Latin square · visibility clues

🏙️ Skyscrapers

Fill the grid with tower heights 1–N so no height repeats in any row or column; edge clues tell how many towers are visible from that side (taller towers hide shorter ones). Puzzles are generated with a unique solution, in three sizes.

Time 0:00

Tap a cell then a number (or type 1–6, X/0 clears). Duplicates and broken clues turn red; satisfied clues dim. Example: clue “1” means the nearest tower is the tallest; clue “N” means heights ascend all the way.
