Sudoku Help - Puzzle creation options

We offer many choices of type of Sudoku puzzle for you to solve. Some other solvers offer no options at all.

You can select whether you want to generate a new unique Sudoku using File | Generate New.... It generates a brand new one each time - as there are billions to choose from. Alternatively you can download a Sudoku puzzle from this web site, which lets you play the same game as other people and you can use the discussion boards on our web site to discuss your experiences of solving it. Use the File | Download Puzzle... command to download a new puzzle including the current daily puzzles on our web site.

If you want to solve a puzzle printed in a newspaper or magazine you need to start with a blank grid that you create with the File | New Blank... or toolbar button. After you have copied in all the square allocations you should immediately save the game using File | Save as that sets the initial grid to use when you restart the game later on.

We support a range of grid sizes, by far the most often used is the standard 9 x 9 grid. The smaller grid sizes from 4 x 4 up to 8 x 8 are useful for learning the basics of Sudoku. Larger grid sizes are possible too, but 16 x 16 and 20 x 20 are the super-sized ones that we offer as a challenge for the dedicated puzzle solver.

There are a number of Sudoku variants supported: Standard Sudoku; Include a stripe; Diagonal; Hidden word; Chinese numbers and Jigsaw/Squiggle versions.
