Welcome to a puzzle that adds a simple mathematical restriction to your solving! This Square Numbers Sudoku is my 35th contribution to the Fun With Sudoku Series and was originally created for the 21st Indian Sudoku Mock Test. It’s a very old puzzle that remained unpublished in my notebook for years, and I'm glad to finally share it. The rule is straightforward: greyed cells within the grid can only contain square numbers—specifically 1, 4, or 9 (the squares of 1, 2, and 3). This simple constraint adds a focused layer of logic, making it a great puzzle for a relaxed solving session. It's print-friendly and perfect for those who enjoy a subtle mathematical twist.
Rules of the Square Numbers Sudoku
Classic Sudoku Rules apply. Additionally, greyed squares can only contain square numbers, i.e., the number that we can get after squaring a number. In other words, greyed cells can contain only 1, or 4,9 numbers.
