Can somone plz tell me wat type of logic is used for solving SUDOKU puzzles??

Its obviously problem solving, because the whole sudoku is a big proble (puzzle). Its like a math problem. Therefore you need the problem solving skills (loogically)

I am a Sudoku addict, is that what you mean?\nIf you mean like ice breaker games I have tons cause I used to be a camp counselor. Here is one idea for a party.\nFor each team you'll need one T- shirt and one plastic storage bag. Place one nicely folded T-shirt in each bag then pour in about 2 cups of water and freeze all of them overnight. If this wasn't done where the event is taking place bring the T-shirt in a cooler filled with ice to keep them frozen. Instruct the teams that they'll be playing an Ice Breaker game. Then hand out the bagged T-shirts to each team. On "Go" the teams will have to get their T-shirts thawed out so that one person from their team can put the T-shirt on. Teams will get creative in their attempts to win. They could run the shirts underwater, put them in the microwave and even pounded the ice out of them. The first team to come back with one person in the T-shirt is the winner.

I have heard of Sudoku. My father introduced me to the game. I can't say I am addicted to it yet but I do enjoy solving one or two occasionaly. \n\nIf you are addicted to it check the link in the sources. It offers thousands of free puzzles.

Can you please check you haven't made a mistake somewhere? I have just calculated (with 99% certainty) that there are no solutions to those equations with those restrictions.\n\nEdit - OK, I assumed you made exactly one mistake. By removing each possible word and trying to solve it, I discovered that removing 'SIGH' was the only option that gave an answer.\nt 1\nh 8\na 3\nn 7\nk 6\ns 5\ng 9\ni 4\nv 2\nwhere SIGH = 26, not 25. Then THANKSGIVING = 65.\n\nThat was actually a cooler puzzle that the original, assuming you made one mistake :)

well here is the one I have coded.\n\ngo to www.geocities.com/mr_kamaal_khan\n \nand then in the Download section, there is a sudoku cracker.\nBut u need microsoft .net framework in order to run it. U can download that from microsoft site if u dont have.

What do you want to solve for? x? y? or do you want an ordered pair (x,y) that works (integers maybe?)

Logic puzzles is one way.  Anything involving computer programming, or even just macro writing, is good for logical thought and analysis.  Chess is excellent, as are many other games.  Look for games of pure reason, where chance is not a factor, or games of chance where calculating the odds is important.  \n\nRead.  Read whatever interests you, but go for the very best of whatever category you like.  Mysteries are especially good for developing reasoning: can you figure out who dunnit before the detective in the story does?  (Which reminds me, speaking of games; play Clue!)\n\nAnd of course, Yahoo! Answers will help a great deal, if you take it seriously.  Enjoy the jokes and riddles, but don't waste your time with those who ask dumb questions just to see if they can get a laugh out of the answers.

The puzzles are excellent for developing logical thinking skills and developing problem-solving strategies. They also develop patience, persistence and concentration. Last but not least: the sense of satisfaction at solving a super dooper mondo killer difficult puzzle makes me feel as if I'm THE smartest person in the world.

There used to be a lot of them, but with computers these days they are being solved by brute force. Examples include Fermat's Last Theorem and the Four Color problem in topology. You can look those up to see what they are, and you will probably find sites listing other unsolved mathematical puzzles.

You place all 9 squares. There are 9! ways to place the pieces(without being concerned about each pieces orientation)\nFor each of the 9!, each piece can be rotated into 9 positions. So there are going to be 4^9 possiblities.\n\nOnce you find the correct solution, you can rotate the entire puzzle 90 degrees 4 times.\n\nso the correct number is 9!* 4^9 /4\n9!*4^8\n= 23,781,703,680\n\nNOTE--To the people who are answering 9!*4^9\nWhat would the possible solutions be if there was only one piece?\nWould it be 1!*4^1 =4\nNo, it would be 1/4 of that.\n\nIf there is a similar puzzle of NxN size\nthe solution would be (N^2)! *4^(N^2 -1)

The web site I give below has some tips to get you started.  If you google (or yahoo!) for "sudoku" you'll find plenty of material.

Sudoku is a neat game of logic.  No math skills are needed other than recognizing the numbers 1 to 9, although there are more complicated versions now that use a grid larger than 9 x 9.  Games range from very easy to very difficult.  As with most games now, you can play on line if you choose.  It is VERY addicting!!  Here are a few links that might get you started if you want to learn to play Sudoku.  Also, check your local newspaper.  Many now carry a sudoku puzzle everyday.  Have fun!

Wikipedia has lots of good details on Sudoku including manual algorithms for solving, as well as computer algorithms.  I wasn't sure which one you wanted.\n\nFor solving it yourself, the most obvious way to start it by eliminating rows and columns for a region until there is only one choice for where a digit goes.\n\nFor computer solving, there is the brute force depth-first search known as Ariadne's thread.  It essentially tries a solution and keeps going until it finds an inconsistency, then it backtracks.  Other methods follow the human style of solving by putting all possible numbers in each square and then eliminating them until there is only one choice.  This then cascades to affecting other squares, etc.

hmmm....I looked through my text and course notes (I'm taking digital logic design this term) and I can't find a thing.\nIs there another name for it?\nTry google?\nAnyway, when you find out, I'd like to know!\n\nAdios.\n\nPS. helpful it would be if you mentioned whether this was software type logic or digital type logic (like combinational logic and exor gates)...
