Sudoku is a mind-boggling and number-arranging labyrintian game from Japan and took Britain by storm. For more info go to the links others gave to you.\n\nI have just played one set and still unfinished. I played it in school and during my second play (I only play it during free time), I have managed to arrange three numbers in the set.\n\nWill continue later to share my way of playing. The Batman is now being aired.\n\n\nNow, let's continue. Sudoku consists of nine 3 x 3 squares which means that a whole Sudoku has 81 squares.\n\nTo play Sudoku, you must fill all 81 squares with the number 1 to 9 perfectly horizontally and vertically. Plus, do not forget that Sudoku is divided to nine divisions which are the 3 x 3 squares. \nIn each division, you cannot repeat a number in it and also must be filled with the number 1 to 9 in the DIVISION.\n\nTo play:\nFirst, choose a number to solve. Pick the number with the most quantity first for ease of playing.\n\nOnce chosen a number, you tick the places where it cannot be put (horizontally, vertically and based on the box).\n\nIf your number is 1 and 1 exists in a box, it means that you can only put another 1 next and before the original 1 in either the two boxes remaining.\nIf 1 is in the upper box, you only have to put in either in the centre box or the lower box.\nREMEMBER! Each box has 9 squares.\n\nExample (0) represents void: \n100\n000 \n000\n000\n001\n000\n000\n010\n000\n\nThere! To finish the game, just continue with mapping the number in any probable compatible boxes and then the other number followed by the other number.\n\nIf not compatible, just remap.\n\nEnjoy!

History of Sudoku and Killer Sudoku Variations \n\nAll of us, by now should have heard of SuDoku... if you haven't, you must have been living in a box. Or maybe it is the other way around, those of us that are hooked on SuDoku are now living in a box (in the form of a 9x9 grid).\n\nAnyway, if you have always wondered about how this little number puzzle came about, it actually first appeared in the U.S. in the May 1979 issue of Dell Pencil Puzzles & Word Games where it was called Number Place. It is believed to be the creation of a retired architect named Howard Garns, age 74 at the time.\n\nSeveral years later, in 1984 it was adopted by a puzzle group in Japan and named "Suuji Wa Dokushin Ni Kagiru" ("the numbers must be single") As it became popular, this was shortened to SuDoku (Su=number, Doku=single) and was trademarked.\n\nOther magazines in Japan, soon copied the puzzle but went with the more generic name Nanbaapureesu (phonetically "Number Place") and often just used the English spelling. Later when it was rediscoved in the U.S. and the U.K. it was titled "SuDoku" which leads to an interesting scenario. Japanese speakers call it by its English name (Number Place) and English speakers call it by its Japanese name (SuDoku).\n\nIf you are interested in reading more of the historical details or learning about numerous sudoku variations (including Killer SuDoku a.k.a. Samunamupure or Samunanpure, Greater Than SuDoku, Samurai SuDoku, Relay SuDoku, etc.) there are a couple links below.

Keep your brain active.  Do Sudoku puzzles and things that are challenging.  Also, keep things in balance.  If you work hard one day, play hard on another.  Try to keep things in perspective.  That should keep you sane....if not, enjoy the ride!

Sometimes - rarely - there are.  I have very occasionally come to the end of the puzzle with two numbers that could go anywhere in two squares, ie, 2 and 6 might be interchangeable.  Then I think I'm wrong, and will do it all again to be faced with the same outcome!

For a nine by nine square Sudoku problem (81 total cells), a minimum of 17 numbers must be given to find the unique solution. Graph theorist Gordon Royle has found approximately 10,000 non-equivalent (or unique) Sudoku problems. (Technically, though, Sudoku can be any size, say 16x16). These days, newspaper use Sudoku puzzles which have been created by computer algorithm, deemed inferior to hand-creation. And lastly, the game was not originally Japanese; it was invented in the UK.

Just randomly enter numbers according to the rules of the puzzle, but using a blank grid. Start with one or two per 9-square block. To make the puzzle difficult, only enter a few numbers, and add more to make it easier.\n\nIt should be quite simple for a computer program to make a Sudoku puzzle, since there are basic rules to follow. I'm sure the "made by hand" claim is for marketing purposes (though I'm sure it's true).
