## 9 Great Sudoku Facts You Probably Didn’t Know

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

1. Sudoku became a worldwide hit in 2005. When measured in its popularity in an enigmatic world, it’s the biggest phenomenon since the Rubik’s Cube in the 80s.

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

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

4. Puzzles have a large amount of possible combinations and levels of complexity. There are 6 sextillion possible puzzles, but only 5,472,730,538 of them are valid (when reduced to essentially different solutions) and it would take you a few lifetimes to solve them all. There are many difficulty levels (at least 5, even if it’s an arbitrary number) and there are enough challenges for any game skill.

5. This is not a math game at all, there is no calculation to do – it is pure logic game. Sudoku is semantically independent and can be easily understood by players around the world unlike good old crossword puzzles which have to be adapted to each language. The best part of all is that sometimes Sudoku 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 one in 2008 in Goa, India. In 2009, it will take place in Slovakia.

7. Some people call it the newspaper saver because it increases their sales and keeps the readership active. Newspapers around the world adopted it immediately because people love solving Sudoku everyday, just like crossword puzzles.

8. By playing it regularly, you can increase your focus and concentration, prevent or relieve depression, dementia, and even Alzheimer’s disease according to some studies. Sudoku is suitable for all ages between 6 and 120 years old, as it develops mental abilities and keeps them in good condition. It is a highly addictive game without any side effects and even though it can deeply involve a person, their brain will be grateful.

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

Conclusion:

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