I found this puzzletype here: https://www.janko.at/Raetsel/Linesweeper/index.htm
This is one I set myself:
Rules:
Draw a single closed loop in the grid (that doesn't branch or cross itself). A number in a cell indicates how many of the 8 adjacent cells are visited by the loop. The sections of the loop run horizontally and vertically between the centers of horizontally and vertically adjacent cells. The loop never visites a cell with a number in it.
Solution code: row 2, row 8 (1 for straight loop, L for bent loop, 0 for no loop)

Humblebrag. I'm the inventor of this puzzle type.
