Super Sudoku Spark 16x16

Imagine if we could modify the shape of a  Super Sudoku 16X16. If we look carefully at one puzzle.

We notice that this puzzle is composed of 16 regions of size 4X4, but we could divide the puzzle into 4 parts of 8X8.

By example a Super Sudoku has 4 regions of 8X8 like this.

I was wandering what could happen if we want to insert an another region of size 8X8 into this puzzle. The most obviously method like this

 

produces this puzzle:

Spark 8 5 no 1434
In fact this puzzle is a Spark Sudoku (Rules of Spark Sudoku) with region of 4x4 like the Super Sudoku. This is a Super Sudoku with 5 regions of 8X8 instead of 4 regions. This is my latest creation, I believe that this puzzle will please all puzzlers. I intend soon to create a book about the different variation of the Super Sudoku.
This is the printables files.

This constrain help you to determine which number to put. So I present you one puzzle

Consecutive Super Sudoku 16X16 # 1

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 !.
