When you have discrete, countable units, such as the symbols, in this case numbers, already present on the Sudoku grid, you have more or you have fewer .

When it's something you can't count, you have more or you have less.

I have more 16x16 grid sheets printed up for hexadecimal Sudoku, because those are the ones I copy from 'the net'.

I have fewer (currently none, actually) of the 9x9 (4 to a page) printed because I quit doing the 1-9 version so
