数独-颜色

This is a variant of a very classic Sudoku game. Within a 9X9 grid, 9 different icons are placed, ensuring that each row, each column, and each section contains 9 different icons. It is extremely challenging.

Gameplay:

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

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