Am I the only one having difficulty reading the recent Killer Sudoku
grids on Times Online? For example, the 6's often look like 5's because
the numbers are all so small and fuzzy. Enlarging the image doesn't
help as it doesn't sharpen the picture but only increases the size of the fuzziness.
Other than that, I must say that I really enjoy solving Killer Sudoku.
They're a nice variant from traditional sudoku.
