Did you solve it? The pain and pleasure of Japanese puzzles

The solutions of today's puzzles, and the results of the Nikoli Derby.

In my column earlier today I set five examples of a new Japanese puzzle called Snake Place and we also played a re-run of the Nikoli Derby, where I asked you to submit a number, with the winner being the person submitting the lowest number that no one else also submits.

The solutions to Snake place can be seen here (on a printable page).
