Contest 1: Attack of the Four Puzzles!

Do you want to win high-quality logic puzzles imported from Japan? The Attack of the Four Puzzles! contest might be your opportunity to do just that! The four short sections below explain all of the details.

How to enter:
This contest consists of a four-part logic puzzle (below). To participate in the contest, solve the puzzle, obtain the final answer from part iv, and e-mail the answer to glmathgrant[at]gmail[dot]com. Only one entry is allowed per person; however, if you believe your answer is wrong, you may change it at any time before the deadline. The deadline is two weeks from the time the contest started (that is, October 20, 2009).

How to win:
After the deadline has passed, the winner will be randomly selected from all of the entrants with the correct answer. Therefore, to win, you must both be skilled enough to solve the puzzles before the deadline, and lucky enough to be picked. (But even if you're not lucky, hopefully you'll have had fun solving the puzzles, right? :) )

Prize:
The winner will receive his or her choice of either 3 of Nikoli's Pencil Puzzle Books, or any 1 or 2 Nikoli books whose prices total at most 2100 yen (see this link for a list of all of the books Nikoli has available). Each Pencil Puzzle Book contains about 96 puzzles of one particular type, which is great if there's a certain puzzle type you particularly want to focus on; if you'd rather have a wider variety of puzzles available, books like the Penpas Mix series, the Puzzle Box series, and the Puzzle the Giants series will satisfy your needs perfectly. Either way, you win! :) When you win, provide me with your mailing address and which books you'd like; I'll pay Nikoli to have the books shipped directly to you.

Terms:
By entering the contest, you agree to the following terms:
a) You are prepared and willing to provide me with a mailing address in the event that you win. (In return, I agree not to use your mailing address for any malicious purposes, such as sending junk mail or other undesired things.)
b) You are prepared and willing to wait several weeks for the books to arrive from Japan (this contest is mostly for fun, anyhow -- and high-quality puzzles are worth the wait, right? :) ).

Now that you're done reading all that, here is the four-part contest puzzle. Good luck! :)

This was a fun set of puzzles. I liked how they were linked together through part 4. It's nice to see something a little different like that. Thanks for this and all the other puzzles -- they're a good supplement to my Nikoli books. :)
