Thus, if all the digits but one appear in a row, the missing digit must appear in the empty cell. Rule of 45 Each sudoku region i.
Thus, each sudoku region has a total value of If S is the sum of all the cages contained entirely in a region, then the cells not covered must sum to S.
Eigentlich auch ganz einfach, doch viele haben es noch nie probiert. Zählen Sie ein einzelnes Kästchen durch auf der Suche nach einer Zahl.
Alle berührten Zahlen dürfen nicht in dieses Feld. Berührt werden: 1, 2, 3, 4, 5, 6, 7 und 8. Was bleibt anderes übrig, als bei M3 die 9 einzutragen?
Eine 8 ist gesucht! Oben links fehlt noch die 8 und im rechten mittleren 3x3-Feld sind auch nur noch zwei Kästchen dafür übrig. In den entsprechenden Zeilen und Spalten kann die 8 dann also nirgendwo sonst als in diesen jeweils beiden Feldern stehen.
Wenn wir nun in den 3x3-Block rechts oben schauen, ergibt sich daraus nur eine einzige mögliche Stelle, wo die gesuchte Zahl noch hin kann — Sie haben eine 8 gefunden M4.
Now this square is solved, you can complete the Sudoku using easy methods. In general, an x-wing is found when for two rows, there are two, and only two, possible squares in which a particular number can be placed, and for both rows these squares lie in the same two columns.
In this case, this particular number can be eliminated as a possibility for all other squares in those two columns. Of course, you can exchange rows and columns in this definition.
From today onwards, you will find the swordfish technique become a regular feature in the Times2. The swordfish is similar to the x-wing technique, but on a larger scale, with three rows and columns instead of two.
If lines are drawn along the rows and columns, connecting the squares involved, they can form two rectangles, connected at the corners.
One more scan reveals the cell. In this case, the digit you wish to place may not actually appear in a certain row or column - and yet, because you know which row or column it will occupy, you can eliminate that region from consideration in the block where you are working.
This also is demonstrated in the videos. Sometimes you will encounter a situation that points to a specific row or column for a given digit, because of where that digit must be entered in the adjacent blocks.
For example, let's say that in Block 1 you have discovered that the 3 cannot be placed in the top row; and in Block 3, you notice the same thing—the 3 cannot be placed in the top row.
That tells you that the 3 must go in the top row in Block 2. You may even be fortunate enough to determine exactly which cell will take the 3.
The same technique can be used with columns, rather than rows. The picture here shows how we came to place the "1" digit in cell A technique that you may have learned with easier sudoku puzzles is One Choice or "What Fits?
If you wish to go looking for a cell where that technique might be used, remember that it is not the total number of digits appearing that matters—it is the number of different digits that counts.
So, rather than looking for a cell in a block with 4 digits, in a row with 6 digits, and in a column with 5 digits all of which may use the same digits , you may have better luck checking out a cell at the intersection of a row with 3 digits, a column with 3 other digits, and in a block that has 2 still unused digits, as long as those digits are different from one another.
Twinning or triplets or quads is another technique that is used often in the next levels of sudoku.
This concept works in two ways. One is known as a "naked pair. For example, 1 and 9. Since there are two cells and only two digits the same two , then one of the digits must belong to one of the cells and the other digit must belong to the other cell.
But even before you determine which cell takes the 1 and which one takes the 9, you already know that the 1 and 9 cannot go anywhere else in that region.
So if these twin cells are in the same block, then the 1 and the 9 cannot go in any other cell within that block.
If the twin cells are in the same row, then the 1 and 9 cannot go in any other cell within that row; the same is true if the twin cells are in the same column.
If you have penciled in any candidates, then you can use this principle of twinning to eliminate the twin digits from other cells in the same region , if they have shown up elsewhere.
Or you can avoid placing them in there in the first place, as you notice in the picture here. In that case, placing the candidates in Block 9 shows that only the 5 and 9 can be used in the empty cells.
Since they are both in the same row, then neither 5 nor 9 can appear as a candidate in any other cell within that row. If you first filled in the candidates for Row 8 of Block 8, you could include the 9 in cells 84 and 86 - initially.
But then, upon completing Block 9 or completing Row 9 of Block 8, you would see a Twin Pair a Naked Pair containing a 9; that tells you that the 9 could not be used either in cell 84 or Cookies are small pieces of text sent to your web browser that assist us in providing our Services according to the purposes described.
