Advanced Solving Sudoku Technique XYWing

XY Wing is sometimes just called "Y Wing". If you ask me, "V Wing" is more appropriate! In order for this to work, the cell in the middle of the "Y" (green) must intersect both of the cells on its wings (blue), while the two wing cells may not intersect each other. The XY wing technique is a technique that is often compared to the hooks of an eagle and its prey. The objective is to find the hook cells and proceed to eliminate the prey. The XY wing technique First, we start by finding a column with a cell having only two candidates, called pivot. The candidates in the cell are called X and Y.

How To Use The XYWing Pattern To Solve Sudoku

A Sudoku XY-Wing pattern occurs in many of the more difficult Sudoku puzzles. XY Wing involves 3 different cells — each with exactly two candidates — that are related to each other in such a way that you can make some logical conclusions. XY Wing (sometimes called Y Wing) is another advanced technique for eliminating candidates. It starts by finding a cell with only two candidates (a bi-value cell) called the pivot. These 2 candidates are called X and Y. In our sample - R5C5 is the pivot, X=6 and Y=9. XY Wing also known as Y Wing is an advanced Sudoku tutorial. XYZ-Wing example 1 : Load Example or : From the Start In this example the candidate number is 1 and F9 is the Hinge. It can see a 1/2 in D9 and a 1/4 in F1. We can reason this way: If D9 contains a 2 then F1 and F9 become a naked pair of 1/4 - and the naked pair rule applies. Same with F1. The XY-Wing technique uses three cells and three candidates marked X, Y and Z to analyze the chain. One cell (pivot) has exactly two candidates X and Y, the other cell (pincer 1) that "sees" the pivot, has exactly two candidates Y and Z, the third cell (pincer 2), which also "sees" the pivot, has exactly two candidates X and Z.

An XY-Wing is a group of three cells, one sharing a unit with the other two, each having only 2 candidates. The two cells that share a unit with the first are called the Wings. Each of the wings must share one candidate with the first cell, (that's part of sharing a unit) but of different values. XY-Wing - Sudoku Solving Technique Sudoku Solving Techniques Consider the following partial Sudoku puzzle: XY XZ YZ The pink cell and the two yellow cells form a XY-Wing pattern. Notice that each of these three cells has two candidate digits. The pink cell has digits X and Y as candidates. XY-Wing Consider the following partial Sudoku puzzle: The red, green and yellow cells form a XY-Wing pattern. If the red cell is X, then the yellow cell must be Z and therefore the blue cell cannot be Z. If the red cell is Y, then the green cell must be Z and again the blue cell cannot be Z. So in either case, the blue cell cannot be Z.

Three empty squares are constrained in such a way that we can infer that some empty squares surely cannot be one certain number. XY Wing The XY Wing strategy uses three cells that contain two and only two candidates and have common values in the cells. Even though the name is similar, the XY Wing strategy is not related to the X Wing strategy. The Pattern. Find a cell that has only two candidates. Call this the XY cell. Y-wing - Sudoku technique "Y-wing" technique. "Y-Wing" technique is similar to "X-Wing", but it based on three corners instead of four. Let's take a look at this technique with an example. To start, we need to find a cell with exactly two notes. We'll call this cell a pivot. Then, we'll look for two more cells with 2 notes as well.

An XY-Wing is a solving technique that uses a short chain of 3 cells. The cell in the center is called the pivot. The other 2 cells are the pincers. The chain uses only 3 digits, symbolically named X, Y and Z. Any 3 digits can replace these letters. The pivot contains candidates XY, which explains the name of this technique. #sudokuguy #sudoku http://www.sudokuguy.comPart 2 will be included in the next tutorial #44This is another advanced technique which i.
