The Sudoku X-Wing strategy is one of the most recurrent techniques that can be applied to Sudoku puzzles from a medium difficulty level onwards. It is a very straightforward technique with an easily identifiable pattern. It focuses on one single digit and its goal is to restrict the number of cells that can have that number as a possible candidate. Together with the Swordfish , the Sudoku-X-Wing technique is also a valuable strategy for any player to learn as it branches out into more complex patterns and techniques that are required to solve impossible puzzles. To be able to apply this technique, the player must find 2 rows or 2 columns where a single digit is a candidate in only two cells of each. These cells must be aligned by column and row, forming a square or rectangle when connected. The basic principle of this technique is simple.

With just two Zs in the pincer cells we get more cells elsewhere which could potentially contain a Z to eliminate. The overlap is greater with less cells to line up. Same with F1. If any of the three are 1 then 1 is still part of the formation. Any 1 visible to all three cells must be removed, in this case in F7. The hinge cell is on E8 and the common candidate is 6. The 6 in E9 can see all the 6s in the whole XYZ formation. They also require one Naked Pair.

It starts with either two parallel rows or two parallel columns. I'm keeping the the name turbot crane when a strong link exists in box. Some do, some teach, the rest look it up, sudoku xyz wing.

X-Wings are fairly easy to spot, but a little harder to understand than some other techniques. Like others it relies on using positions of pencilmarks to infer enough to allow you to eliminate some other candidates. Once you've satisfied yourself that there aren't any easy methods you can apply to move forward, take a look at the candidate positions for 6, in rows 4 and 9. The trick to understanding X-Wings is to imagine what would happen if you chose just one of those positions - what would it do to the others? Imagine making the top left of those cells be the 6 - it would force the other candidate out on its row, and also force the candidate in the bottom left out too the red arrows.

WXYZ Wings. The first cell in a WXYZ-Wing has three or four candidates while the other three, called the wings, have two each. Each of the wings must share one candidate with the first cell, that's part of sharing a unit but each wing must share a different value. If the second candidates in the wings are all the same, and are also the same as the left-over candidate of the first cell if the first cell has four candidates, then if any fifth cell shares that candidate and a unit with all the others, that candidate can be eliminated. Consider the example on this page. The highlighted cell with 5, 8 and 9 as candidates is the first cell, and the other three are the wings. One wing shares the 5 with the first cell, another shares the 8 and the last shares the 9.

Tip The trick to spotting X-Wings is to look for the rectangles of possible candidates. In WXYZ-Wing you explain it quite succinctly by saying "The easy principle is that each possible value of the hinge cell results in a Z value in one of the cells in the [WXYZ]-Wing pattern, thus leaving no room for a Z on any cell all [four] can 'see'. SpAce wrote: I would also love to replace "Empty Rectangle" with "Grouped Turbot Crane" to be similar to its grouped siblings, but obviously that's never going to happen. They make good practice puzzles. Play now! In this example, the 3 circled in red become impossible when both sets are applied, except for the one in row 2, column 7, which is the solution for that group. In the example above, it is clear that the number 8 has only two possible solutions within the highlighted columns. Imagine making the top left of those cells be the 6 - it would force the other candidate out on its row, and also force the candidate in the bottom left out too the red arrows.
