Sudoku 4 is a great option for beginners or for those looking for a quick brain-teasing challenge. **

To solve Sudoku, you need to fill in the grid so that each row, each column, and each of the nine 3x3 subgrids contain all of the numbers from 1 to 9. Start by looking for numbers that are already provided in the puzzle and then use logic to fill in the remaining empty squares. Look for rows, columns, or subgrids that are missing a particular number and use the process of elimination to determine where each number should go. With practice and patience, you can gradually fill in all the squares to complete the puzzle. **
