Sudoku on:
SudokuPad
Rules:
Chaos Construction: The grid has to be divided into nine regions of orthogonally connected cells. Each row, column and region has to contain the digits 1-9 once each.
Runs: Each uninterrupted extent of cells from a region in a row or column is called a Run. Single-cell Runs are possible. The sum of the digits in a Run is called Run Sum.
Clues: If a small number is given in the bottom-right corner of a cell, it gives the result of adding up the Run Sums of the vertical Run and the horizontal Run this cell is part of. A region may not contain more than one red clue.
Have fun solving!
Example: This is an example picture to clarify Runs and Run Sums. Some Runs are indicated by arrows next to them and the respective Run Sum is given by a red number.
Solution code: The 9 digits from column 6 (top-to-bottom) separated by (+) for borders between regions

What a beautiful puzzle! It's impressive from start to finish, and its break-in is even more ingenious. Although I've made many CCs, this is my favorite one among them.

Having done many cc is a must here. Very deep region building ideas. But as rewarding as it can be. Awesome puzzle.

Brilliant puzzle! Very clever break-in, which took me a bit too long to find, I must admit. The final sudoku was absolutely brutal, which I enjoyed a lot. Thanks!
