![]() That means each row, column, and 3×3 square in a Sudoku puzzle must contain ONLY one 1, one 2, one 3, one 4, one 5, one 6, one 7, one 8. No row, column, or 3×3 box can feature the same number twice. So all conditions are met - 3 rows, 3 columns. In Sudoku, you must complete the grid so each row, column, and 3-by-3 box (in bold borders) contains every digit 1 through 9. The cells containing the six entries are lined up exactly in 3 columns (1, 2, and 9 - for clarity, they are also highlighted with a white and orange border). These cells (called pincers) should be in the. Then, we'll look for two more cells with 2 notes as well. To start, we need to find a cell with exactly two notes. Let's take a look at this technique with an example. There are only 2 occurrences of the six in each of these rows. 'Y-Wing' technique is similar to 'X-Wing', but it based on three corners instead of four. ![]() In the example, the "fish digit" is a 6, and the lines 1, 6, and 9 are the "base" (highlighted by the green guide lines). First, we need to find the so-called "fish digit" and the "base". Most of the techniques used to solve Sudoku puzzles work by eliminating candidates until there is only a single candidate left for a particular cell, a naked. The numbers shown in the example are the givens. Each region, row, and column contains nine cells each. Traditional Sudoku is a 9×9 puzzle grid made up of nine 3×3 regions. Let's look at an example of using the Swordfish technique. You could play Sudoku using any nine symbols or colors. That is, to use the technique, you must go to a certain level of abstraction and find three rows or three columns that each have two occurrences of candidate numbers. In mechanics, "Swordfish" is similar to "X-Wing", but uses 3 columns and 3 rows instead of two. The technique helps to exclude hypothetically suitable candidate numbers and to reduce the scatter in the selection.
