SJE only works on 9x9 grid size, values like 9, 3, 81 are pretty much hardcoded in the source code.
I posted this thread some time ago:
various NxN (N≠9) jigsaw sudokus.
The inference is that the hardcoded values in SE can be modified for other grid/block sizes. I have a collection of SEs for personal use! However I have not released any of those because of the GPL license that accompanies SE, and I do not have the time to properly maintain/release all those versions. I'll stick to updating those I've released on GitHub...
