Sudoku-Pro

This is a variant of a very classic Sudoku game. You need to fill all the squares, ensuring that the icons in the same row, column and block are all different.

Gameplay:

Click on the blank square, then select an icon to fill it.

Check each row, each column, and each grid to see if there are any duplicate icons. Once all the cells are filled and the conditions are met, the challenge is successfully completed.
