Color Sudoku is a variation of the classic Sudoku game where instead of numbers, different colors are used to fill the grid. The game is played on a 9x9 grid, divided into 3x3 sub-grids. Each row, column, and sub-grid must contain all the colors exactly once. The objective of the game is the same as the traditional Sudoku game, which is to fill in the empty spaces in the grid with the nine different colors so that each row, column, and sub-grid contains all the colors exactly once. Playing Color Sudoku requires logical thinking and deduction skills, as you need to identify which colors can fit into the empty spaces based on the colors already placed in the grid. The game can be played at different levels of difficulty, with easy, medium, and hard puzzles available. Color Sudoku is a fun and challenging game that can be played alone or with friends. It is a great way to exercise your brain and improve your problem-solving skills while enjoying a colorful and visually appealing game.
