Color Sudoku, also known as Suirodoku, revolutionizes traditional sudoku by combining numbers and colors in each cell. While regular sudoku uses only numbers, color sudoku requires placing both a number (1-9) and a color in every cell.
This creates 81 completely unique number-color pairs across the entire 9×9 grid, adding a fourth constraint to the classic sudoku rules and opening up entirely new solving strategies.
Whether you know it as "color sudoku," "colour sudoku," or "sudoku with colors," Suirodoku represents the ultimate evolution of the beloved puzzle game.
