No it's not... but sometimes with computers even the impossible is possible with a certain amount of dedication!\n\nThere is a group who are interested in arcade games that have been wrestling with this very problem, and have started to come up with some solutions it would appear.\n\nLinks to their pages are below - maybe amongst their codes and notes there is something that will help you out.

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).

Follow the method from the other 4 problems that you just posted.\nIn order to learn, you have to try things yourself.

I think Sudoku is wicked. I like the Lotto Sudoku better!

Fermat's Last Theorem has been solved ashas the Four Color Theorem. The Poincare conjecture has recently been solved. Trisecting a general angle with unmarked straightedge and compass has been shown to be unsolvable (although it is possible with marked straightedge and compass).\n\nHigh on the list of open problems:\n\nRiemann Hypothesis.\nP=NP?\nTwin prime conjecture.\nAre there any odd perfect numbers?\nProof of existence of solutions to Navier-Stokes equations.
