What is a good way to improve my sudoku-solving skills?
Q. All my friends are fantastic at sudoku and they LOVE it, but i don't, mainly because well, I can't solve those things. I just want to know for those sudoku solvers out there how do you solve them, is it natural ability, patience, or secret formula that I don't know about...? Thanks.

How does a computer generate sudoku puzzles of different levels?
Q. How does a computer know how to generate an "easy", "medium", or "hard" sudoku? The number of filled-in squares does not describe the level of difficulty.

A. part of it is the total number of blank squares that they start you off with.

How does one go about solving a Sudoku cube?

A. WARNING this guide only works if your cube has ALL centers as 5's. Sorry for lengthy guide if this is not your case, I have warned you. Hmm, if you know the process of solving a regular cube using the layer-by-layer method. I used to own a sudoku cube, and it really wasn't sudoku where you had to avoid every line, just get 1 of each number on each side, (which I thought sorta ruined the point) but it had a 5 on each center so it would have been impossible... Now, for the first side, remember the even numbers, 2-4-8-6, find those edge pieces (have 2 numbers on them) and position them on the top side so that they run counter clock wise. Make sure you have those pieces that also have another 2 on them. Now, fill in your corner piece, so… [cont.]

How many possible ways are there to fill a Sudoku-2 puzzle?
Q. A Sudoku-2 puzzle is similar to the usual Sudoku puzzle, except for the fact that it includes 16 squares on a 2*2 board, rather than the 9*9 one, and it's played in the same way (of course you can only use numbers ranging from 1 to 4). I have estimated the possible results of a solved Sudoku-2 into 4*3*2*3*2*2*2 = 4!*3!*2!*2 = 576 but I have followed a heuristic method and I have not been able to find a way to prove it mathmatically. Is the result correct? And if it is, is there a way to prove it? Note: I have noticed that some of you have answered that there is only one way to fill a Sudoku-2 puzzle.

What is the least number of numbers needed to be given in order to determine a sudoku puzzle?
Q. I mean What is the least number of numbers that is needed to be given in a sudoku puzzle in order to determine exactly one solution. =p Explain your answer please lol.
Asked by s0nic213 - Thu Apr 5 16:32:28 2007 - - 3 Answers - 0 Comments
A. Going for "least needed", 17 is the least that has the potential to define a unique 9x9 fill. Going for "most needed", it should be possible to have a 2x2 that can flip either way, so that 77 squares could be filled and still have a duplicate solve, so 78 would be the magic number to force a unique solution. I'm not sure given your question which of these answers you are looking for.

I just don't know if they are accessible enough to just "spot" them as you work through.

What is the minimum quanity of numbers a sudoku puzzle must have at start and yet still only have one solution
Q. If you attempted to solve a sudoku puzzle that only had one blank square then it would be the easiest sudoku possible. On the other hand, a sudoku puzzle with 80 blank squares is almost equally as easy because there are thousands of possible solutions. There must, therefore be an optimum quantity of "starter numbers" that constitute the hardest possible sudoku puzzle by having only one possible solution and yet having the minimum of clues. Additionally i would love to see the maths behind the answer.
