Large Sudoku Puzzles - 16 by 16 grid [Page 11 of 13]

If you want a real challenge try the 16x16 sized puzzle grid. The rules are just the same as for the regular 9x9 sized grid and the same strategies can be used too.

With each row; column and region having 16 rather than 9 possibilities there are a lot more options to think through.

The Dragon also supports several other larger sizes than the standard 9x9 : 10x10; 12x12; 14x14; 15x15 and 20x20 as well as 16x16. All the same principles apply, we limit the puzzle size to 20x20 because on most PCs larger sizes are very slow to generate and difficult to read on the screen.

Sudoku Dragon supports this grid size in just the same way as the 9x9 grid. As there are more than ten symbols to reason about the hexadecimal numbers 0 to 9; A to F are used for symbols (or you can choose to use the letters A to P instead) . These larger puzzles can be contributed and downloaded from our web site.

For more on big grids, we have a big grid topic in our message forum.

Sudoku Grid 16x16

The larger puzzles can still contain our unique Sudoku stripe. On this occasion the software has generated a big grid with the stripe located in region Aa.
