Sudoku puzzles come in a variety of shapes.  Most frequently Sudoku puzzles come in a 9 by 9 grid, which is made up of three 3 x 3 sub grids called regions.  These regions are also known as boxes, blocks, quadrants and other terms.

Some cells already contain numbers called givens or clues.  Your goal, as the player, is to fill in the empty cells.  Each cell must contain only one number so that each column, row and region contains the numbers 1-9 just once.  This is where the “single number” from the puzzle’s name comes from.

The difficulty of the puzzles can vary wildly, and the number of givens provided has no reflection on the difficulty of the puzzle.  A puzzle with very few givens can be very easy, just as a puzzle with lots of givens can be difficult.  The difficulty of the game depends on the positioning and relevance of the numbers.

Of course, you are not just limited to a 9 by 9 grid with Suduko puzzles.  4 by 4 grids with 2 x 2 regions have been used, as have a 6 by 6 grid with 2 x 3 regions.  The Times publishes a massive 12 by 12 Sudoku grid with twelve 4x 3 regions.

If you are seriously addicted then you can find even bigger puzzles to challenge your mind.  16 by 16 grids have been published, using 1 through to G.  If that’s not enough of a challenge for you then there is a 25 by 25 grid available to feed your addiction.

Of course, being such a popular puzzle, Sudoku now has many variants with every newspaper and publisher trying to out do each to gain readers, popularity and sales.

Some variants require that each region, column or row add up to a certain total.  Even three dimensional Sudoku puzzles have appeared to seriously challenge the addicted. 

Variants with letters instead of numbers have also appeared, though these are functionally no different from the numerical puzzles unless the letters spell something.  Some variants have the diagonals spell words, whereas the Code Duko by Steve Schaefer embeds an entire sentence into the grid.
