What is Swordfish sudoku?

Swordfish Sudoku is a variant of the popular logic puzzle game, Sudoku.

The difference is that Swordfish Sudoku uses two Sudoku grids placed side by side.

The grid on the left contains the numbers 1 to 9, while the grid on the right contains the letters A to F.

The numbers in each 9×9 grid must be placed one per column and one per row.

In addition, the numbers in each 3×3 grid must be placed one per diagonal.

The numbers in the Swordfish Sudoku grid can be placed in any order.

In short, we say that the swordfish is a special symbol that can be used to help solve the puzzle. It can be placed in any of the squares in the grid, and it will indicate the two numbers that are adjacent to it on the grid (either horizontally or vertically).

Sudoku swordfish pattern

The Sudoku Swordfish pattern is a sequence of moves that can be used to solve any Sudoku puzzle.

It’s a fairly simple pattern, and once you get the hang of it, you can solve any Sudoku puzzle in just a few steps.

The Sudoku Swordfish pattern is made up of six basic moves:

  • The two-by-two move
  • The one-by-one move
  • The swordfish move
  • The X-move
  • The Y-move
  • The Z-move.

The patterns are made up of six steps and can be used to solve any Sudoku puzzle.

  • The first step is to find the two corners of the swordfish.
  • The second step is to find the two Right squares of the swordfish.
  • The third step is to find the two Left squares of the swordfish.
  • The fourth step is to find the two middle squares of the swordfish.

Finned swordfish sudoku

A Finned Swordfish pattern contains a swordfish in every cell except one, i.e. three columns with candidates in every row except one, and vice versa.

This mechanism is based on the premise that if one of the Swordfish’s fins is false, the Swordfish as a whole is false.

Example

Here is an example that will help you better understand what we are saying.

Row 2: There is only one candidate 3. Column 7: Row 2. Only columns 2, 5, and 8 have the candidate’s name in them. Row 2: There is only one candidate 3. Column 7: Row 2. Only columns 2, 5, and 8 have the candidate’s name in them.

Column 7’s row 2 should not have 3.

A swordfish pattern is correct if Columns 2 & 5 are both empty, so can the threes in Columns 2 and 8 be taken out?

If column 7, row 2, has a 3, the upper-right box can’t have any 3s in it.

They may have to get rid of one or both of the three highlighted in green at some point.
