... but i wonder how many grid combinations there are with a 16x16

[Pi]

lots?

I reckon more than there are in 9X9

Guenter has an estimate of 1e107, see http://en.wikipedia.org/wiki/Mathematics_of_Sudoku.

I'm wotking on 12*12 (dividing the grid into boxes of size 4x3). I'll guess that the 16*16-sudokus need lots of years to complete, and will never be done even with a revolution in algorithms and hardware.
