Sudoku with Squares
Online Sudoku with Colored Squares – Game Rules
The goal of the game is to fill the entire 9×9 grid with squares in 9 different colors so that:
in every row, each color appears exactly once,
in every column, each color appears exactly once,
in every 3×3 block marked with a bold border, each color appears exactly once.
At the start of the puzzle, some squares are already filled with colors. These are fixed cells and cannot be changed.
👉 Click on a cell to select it, and then choose the color of the square from the panel below.
If the chosen color is incorrect, the cell will be highlighted in red.
You can also use the Hint button to get the correct color for the selected cell.
At any moment, you can check the correctness of the entire board or ask for an automatic solution.
🎨 Extra features:
After you select a color, all squares of that color briefly rotate, which makes it easier to spot patterns quickly.
A correctly placed square explodes with a fun effect and reappears neatly in the chosen cell.
