Sudoku Level 8 ( Medium : 29 clues )
00:08:581.Look for singletons: As with easier puzzles, 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 and triples: Similar to easier puzzles, look for pairs and triples of cells in a row, column, or 3x3 box that have the same two or three possible numbers. Eliminate those numbers from the other cells in the same row, column, or 3x3 box.
3.Use advanced techniques: Level 8 puzzles often require more advanced techniques, such as X-wing and swordfish, which involve finding patterns in the possible numbers for cells in different rows and columns. These techniques are too complex to explain in detail here, but there are many online resources that can help you learn them.
4.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.
5.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.
6.Repeat steps 1-5: Keep scanning the puzzle for singletons, pairs, and triples, and use process of elimination and advanced techniques to fill in the remaining cells.
Here's an example of how to solve a level 8 Sudoku puzzle:
1.Start by scanning the first row. You'll notice that the first cell has only one possible number, so fill in a 5.
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 third cell has only one possible number, so fill in a 2.
4.Scan the fourth row. You'll notice that the sixth cell has only one possible number, so fill in a 3.
5.Keep repeating these steps, scanning rows and columns for singletons, pairs, and triples, and using process of elimination and advanced techniques to fill in the remaining cells.
6.Eventually, you'll have filled in all the cells and solved the puzzle! Remember, level 8 Sudoku puzzles require more advanced logic than easier puzzles, but they are still manageable with practice. Keep at it and you'll be able to solve more difficult puzzles in no time!
