We had a lot of fun giving away daily neatorama prizes this month! We hope you continue to enjoy this new aspect of the game. Thanks for being active on the Facebook page. Head over there to find out if you're a random winner, as we just announced that. Meantime, congrats to our first place winners Chelsea Tymms and Alexi Runnels:

We're so excited to win this month! We're both longtime mental_floss fans, but only discovered HDYK a few months ago - and we're so glad we did! It has definitely made the end of each month more exciting!
We are currently both in our second year at the University of Florida. Alexi is majoring in Biology and spends her spare time sleeping, reading, and creating elaborate Sims families. Chelsea is majoring in Computer Science and Mathematics, and enjoys juggling, math, programming, and origami (this is a picture of us in front of the level 3 Menger Sponge that Chelsea's honors Origami class created - from 48,000 interlocking business cards - last semester). We also enjoy cooking, playing tennis, and of course solving puzzles and learning trivia!
Thanks to David and Josh for coming up with such fun and challenging puzzles every month! We can't wait for the next puzzle hunt!

Final Answer

Jackie Robinson

Day 1

Day 1

Level 1

The primes are (from left to right for each row)
17, 593, 739, 17, 911, 773, 557,
97, 599, 359, 937
757, 191, 131, 997, 137, 79, 971, 151, 331
337, 179, 37
199, 113, 73, 571, 719, 59

Shading these numbers (except for 199, which is outside the word) forms the answer word, “cone.”

Day 1-2
Taking the first letter of each word, in order, spells out “WHICH HIDDEN IDEA CAN HDYK HUNTERS INTELLIGENTLY DECIPHER” – which, of course, is the first sentence of the paragraph itself!

This, here, is some hapless example (really excellent); I sincerely send our most earnest hopes – and please let echidnas surf soon!

Day 1-3
As cryptogram fans, we were good at this one. (We worked around the “ND” in “142ND” first, and that helped us realize the one that was “AMERICAN IDOL.” Everything else followed pretty easily after that, though we had to Google some names.

Name column (top to bottom):
1.SPAIN
2. LEE DEWYZE
3. DROSSELMEYER
4. THE SOCIAL NETWORK
5. ROBERT KIPRONO CHERUIYOT

Award column(top to bottom):
A. 4 GOLDEN GLOBES LAST WEEK
B. BOSTON MARATHON IN 2:05:52
C. AMERICAN IDOL SEASON 9
D. 142ND BELMONT STAKES
E. 2010 FIFA WORLD CUP

Matched up using my letter/number scheme, the pairs are 1-E, 2-C, 3-D, 4-A, 5-B

And, using the cryptogram letters, EDHSBMR spells BALONEY

The answer to the Neatorama question was the home state of the 2011 Miss America winner: Nebraska.

Day 2

Level 1

SQUARE ROOT OF FOUR
HELIUM ATOMIC NUMBER
LOWEST US TV CHANNEL
QUARTS IN HALF GALLON
POINTS FOR NFL SAFETY

So the code to advance was SHLQP.

Day 2-2
A. It’s a famous picture of Julius Caesar being murdered (we suspected it was Caesar, and used Google Images to confirm this)
So the phrase is Caesar’s famous last quote, “Et TU, Brute?”
B. Is Buzz Lightyear, so the phrase is his famous quote, “TO infinity and beyond!”
C. It’s the last scene of the internet favorite OK GO music video, “This TOO shall pass”
D. It’s the band Boys II Men.

Day 2-3
1. Hungry Hungry Hippos
2. Yo-Yo Ma
3. Dance Dance Revolution
4. Yo Gabba Gabba
5. Chi Chi Rodriguez
6. Jar Jar Binks

The odd one out is Yo Gabba Gabba, since the double word occurs at the end, rather than the beginning. The Neatorama answer was the actress who’s the mother of twins Vivienne and Knox: Angelina Jolie

Day 3

Level 1

We suspected they were groups of first, middle and last names of US Presidents, and a search confirmed the ones we didn’t immediately recognize as middle names (Wilson and Jefferson).
1. Chester Alan ARTHUR
2. FRANKLIN Delano Roosevelt (or FRANKLIN Pierce)
3. Ulysses S GRANT
4. William JEFFERSON Clinton
5. James KNOX Polk
6. MARTIN Van Buren
7. Zachary TAYLOR
8. WARREN Harding
9. Ronald WILSON Reagan

