After jumping on the U-Bahn train I wanted to draw attention to another puzzle genre that seems to be off the radar: Icelom. It struck me as a genre that has a lot of potential for hybrid puzzles, and I think this can be attributed to 2 main reasons. First, the dual nature of the path/loop combines naturally with any puzzle that involves two types of cells. Second, the concept of visiting numbers in ascending order can give a new meaning to standard clues. I chose Fillomino for this puzzle, but I think there's room for many other variations as well, I may try some other ideas in the future. For now I hope you'll enjoy this first glimpse of Icelom, it should be fairly approachable.

Rules

• Shade some cells in the grid. Divide the remaining unshaded cells into orthogonally connected regions, and enter a number into each unshaded cell equal to the size of its region. Shaded cells do not contain numbers.


• Draw a path through the centers of some cells, entering the grid at the “IN” marking and exiting at the “OUT” marking.


• Two perpendicular line segments may intersect each other only on shaded cells, but they may not turn at their intersection or otherwise overlap. The path may not turn on shaded cells.


• The path must visit all unshaded cells, but each region must be visited exactly once. The size of regions must strictly increase along the path.
