Root Sudoku is a fresh and innovative puzzle game that blends classic Sudoku rules with the logic of perfect squares. In addition to the standard rule — no duplicate numbers in any row, column, or 3×3 block — three unique "√ rules" bring an extra layer of depth: Red frames: When the digits are joined together, they must form a perfect square Blue frames: The sum of the digits must be a perfect square Green frames: The product of the digits must be a perfect square These special rules challenge your logical thinking like never before. Each puzzle features its own intricate combination of frames, requiring a mix of calculation and deduction. If you're tired of ordinary Sudoku, Root Sudoku is the brain game for you. With built-in error checking and a smart calculator tool, solving has never been smoother. Can you unravel every rule and conquer the grid?
