Skyline Atelier · Towers
Build a skyline that matches every edge view: use each height once per row and column while taller towers hide shorter ones. Fifteen original-engine Towers puzzles across 4×4, 5×5 and 6×6 cities, with an interactive side-view preview, keypad and keyboard controls, conflicts, undo, hints and local saves.
