Skyscraper puzzles are a common type of Latin square logic puzzles. I’m currently coding a Python program that will solve them, particularly ones of a large size, with minimal usage of guessing techniques. Here is a draft of a hopefully bug free solver. You can download the .txt file below along with directions for usage.

When you are ready to use the solver, change the file extension to .py and open the file with python. First you will be asked for the grid size. Up to size 9 is supported for now. Then you will be asked to input the border clues. Start in the top left corner and go clockwise, with empty clues as zeros. Lastly, enter any given node values. They are entered as three digit numbers, with the first digit being the row (the top row is 1), the second digit being the column (the left column is 1), and the third digit being the clue. Then you’re all done, and the solver can work its magic!
