Sudoku is a globally addictive puzzle game and yet there are many lesser known facts about it. Let’s see the most amazing facts about Sudoku puzzles.

1. Sudoku became a worldwide hit in 2005. Measured by its popularity in an enigmatic world, it is the largest phenomenon since the Rubik’s Cube in the 1980s.

2. Sudoku is not originally Japanese, but an American game. Modern Sudoku was invented in the United States under the name “Number Place” (in 1979) and later popularized as “Sudoku” by the Japanese publisher Nikoli. The creator of “Number Place”, Howard Garns, died in 1989, before the game reached its worldwide popularity.

3. Most Sudoku games on the Internet (and even in the newspapers) show wrong puzzles, due to the laziness of the developers or the non-obvious complexity of Sudoku and there are fatal flaws in the Sudoku generators that do not make unique puzzles or miscalculate the level of difficulty.

4. The puzzles have a large number of possible combinations and levels of complexity. There are 6 sextillion possible puzzles, but only 5,472,730,538 of them are valid (when boiled down to essentially different solutions) and you would need a few lives to solve them all. There are many levels of difficulty (at least 5, although it is an arbitrary number) and there are enough challenges for any game skill.

5. It is not a math game at all, there is no calculus involved – it is a pure logic game. Sudoku is semantically independent and can be easily understood by players around the world, in contrast to the old crossword puzzles that must be adapted to all languages. The best part of all is that Sudoku sometimes doesn’t even come in numbers, but in pictures, letters, or symbols.

6. The first Sudoku World Championship was held in Italy in 2006. After that, in 2007 in Prague, Czech Republic and the last in 2008 in Goa, India. In 2009 it will be held in Slovakia.

7. Some people call it a newspaper saver because it increases your sales and keeps your readership active. Newspapers around the world immediately adopted it because people like to solve Sudoku on a daily basis, like crosswords.

8. By playing it regularly you can increase your concentration and focus, prevent or alleviate depression, dementia and even Alzheimer’s disease according to some studies. Sudoku is good for any age between 6 and 120, because it develops mental skills and keeps them in good condition. It’s a highly addictive game with no side effects of any kind and while it can get a person deeply involved in it, their brains will thank you for it.

9. There are many Sudoku players around the world, but no one really knows the exact number of them, because there are various Sudoku games: downloadable Sudoku for computers, Sudoku online and many others.


As you can see, there are many interesting facts about Sudoku. But the main point is to play these puzzles every day so that you can feel their magic. If you haven’t played Sudoku yet, it’s good to start now and join the global community of fans. If you play Sudoku, teach someone who doesn’t, because it’s a rare time in life to get an appraisal for putting a new addiction in someone’s life.
