Solve the naked single and the logjam is broken. When you remove the 4s, you now expose a naked single in (R7, C7). The cells circled in red may have the number 4 removed from them safely. Therefore, it is safe to eliminate the 4s from column 3 and column 7 except for the highlighted positions. We do know that it must reside in two of the four positions highlighted. At this point, we do not know which pair the 4 will reside in. Sudoku rules forbid any other combination. This means the 4 will reside in the pair (R2,C3) and (R5,C7) or in the pair (R2,C7) and (R5,C3). The two positions have to be diagonally opposites forming an X (hence the name). ![]() The number 4 can only appear in two of the four positions. These four positions are highlighted in grey. In row 5, the cells are (R5, C3) and (R5, C7). In row 2, the cells are (R2, C3) and (R2, C7). Each row has the number 4 in only two cells. In the example shown, an X Wing pattern occurs in row 2 and row 5. This candidate must reside in both rows and share the same two columns or vice versa.

You will need to partially solve the puzzle to reach the picture shown.
