Unfortunately, applying it requires very high levels of concentration and the outcome can be uncertain. Forcing Chainsįorcing chains is one of the easiest advanced Sudoku strategies to understand. It can then be safely removed from that cell, leaving only numbers 1 and 2 as candidates to it. When testing them on the grid, the player finds that the 4 highlighted in red would be an impossible candidate in both cases. Thus, there are only two sets of possibilities within this chain for number 4, the green and the yellow sets. In this grid, number 4 is a candidate to two cells in three different rows, allowing the player to use the Swordfish technique.Ĭonnecting them reveals that whenever a digit highlighted in green is possible, the yellows become impossible and vice-versa. The player can then put them to the test and eliminate that number as a candidate to the cells where it would become impossible in both cases. These cells must also be united by column, regardless of the shape they create.Ĭonnecting them will result in a closed chain that reveals two sets of possible placements for that digit. To apply it, the player must find a digit candidate to two cells in the same row, in three different rows. This strategy helps to eliminate a candidate from cells too. ![]() It can then be eliminated as a candidate to that cell. Testing the pairs on the grid shows that the 5 highlighted in red would be impossible in both cases. By connecting the cells containing it, it is easy to see that in this situation only the pairs in green or yellow could be possible. In this example, the number 5 forms the necessary pattern to apply the X-Wing strategy. The next step will be to test those sets on the grid and eliminate the digit from any cell that would become impossible in both situations. By making an X linking diagonally the two opposite extremities of this rectangle, the player finds only two possible sets of positions for that digit. The player can use this strategy when there is one candidate repeated in four cells that form a square or rectangle when mentally connected by row and column. ![]() It can also be applied in some intermediate levels, although its incidence is very low in these cases. The X-Wing method is one of the most basic advanced Sudoku strategies. Regardless, their application always demands high levels of concentration from the player as they work by deduction.
