A Brain Teaser Called Sudoku Puzzles

Sudoku Puzzles are brain teasers that have also been called wordless crossword puzzles. Sudoku Puzzles are often solved through lateral thinking and have been making a large impact all across the world.

Also known as Number Place, Sudoku puzzles are actually logic-based placement puzzles. The object of the game is to enter a numerical digit from 1 through 9 in each cell that is found on a 9 x 9 grid which is sundivided into 3 x 3 subgrids or regions. Several digits are often given in some cells. These are referred as givens. Ideally, at the end of the game, every row, column, and region must contain only one instance of each numeral from 1 through 9. Patience and logic are two qualities needed in order to complete the game.

Number puzzles very much similar to the Sudoku Puzzles have already been in existence and have found publication in many newspapers for over a century now. For instance, Le Siecle, a daily newspaper based in France, featured, as early as 1892, a 9x9 grid with 3x3 sub-squares, but used only double-digit numbers instead of the current 1-9. Another French newspaper, La France, created a puzzle in 1895 that utilized the numbers 1-9 but had no 3x3 sub-squares, but the solution does carry 1-9 in each of the 3 x 3 areas where the sub-squares would be. These puzzles were regular features in several other newspapers, including L'Echo de Paris for about a decade, but it unfortunately disappeared with the advent of the first world war.

Howard Garns, a 74-year-old retired architect and freelance puzzle constructor, was considered the designer of the modern Sudoku Puzzles. His design was first published in 1979 in New York by Dell, through its magazine Dell Pencil Puzzles and Word Games under the heading Number Place. Garns' creation was most likely inspired by the Latin square invention of Leonhard Euler, with a few modifications, basically, with the addition of a regional restriction and the presentation of the game as a puzzle, providing a partially-complete grid and requiring the solver to fill in the empty cells.

Sudoku Puzzles were then taken to Japan by the puzzle publishing company Nikoli. It introduced the game in its paper Monthly Nikoli sometime in April 1984. Nikoli president Maki Kaji gave it the name Sudoku, a name that the company holds trademark rights over; other Japanese publications which featured the puzzle have to settle for alternative names.

In 1989, Sudoku Puzzles entered the video games arena when it was published as DigitHunt on the Commodore 64. It was introduced by Loadstar/Softdisk Publishing. Since then, other computerized versions of the Sudoku Puzzles have been developed. For instance, Yoshimitsu Kanai made several computerized puzzle generator of the game under the name Single Number for the Apple Macintosh in 1995 both in English and in Japanese language; for the Palm (PDA) in 1996; and for Mac OS X in 2005.

A Sudoku A Day Exercises The Brain

Negative issues are usually associated with addiction. Drug abuse, excessive drinking, and even too much gambling are all negative activities that are highly addictive. But if there is one kind of addiction that is actually beneficial for adults and kids alike, it would be an addiction to sudoku puzzles. Researchers rank solving sudoku puzzles daily among the top ten non-traditional and alternative ways to boosts brain power. Other brain boosting moves include high-protein diets, listening to classical music, and lots of rest. These are simple but are rather difficult to follow because of budget limitations, personal preferences, and lifestyle. This is the advantage sudoku games holds over other brain boosters. They are accessible from newspapers, books, and even the Internet. They are also workable between breaks or at any spare time. So every time someone chastises you for doing sudoku again, kindly explain and hope that they pick up the habit too.

Though sudoku puzzles are not mathematical problems, solving the puzzles requires the most basic tool of mathematics and science: logic. Since the puzzles entail the use of logic, common sense, and concentration, the brain is put out of the stupor of doing routine, mundane tasks. In other words, your brain actually gets a break and a good work-out. Studies reveal that the more the brain uses its skills, the better it works. Brains that get more exercise are determined to be more active, and its cells are healthier. Researchers even associate sudoku brain exercises to physical exercise. They stress that just as physical exercise keeps muscle loss at bay, sudoku exercise keeps brain cells from dying and also encourages better brain function. Education is important, but studies actually show that students who do mental workouts like sudoku have higher IQs than students who do not. This only shows that doses of sudoku are more than just ways to pass time. They actually help in improving your ability to comprehend more complex ideas.

Ian Robertson, a neuroscientist, facilitated a research among the elderly with the premise that decreased mental ability is not inevitable with the right stimulation. The research included two groups of elderly people: the first group solved sudoku puzzles as part of their routine, while the second did not. After some time, their IQ levels were tested and compared to their test results before the experiment. The sudoku-solving group was found to have increased their mental abilities by a significant percentage while the other group showed no change. Dr. Robertson cited a similar research wherein 3,000 people, aged 65-94, were found to have increased their mental capabilities and age by as much as 14 years, just by ten sessions of brain boosting exercise like sudoku.

Other experts agree with these findings, saying that solving challenging mind games like sudoku puzzles inhibit or prevent the development of Alzheimer's disease and memory loss. Health trends also show that adults with demanding, and intellectually challenging jobs benefit from better mental function when they age. Sudoku functions just like these jobs because it requires brain exertions.

As it is, experts advise adults to encourage children to solve puzzles like sudoku to start mental improvement earlier in life. Sudoku exercises are actually adopted by some schools to stimulate thinking and foster better academic performance of their students. So instead of letting kids watch TV, or read comics, hand them sudoku puzzles. Then, both you and your kids can defend your love of sudoku to those poor souls who do not understand the beauty, joy, and benefits of solving it.
