Here's an unusual genre Tyrgannus came up with, and my own spin on it! Draw a loop which travels through the centers of some cells. The loop may move only between orthogonally adjacent cells, unless one of the cells is icy, in which case it may move diagonally. The loop may not travel through black cells, and must travel through all icy cells. Two line segments may intersect each other only on icy cells, but they may not turn at their intersection or otherwise overlap. The loop may not turn on icy cells Solve on Penpa+ https://tinyurl.com/yc8jr3xp
