1.Look for singletons: As with level 1, scan each row, column, and 3x3 box to look for any cells that have only one possible number. Fill in these cells.
2.Check for pairs: Look for pairs of cells in a row, column, or 3x3 box that have the same two possible numbers. If you find a pair like this, eliminate those two numbers from the other cells in the same row, column, or 3x3 box.
3.Look for triples: Similar to pairs, look for three cells in a row, column, or 3x3 box that have the same three possible numbers. Eliminate those three numbers from the other cells in the same row, column, or 3x3 box.
4.Use process of elimination: If you have a row, column, or 3x3 box that has all but one of the numbers filled in, then use process of elimination to figure out what the remaining number must be.
5.Keep track of possibilities: In some cases, there may be multiple possible numbers for a cell. Use pencil marks to keep track of all the possible numbers for a particular cell.
6.Repeat steps 1-5: Keep scanning the puzzle for singletons, pairs, and triples, and use process of elimination to fill in the remaining cells.
Here's an example of how to solve a level 3 Sudoku puzzle:
1.Start by scanning the first row. You'll notice that there's only one possible number for the first cell, so fill in a 3.
2.Scan the second row. You'll notice that the fourth cell has only one possible number, so fill in a 6.
3.Now scan the second column. You'll see that the second cell has only one possible number, so fill in a 7.
4.Scan the third row. You'll notice that the sixth cell has only one possible number, so fill in a 4.
5.Keep repeating these steps, scanning rows and columns for singletons, pairs, and triples, and using process of elimination to fill in the remaining cells.
6.Eventually, you'll have filled in all the cells and solved the puzzle!
Remember, level 3 Sudoku puzzles are a bit more challenging than level 1, but still relatively easy. Keep practicing and you'll be able to solve more difficult puzzles in no time!
