You may be able to get rid of this common number. However, Y-Wing can only be used if both pincers have precisely two numbers and one of the 2 numbers is the same across both pincers. The pincers seem to be the green squares inside the figure below. Pincers are a term used to describe the two coordinates of conjugate pairs. If any one of the two possibilities in the pivot makes a conjugate pair in 2 distinct units, you can apply Y-Wing. The pivot is indeed the red square as shown in the figure below. This square is also known as a pivot or a hinge. Starting with a square with exactly two candidates, Y-Wing moves on to the next step. 4 will go at B1 and D6 otherwise, 7 and 8 will be used up, and B6 will be empty.Ĭandidate 4 in D1 is the only one that can see the yellow particles and, therefore, should be eliminated. You really cannot ask for a more illustrative example. The next stage will be included since it demonstrates a nice rectangular alignment resembling the theoretical figure. The pairing in J2 is related to such pincer cells. The initial Y-Wing locates an AB cell and A2 that connects 8 to the B3 pair and 3 at J2.Ĥ is shared with both pincer cells and must be placed whether in B3 or J2 so that 4 in H3 could be deleted.īecause of the placement in column 1, the next Y-Wing gets two candidates.Ĩs at B1 and C1 may see the 8s in A2 and G1, which are likewise in B1 and C1. The first three are shown below, but the remaining examples can be found by loading the riddle into the solver. Five Y-Wings DemonstrationĪnother excellent ‘difficult’ Sudoku puzzle, this time with a chain of five Y-Wings, demonstrates the entire extent of this method. Since they share the very same box in Figure 3, BC can see AB.īecause they are on the same row, AC can see AB.Īll cells are designated with a red C which this Y-Wing can delete whenever number C is visible to BC and AC. Our A, B, and C can see a lot more cells if they are more tightly aligned than merely the corners of both the rectangle they form. In this situation, two overlapping cells are ‘seen’ by both. This illustration of a puzzle shows the area of influence that two example cells, designated red and blue, have.Īll the erythrocytes are visible to X, while all the blue cells are visible to Z. There is no way a C can exist there, and this can be eliminated. If AB is revealed to be B, C will make it into the top right-hand corner.Īnything happens, C is assumed to be in one of the two C cells.īoth Cs can see the red C since the unit converges BC and AC. If the answer to that cell is A, then C will undoubtedly appear in the bottom left-hand corner.
There are two possibilities in each of the three corners: AC, AB, and BC.
