In Sudoku, the player has to fill in the boxes in a 9x9 grid with the numbers 1 to 9 in such a way that each number appears exactly once in each row, column, and 3x3 block. Some of the numbers may already be filled in. You have to fill in the remaining numbers in the empty boxes.
Click on the box where you want to fill in the number and write the number. Use the numbers on the keyboard to write the numbers or click on the number buttons on the screen.
After filling in all the boxes, the program will check the numbers you have filled in and tell you whether they are correct or incorrect. After correcting all the incorrect numbers, the program will check them again and tell you whether they are correct or incorrect. You can make corrections until all the boxes are correct.
In Japanese, Sudoku means "single number"
This game tests your logic. It is a great way to have fun.
