If you were a subscriber to Sudoku Pro then you can still get hold of issue 50, which so far as I know wasn’t received through the post (but I could be wrong).

Anyway, using Google’s page cache I’ve retrieved the previously-published URL:

Note that to use this you will need your subscriber number, which was on the bit of paper with your delivery address. Enter that in the top box, and your surname in the bottom box.

It’s still working as of right now, at any rate.

And here’s the previous issue 49, also thanks to Google: http://viewer.zmags.com/auth.php?magid=198026

I can’t imagine these will keep working too much longer, but who knows?
