Rule of Necessity This rule can be applied to sudoku regions i. In the former case, each region must contain all the digits one to nine. 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 It is possible to use some of the same techniques in Forced Choice as in actual solving of a puzzle.
That is, sometimes one choice will eliminate candidates in such a way that a specific digit appears in only one cell in a given row or column; in that case, that is the Choice that was forced.
Sometimes twinning may result in such a way that some digits can be eliminated within a block. While using Forced Choice, all of the choices are hypotheses, and they must derive from some previous action in the chain.
Once you encounter a contradiction, you know that the original choice you made was incorrect - if you have derived all of your choices through sudoku logic; and so the other candidate in the original pair must be correct and can be entered as an actual digit as shown in the Expert Sudoku Example video.
It can be very enjoyable to have a whole string of correct entries come from one contradiction. In some cases, it may be necessary to start the Forced Choice over once again, after completing just a few entries.
Good solvers have suggested all kinds of practical tips that have helped them. Some say to use only pen; some say to use only pencil; one commenter suggested using pen for the obvious, definite entries in the puzzle, then using pencil when you get to the entries that you feel less certain about.
Some like to go in numerical order to check and solve for digits; after finding all the definites possible in one round, they then go back through the digits in order again.
But some solvers prefer to start with the digits that appear most frequently among the givens; solve those as far as possible, then go back and pick up the ones that did not appear as frequently.
It is a good idea to count often; as you go through a row, column, or block, check to see where each digit will go or could go, and count off the digits as you check for them.
My own method is to start with what is obvious - those digits that appear the most often. I start by using Slice 'n' Dice as much as I possibly can with all of the obvious digits, then with the ones that are less apparent.
Then I turn to these other methods: "What Fits? I return to Slice'n'Dice frequently, perhaps immediately after I have placed a few digits by any other method, simply because it is so easy to use.
When I play Sudoku on Google-Plus, I have one more helpful little trick that works for me, although it may not for others.
That is, since this is on a computer, I keep a blank sudoku grid in a file on my desktop. When I have solved all of the obvious entries possible in the Google-Plus Sudoku Game itself, I open my blank grid and fill in candidates in each empty cell.
That makes it possible to see examples of "What Fits? I always fill in candidates in the region that has the fewest empty cells.
For example, if I see that a certain row has only two empty cells, then I fill in the two candidates in those cells in my grid ; in some cases, the fewest empty cells may be in the block or in the column.
On my computer Sudoku Grid, I just select the candidate I wish to choose, highlight it, and change its color. That makes it easy to see which candidates I have selected in all of the cells.
And I do remember to mark the first cell with an asterisk so that I know which pair of candidates contained either a correct or an incorrect choice.
I admit that I don't really enjoy using Forced Choice, but it definitely does make it possible to solve some more difficult puzzles.
If lines are drawn along the rows and columns, connecting the squares involved, they can form two rectangles, connected at the corners.
This resembles the wings of a biplane, separated by struts. A swordfish is found when for three rows, there are two or three possible squares in which a particular number can be placed, and for all three rows these squares lie in the same three columns.
In this case, this particular number can be eliminated as a possibility for all other squares in those three columns. To give you a good chance of spotting the swordfish you should enter all the pencil marks in the grid as shown here.
There are no easy routes to spotting the swordfish pattern. So, try focusing on just one number in turn as you scan your pencil marks in rows and columns.
Empieza a jugar ya. No debes olvidar que un movimiento es incorrecto si:. Una vez que se domina, el sudoku es un divertido juego de puzle. Sin embargo, aprender a hacer sudokus puede resultar un poco intimidante para los principiantes.
Look at the rows that feed into that row or square — sometimes you will be able to eliminate one number or the other, and can quickly fill in the gaps.
If a number already exists in a row or square, then that number cannot be placed again. For example, if the top row of a Sudoku puzzle already has the numbers 1, 7, 8, 5, 9 and 2, this means that the row still needs numbers 3, 4, and 6.
Look in the nearby rows within the same squares to see if you can rule out any of those three missing numbers. What do I know now, as a result of having placed that number?
Every single time you place a number, it gives you an opportunity to potentially place more numbers in nearby rows and squares depending on which other numbers in those places are already known.
