About Colour Sudoku
Classic sudoku rules meet vibrant colours. Instead of numbers 1-9, you're placing nine different colours. Same logic, totally different vibe - perfect if you're more visual than numerical. Play unlimited puzzles at your own pace.
How to Play
Each row, column, and 3x3 box must contain all nine colours exactly once. Use the colour palette to fill in empty cells. The logic is identical to classic sudoku, just with colours instead of digits. No maths required!
Colour Sudoku Tips
Casual mode is unlimited practice. Use it to sharpen pattern recognition, experiment with strategies, and learn how colours interact across rows and columns.
If you feel stuck, try solving a single colour across the whole grid. A fixed colour order makes scanning faster and reduces hesitation.
