For the renban groups example, in the middle shaded region, it contains the numbers 1-9 excluding 7. Does that mean that 1 and 9 are considered adjacent consecutive?

1 and 9 are not considered consecutive. The middle box actually contains four distinct shaded groups of two cells each, although I can see how it could be easily misconstrued :)

In the contest puzzle itself the regions are clearly distinct from each other, so this sort of mistake shouldn't happen there, in case you were worried!

How do I get the password for puzzles file? Is that from the Answer Submission Page link?

Yes, on the answer submission page there will be a button which starts your timer, and the password is revealed to you when you do so.

D'oh - thought I could take the puzzle this evening on American time, but the contest ends a few hours too early to make that feasible. Understood that this is the UK championship - but an end time of say 6:00 UTC instead of 2:00 UTC would give us one more evening on this side of the pond. :)

Thanks for organising this Sam. I am enjoying working through those I didn't solve in the time given. The odd-even-big-small was very elegant.
