Draw a diagonal line in each square of the grid. Numbers at some intersections show how many diagonals meet at that point. The diagonal lines must never form a closed loop.
When a wall ends in one circled number, we write for convenience "The cell belongs to the number".
I call the first technique of this introduction fill-out. Consider the second sentence of the rules: the numbers. In two cases the cells around a number can directly be filled:
1. The number of cells that belong to a number is already equal to the number. In that case all other cells do not belong to this number. In the example below, this is the case for the numbers in the bottom row and the zero in the top right corner.
2. The number of cells that do not belong to a number is so high that all of the other cells belong to this number. This is the case forhe numbers in the middle row and the 1 and the 2 in the top row.
Next consider the third sentence of the rules: closed loops. In the following two cases it is easy to see that the given conclusions can be drawn.
Solution code: The marked column followed by the marked row. For each node write the number of diagonals that meet at that node (all together 2 times 11 numbers).

I don't understand how to enter the solution code. Can someone help?

And hidden comment means hidden from those, who haven't solved it yet. All solvers of the puzzle can read it and discuss the solution.

@Dean: You have the list of your solved puzzles on your User Pages here in the portal. And in each puzzle there is a link to a full list of solvers. So your achievement is logged :-).

Guess I'm more used to entering row first. Took a while to figure out I just swapped the two sets and I didn't actually solve the puzzle incorrectly.

cool. Endlich mal wieder was für die Anfängerserie. Hab's eingetragen.
