Color Sudoku

Colour Sudoku is a variation of the classic Sudoku game where, instead of numbers, different colours are used to fill the grid. The game is played on a 9×9 grid, divided into 3×3 sub-grids. Each row, column, and sub-grid must contain all the colours 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 colours so that each row, column, and sub-grid contains all the colours exactly once. Playing Colour Sudoku requires logical thinking and deduction skills, as you need to identify which colours can fit into the empty spaces based on the colours already placed in the grid. The game can be played at different levels of difficulty, with easy, medium, and hard puzzles available.
