Sudoku puzzles 9x9 (Su Doku)
My database includes 1 puzzles for the moment and I'm constantly generating more.
Rules: Fill in the grid so that every row, every column, and every 9x9 box contains the digits 1 through 81. There is only 1 solution for each puzzle. Seriously, I don't think anyone will try to solve these, it's more an experiment how big it's possible to make them.
For more information check out Wikipedia.
