Sudoku: Color

Sudoku — but make it colorful.

Sudoku: Color replaces numbers with 9 vibrant hues, making every puzzle a visual delight that's easy to pick up and impossible to put down.

HOW IT WORKS
Fill every row, column, and 3×3 box with all 9 colors — no repeats. The same satisfying logic as classic Sudoku, but the color format welcomes newcomers while keeping all the depth veterans love.

FOUR WAYS TO PLAY
