(a small spoiler)

Checked: exactly one solution, reachable by logic. The level is the hardest technique our solver needed, not the grid size.

Rule breaks (a repeated height) always show in red. "Show mistakes" also marks cells that disagree with the solution.

Why the small grid is not the easy one

Skyscrapers difficulty comes from how much a clue leaves open, not from the number of cells. A 4x4 with few clues can be harder than a 6x6 with clues all round, which is why the level and the size are chosen separately.
