Logic Masters Deutschland e.V.

This idea evolved into something quite strange, but I believe you will find some interesting stuff hidden inside :) Good luck, and enjoy!

Rules:

Chaos Construction: Place the digits 1 to 6 in every row, column, and region. Each region is a set of six orthogonally-connected cells that must be determined while solving.

The Constriction—Region Vision Line:

• Draw a single line through the center of some cells that moves horizontally or vertically. The line does not branch or visit any cell more than once. One end of the line is given as a white circle.
• Between adjacent cells on the line, draw a region border.
• A digit on the line indicates the number of cells seen in all orthogonal directions combined (including the cell with the digit). Region borders obstruct vision.
• The line must visit every region at least once (the line may move in and out of regions as many times as necessary).

External Clues—Sum of Line Cells: Clues outside the grid give the sum of all digits on the line in the corresponding row or column. A sum of 0 is allowed in clued rows or columns.

Example: Below is 5x5 example of the rules interacting (and not necessarily an actual puzzle).
