difference of the two numbers is greater than one. Enough discussion, try it by yourself !.
