Logic puzzles such as Sudoku are the
cherry on the cake when it comes to exercising the brain. Earlier,
oblivious to the world and only known to Japan, this game has
briskly expanded its footprints and has taken the shape of a
phenomenal fad. These addictive variations of the brain teasers
have become a common feature of newspaper puzzle pages, brain
storming books and quizzes. The game demands neither mathematical
ability nor general knowledge. The only skill required is
the ability to recognize the difference between nine different
symbols, and these don't necessarily have to be numbers. This is
one of the reasons why it has turned into such a runaway success.
What is Sudoku?
Sudoku puzzles consist of a 9 x 9 grid which is split up
evenly into nine 3 x 3 grids. Each row, column and 3 x 3 grid must
contain the numbers from 1 to 9 without repetitions of the numbers.
Some slots of the grid are provided with numbers; you are required
to solve the rest of the puzzle via logical deduction. Sudoku
puzzles can be very mentally demanding and are valuable as mental
workouts for part of your brain training routine. While there is no
substantive evidence that brain teasers actually improve intellect,
it is well proven that mental challenges help hone your sharpness.
However this in no way implies that the same challenges have to be
repeated over and over again. As you play a game the mind memorizes
the tricks and techniques and automates the way you play and
boredom settles. Thus it is important to move from one level to
another, always evolving your tricks and speeding up your action.
Some types of the common Sudoku are: Doof Sudoku -
Arrange the numbers so that they appear only once on each row,
diagonal row and column. Killer Sudoku - Is a puzzle that
combines elements of sudoku and kakuro. Hyper Sudoku -
Sudoku with overlapping regions
How Sudoku helps?
While playing Sudoku you need to look at the big picture and figure
out missing numbers that you can plug in the right places. You can
always time yourself and constantly try to outperform yourself.
Sudoku solving, trains your mind to process various forms of
information, details, images and strategies at lightening speeds.
While you devise strategies to win the game, it also builds your
neural connections. It helps in extending dendrite connections in
your brain cells which help improve memory. Scientists say solving
them depends on neural pathways that even the most powerful
computers can't replicate. They say that by studying how people
solve the puzzles, we might be able to develop more intelligent and
brain-like computers. Which attributes are developed or sharpened
while playing Sudoku? To crack Sudoku our brain uses a
unique set of neural pathways known as associative memory, which
equips us to identify a pattern from a partial clue. We all
recognize the basic pattern of counting digits from 1...9, yet the
task of completing a Sudoku puzzle is confounded because of the
large number of possible permutations of this pattern. But every
time we plug the right digit in the correct slot it provides us
with a clue, which reduces the number of permutations and
simplifies the task. Thus Sudoku is a marriage between logic and
intelligent guesswork based on the abilities of associative memory.
The pre-requirement is that you can solve a Sudoku!
As long as you can solve a Sudoku, you can make a Sudoku.
if you can solve an easy Sudoku, you can make an easy Sudoku.
If you can solve a medium Sudoku, you can make a medium or easy Sudoku.
If you can solve a hard Sudoku, you can make a hard or medium or easy Sudoku.
At Create Sudoku, all the Sudokus are solved using
a list of methods, from simple to hard.
We measure the difficulty level of a created Sudoku based on
methods that have to be used to solve it, assuming that a
Sudoku solver always uses the solving techniques from
the easiest to the hardest.
She/He only uses an advanced solving method when easier solving methods could not solve it.
Some well-known techniques to solve Sudoku puzzles, from the easiest to the hardest, are
OneChoice, Elimination, interaction, subset, X-wing, XY-wing, XYZ-wing,
We rate OneChoice and Elimination as easy solving techniques;
Subset, X-wing, XY-wing, XYZ-wing as medium solving technique;
Guessing as a hard solving technique;
and Search as the most challenging solving techniques.
An easy Sudoku is one that can be solved without listing candidate
digits of empty squares.
A medium Sudoku is one
that must be solved by multiple rounds of more advanced
methods , including Subset, SubsetPosition,
Interaction, X-wing series, XY-Wing, and XYZ-Wing besides easy solving techniques.
To solve a medium level Sudoku, you will have to list
candidate digits of empty squares.
