Hi all!
Does someone know the puzzle below?

You have a blank grid filler with some numbers, then you have to "throw rays" starting from the filled cells. From each cell with a number you count how many cells you cover starting from that cell, that number should be equal to the number in the cell.

Does someone know where can I find more of that puzzle, and what are the advanced logic steps to solve that. I have only solved easy puzzles of that type.

I didn't know it, altough it reminded me of Light Up, which is different.

Never having done it myself, I wouldn't know any manual techniques either, but as a programming problem it can easily be converted to a exact matrix cover problem, and solved using DLX.
