Snail Skyscrapers Puzzle – Unique Logic Challenge

Snail Skyscrapers is an original puzzle variation that I created for the Contest for Best Logic Innovation. This puzzle combines the classic Skyscrapers puzzle with an interesting spiral placement constraint. In addition to determining the building heights using visibility clues, you must also ensure that the digits follow a specific snail-shaped sequence from the outer edge toward the center of the grid. The combination of Skyscrapers logic and spiral ordering creates a fresh and enjoyable solving experience for puzzle enthusiasts.

Snail Skyscrapers Instructions

Fill the grid with digits 1 to 3 so that each digit appears exactly once in every row and column. Digits should be placed in order along the spiral path, starting from the entrance and continuing toward the center, beginning with 1 and ending with 3.

The cells represent buildings, and the digit in a cell indicates the building's height. Numbers outside the grid indicate how many buildings are visible from that direction. A building is visible if there is no taller building between it and the observer.
