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.

Have fun solving!
