If you're tired of the 9x9, try the 16x16. A little easy, but still worth a try.

And when you're done, try a 16x16 hexdoku. It's a little different from your normal Sudoku.

25x25 sudoku.

EDIT 2: Erm...100x100 sudoku, anyone? O_o

To solve, left-click on a square to select the numbers from 1-100, and right-click to go back the other way.

My friend is going to try making a 144x144 Sudoku puzzle.

I'll call him next year when he's done.

I have a reward for the first person to finish the 100x100 Sudoku.
