Rule:
Draw a loop through the centers of some cells. Two perpendicular line segments may intersect each other, but not turn at their intersection or otherwise overlap.
Clues represent the length of loop segments each time it enters the entire 3x3 area the clue cell is in the middle of.
The grid is toroidal, which means that first and last row/column are considered adjacent. This means that lines going up from the top row should match the lines going down from the bottom row; lines going left from the leftmost column should match the lines going right from the rightmost column.
Clue format: When all numbers in the clue are one-digit, comma is omitted. Otherwise comma is not omitted.
