Skyscrapers

The goal is to place a skyscraper on each space of the NxN grid. The height of the skyscraper must be from 1 to N.

Much like sudoku, each row and each column must contain only one skyscraper of any given height.

The numbers on the outside of grid represent the number of skyscrapers someone could see standing there.
Taller skyscrapers hide shorter ones.

Four levels of difficulty with grids ranging from 3×3 up to 8×8. Most grid sizes and difficulty contain 500 puzzles for a total of almost 10 000 puzzles.

Smaller grids are great for younger players or if you just want a quick game. Larger grids will provide a challenge to even the best puzzle solvers.
