Large Sudoku Puzzles - 16 by 16 Grid [Page 13 of 15]

Previous Index Next Next

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

As each row; column and region has 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 16x16 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.

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