So, how to solve Sudoku.The rules are very simple and clear, easy to remember them.But do not think that the simple rules promise "painless" solution;will have to think a lot, apply a logical and strategic thinking, seek to recreate the picture.Probably, it is necessary to love the numbers to solve Sudoku.
first is drawn square 9 x 9 cell.Then, more bold lines, it is divided into so-called "regions" of three squares each.The result is a 81 cell, which ultimately must be completely filled with numbers.Therein lies the difficulty: placed around the perimeter of the digits from 1 to 9 must not be repeated either in "regions" (3 x 3 squares) or in the lines vertically and / or horizontally.In any Sudoku initially present some filled cells.Without it, the game just is not possible, because otherwise will not reveal all, and inventing.From the number of digits depends on the complexity of the puzzle.Difficult Sudoku contain some numbers, often arranged so that have pretty smash his head before deciding them.In the light - about half of the numbers are already in place, so to unravel becomes easier at times.
completely disassembled example
is difficult to understand how to solve Sudoku, if there is no particular pattern, showing step by step how, where and what you need to insert.Granted considered a simple picture, as many mini-squares are already filled in the necessary numbers.By the way, it is to them we are going to build for the decision.
You can start to see the lines or squares, especially where a lot of numbers.For example, the second column is perfectly located on the left, there's not enough just two numbers.If you look at the ones that are already there, it is clear that not enough 5 and 9 in an empty cell on the second and eighth rows.With the quintet until everything is clear, it can be there, and there, but if you look at the top corner - everything becomes clear.Since the second line already have the number 9 (in the seventh column), so that there is no repetition, nine need to put down at 8 th place.By process of elimination adding 5 to the 2nd row - and here, we already have one filled column.
a similar manner, you can solve all the Sudoku puzzles, but in more complex cases where the same column, row or box is missing a pair of numbers is not, but much more will have to use a slightly different method.And we have also now face it.
This time we take as a basis the average "region", which lacks five numbers: 3, 5, 6, 7, 8 of each cell are not we fill large numbers of productive and small, "rough."Just write in each square the figures are missing, and that may be there because of their lack.The top cell is a 5, 6, 7 (3 this line is already in the "region" to the right, and 8 - left);left in the cell may be 5, 6, 7;in the middle - 5, 6, 7;Right - 5, 7, 8;below - 3, 5, 6. Okay, now look what a mini-figures contain a great number of others.3: There is only one place in the other it is not.So it can be corrected to a large.5, 6 and 7 have at least two cells, then, we leave them alone.8, there is only one, then the other digits disappear and you can leave eight.
alternating these two methods, we continue to solve Sudoku.In our example we will use the first method, however, it should be recalled that in complex variations of a second is necessary.Without it will be extremely difficult.
Incidentally, when the upper "region" Seven Median discovered, it can be removed from the mini-figures mean square.If you do, you will notice that in the region there was one 7, so you can just leave it and.
That's it;the finished result:
Types
Sudoku puzzles are different.In some prerequisite is the absence of identical figures not only in the row, column and mini-squares, but also diagonally.In some instead of the usual "regions" contains other figures, which is why to solve the problem becomes more difficult at times.Anyway, how to solve Sudoku, at least, the basic rule that is valid for any kind of, you know.It always helps to cope with the conundrum of any complexity, the main thing - to try my best to achieve this goal.
Conclusion Now that you know how to solve Sudoku, but because these puzzles can download from various sites, to solve them online or buy at newsstands paper options.In any case, now you will have activity for hours or even days, because delaying Sudoku unrealistic, especially when you have to actually understand the principle of solving them.Practice, practice and practice again - and then you will be snapping this puzzle like peanuts.
