The 'G' QI Annual featured the fiendishly challenging Sudo N'Ko puzzle. Sadly, since the annual was so full of interestingness, there was no room left to publish the answer to the puzzle.

But fear not, for you can check your results right here. We trust that you're checking that your completed puzzle is completely accurate, rather than sneaking a peek at the answer to try and impress your friends when you claim to have finished the puzzle all on your own.
