Skyscrapers consists of a square grid. The goal is to fill in each cell with numbers from 1 to N, where N is the size of the puzzle's side. No number may appear twice in any row or column. The numbers along the edge of the puzzle indicate the number of buildings which you would see from that direction if there was a series of skyscrapers with heights equal to the entries in that row or column.

Basic Rules

• Fill each cell of the grid with numbers from 1 to N.
• No number may appear more than once in any row or column.
• The numbers on the edges of the grid indicate how many skyscrapers are visible from that direction.

Additional Rules for Skyscrapers

• A skyscraper blocks the view of any shorter skyscrapers behind it. Only taller skyscrapers or those of increasing height can be seen.

Basic Solving Tips

• Start with the edges: Use the numbers on the edges to determine which buildings might be visible.
• Look for obvious placements: For example, if the edge number is 1, the tallest building must be placed in the first visible position.
• Use process of elimination: Determine where numbers can and cannot be placed based on the rules.
• Check rows and columns: Ensure each row and column contains all numbers from 1 to N without repetition.
