Skyscrapers
Fill in tower heights 1–N with no repeats in a row or column; the edge clues say how many towers you see from that side, since tall ones hide short ones.
How to play — Skyscrapers
Every row and column holds the heights 1…N with no repeats — like Sudoku.
Each edge number tells how many towers are VISIBLE looking in from that side: taller towers hide all shorter ones behind them.
Tip: a clue “1” means the very first tower is the tallest (N). A clue “N” means heights climb 1,2,…,N in order. Tap a cell, then a number below — X clears.
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.
