Constructive Chaos

Rules:

1. Standard sudoku:

Place the digits one through nine in every row column and region.

2. 10 sum lines:

Grey lines contain one or more contigous groupings of digits that sum to ten.

3. Chaos Construction:

Construct nine different regions that every row, column, and region has the digits one through nine once each. Each region will contain nine orthoganally connected cells.

4. Chess Sum cells:

A cell with a number in its top-left corner is a Chess Sums cell. The number in the top-left corner indicates the amount of Chess Sums satisfied by the digit in that cell. A digit in a Chess Sums cell gives one or more of the following:

-The sum of all digits that share its region and are a king's move away.

-The sum of all digits that share its region and are a knight's move away.

-The sum of all digits that share its region and are a bishop's move away.

**Note** A different region could separate a bishop's move.

Ex. A chess sum of "3" with a nine placed in the cell indicates there is three groupings of cells they are a kings move, bishops move, and a knights move away from the chess sum clue. Each group of cells sum to nine.
