Play Towers on brainstretch.
Build a skyline where each edge clue counts the towers visible from that side, with no repeated height in a row or column.
Edge clues show how many towers are visible from that side; taller towers hide smaller towers behind them. Each row and column holds every height once. A board may start with a few heights in place, marked with a pin; those can't be changed.
Select a cell, then enter a height. Notes switches the pad to pencil marks, for the heights a cell could still take.