So, group by last, first or middle name:
1,3,7 (1+3+7 = 11)
2,6,8 (2+6+8=16)
4,5,9 (4+5+9=18)
Answer:
18*11*16=3168

Day 3-2

We thought of a few ourselves, then used Google Instant to find and test the top suggestions for “three + [block].” The solution, from top to bottom:

NONBLONDES
TENORS
BLIND MICE
LITTLE PIGS
MILE ISLAND
BILLY GOATS GRUFF
MUSKETEERS
DOG NIGHT
STRIKES LAW
CARD MONTE

Day 3-3

1,1,3,2,2,3
2,3,2,1,3,1
3,1,2,3,1,2
2,3,1,2,1,3
3,2,3,1,2,1
1,2,1,3,3,2

The diagonal numbers are 132222, and the following Neatorama answer is the color besides cyan of 3D-glasses lenses: red.

Day 4

1. FERMI: – after reading a clever hint from the facebook page, I was looking for correlations involving newspapers and came across newspapers called the Berkeleyan and Californian. I thought “but no Einsteinian...” which made me realize the real connection:
Berkelium, Californium, and Einsteinium are the 99th, 98th and 99th periodic elements. The 100th element is fermium, named after Enrico FERMI.

2. COWBOYS: University of Phoenix, Raymond James, and Sun life are all football stadiums, and are the locations of the 2008, 2009, and 2010 Super Bowls, respectively. So the fourth word is COWBOYS, the name of the stadium at which the 2011 Super Bowl will be played.

3. BLUE: Cubism, African, and Rose are each one of Pablo Picasso’s major art periods. The fourth of his major periods was the BLUE period.

4. HORSE: Rabbit, Dragon, Snake are a sequence of Chinese Zodiac animals – the next one in the sequence is HORSE.

The letters, reading from top to bottom down the first letter of each pair, then top to bottom for the second letter in each pair, spell the phrase FOUR EYES.

Day 4-2
This one took a while, but it was fun!
Pictures’ words, in order:

Kebab
Ross
Glow
Beagle
Goldie (Hawn)
Bur
Hoagie
Albus (Dumbledore)
Spot
Globe
Spa
Goal
Parka
Bob (Barker)
Bo
Hoe

Bo+(Hoagie-Hoe)=Bogey
(Glow+Beagle)-Globe=Eagle
Bur+(Goldie-goal)=Birdie
Parka-(Kebab-Bob)=Par
[(Albus+Spot)-Spa]+Ross=Albatross

These are all names possible scores for a golf hole: Bogey is +1, Par is…par (0), Birdie is -1, Eagle is -2, Albatross is -3. Ranging from best score(and most letters) to worst score, the order is:

Albatross
Eagle
Birdie
Par
Bogey

Day 4-3

Gaynor hit: I Will Survive
Part of OCD: Compulsive
Aerial activity: Skydiving
Metamucil, for one: Laxative
Police investigator: Detective
Tron: Legacy costar: Olivia Wilde
Harry Potter address: Privet Drive
His name rings a bell: Pavlov
Organ affected by hepatitis: liver
Found through differentiation: Derivative

Fitting them by size and by position of the repeating pair of letters, “IV,” the correct order in the boxes is:
1. IVANPAVLOV
2. LIVER
3.OLIVIAWILDE
4.DERIVATIVE
5. SKYDIVING
6. LAXATIVE
7.DETECTIVE
8.COMPULSIVE
9. PRIVETDRIVE
10. IWILLSURVIVE

The year that Ivan Pavlov was “created” was 1849. It took a while to realize we had to spell it out to get to the correct Neatorama page!
neatorama.com/eighteenfortynine bore the riddle “How many letters does the correct one-word answer to this question have?” The correct answer, the only number whose value is the same as its number of letters, was FOUR.

Day 5

A: 18
B:75
C:131
D:3
E:12
FINAL ANSWER: Jackie Robinson
