The Sudoku Swordfish strategy is a single-candidate technique that uses 3 rows and 3 columns. This means the player only needs to focus on one digit. The grid must contain 3 rows or 3 columns where the digit is a candidate for only 2 or 3 cells. Each cell must be connected to another by row/column, regardless of the shape created when they are link...
This is the basic configuration needed to be able to apply the Sudoku Swordfish strategy to rows. In the 3 highlighted rows, the digit is only a candidate for three positions. Each position is connected to another by column. The solution for the digit in each of the highlighted rows ensures that it cannot be present in any other position within the...
The column pattern follows the exact same principles as the row pattern, but inverted. The digit must be a candidate for only two or three cells in three different columns. Each cell must be connected to at least another by row. By applying the Sudoku Swordfish strategy, the player can thus eliminate that digit as a candidate for any other cells wi...
In this variant, the player finds the digit is a candidate for an extra cell in one of the rows or columns. For example, if the player is looking for a configuration of 2/2/2, it means the digit is a candidate for 3 cells in one of those columns/rows. If the pattern is 3/3/3, then one row/column will have 4 cells with the digit. To apply this strat...
The Sashimi Swordfish requires the presence of fins on the grid. This strategy can only be applied to sets of 2 digits per row or column. Contrary to the Finned technique, the player is now one cell short of finding the pattern to apply the Sudoku Swordfish strategy. Only candidates within the odd-out cell can be eliminated with this technique. It ...
The "Swordfish" technique is an advanced Sudoku strategy. It's usually applied in the hard levels of Sudoku puzzles to eliminate candidates. "Swordfish" is similar to X-wing but uses three sets of cells instead of two. To understand better, let's take a look at the example.
The "Swordfish" technique is a great way to solve those tricky Sudoku puzzles with lots of empty cells. The technique helps us rule out numbers that might be a good fit and makes the selection process more streamlined.
Sudoku Swordfish Technique with Examples. Before diving into the Swordfish technique, make sure you fully understand the X Wing Technique as the Swordfish builds on that. The idea behind X Wing extends easily: Consider any one candidate. Consider any N distinct rows, N>0.
The Swordfish strategy is an advanced technique in Sudoku puzzle solving that can help you make deductions and narrow down possibilities. It is similar to the X-Wing strategy but expands the concept to three rows or three columns.
A Swordfish is a 3 by 3 nine-cell pattern where a candidate is found on three different rows (or three columns) and they line up in the opposite direction. Eventually we will fix three candidates somewhere in those cells which excludes all other candidates in those units.
