This Sudoku puzzle has 4 main areas.

4 columns

4 rows

4 colors

4 2x2 blocks

Add BLUE to the other 2x2 areas using the paint bucket.

Make sure you don’t have any blues in the same rows or columns.

Next color will be yellow.

Because yellow is already in this block, you will be able to put it in all the remaining 2x2 blocks.

Next is orange. You do not have to do all of one color.

To make sure you are doing things right, you can place one orange, then move onto another color and come back to orange later.

Then finish it up by adding the remaining orange.

Make sure you don’t have the same colors in any row or column.
