Fun With Sudoku

Game Rules:
Sudoku is a classic puzzle game. Fill the grid so that every row, every column, and every 3x3 block contains the numbers 1 to 9, with no repeats in each row, column, or block.

How to Play:
Click on any empty cell to bring up number options. Select a number to fill in the space. If you click a cell you have already filled, you can change the number by selecting a new one.

Memo Function:
If you're not sure about a cell, you can use the handwriting feature to make a memo or jot down possible numbers.

Difficulty Levels:
There are three modes to choose from: Easy, Normal, and Hard.

Hints:
If you get stuck, a hint will appear after a certain amount of time to help you continue.
