Puzzle 101

 * Name: Shy Guys and Gals (US) / Shy Lads and Lasses (UK)
 * Trigger: Talk to Misha
 * Location: Chinatown Gate
 * Chapter: 10
 * Picarats: 30

Description: Four shy couples are depicted below by red and blue symbols. They would all like to meet up with their respective partners for a date without running into anybody else in town. Draw lines between couples A-a, B-b, C-c, and D-d without crossing any of their paths.


 * Hint 1: Think carefully about the detours the couples need to take to avoid crossing paths. They can't all just take the shortest route to each other.
 * Hint 2: Couple D-d's path to each other takes only one turn.
 * Hint 3: Couples B-b's and C-c's paths to each other take four turns. Couple A-a's path takes three turns.
 * Super Hint: Couple D-d's path to each other follows the right edge and the bottom edge. A walks straight down until just before D, then takes a left. B and C both start out by going one block to their right. Couple B-b's path wraps around beneath couple C-c's. Couple A-a's path is below B-b's. Give it another shot will all that in mind!

Puzzle 102

 * Name: Balance Your Books
 * Trigger: Talk to Maya
 * Location: Bookshop
 * Chapter: 10
 * Picarats: 30

Description: You recently bought several rare books at a used-book store. The total you paid, before tax, was 99 pounds. The image below shows the shelf you purchased your books from. Below each book is a tag listing its price, also before tax. Which books did you buy? Mark all the books you bought before submitting your answer.


 * Hint 1: The last digit of 99 is nine, so figure out which book prices add up to a number starting from 9.
 * Hint 2: Once you've figured out some combinations that add up to a number starting from nine, focus on finding a combination that results in a number ending in nine.
 * Hint 3: You bought four books. If your solution is more or fewer than four books, check your math and try again.
 * Super Hint: If you choose only those books that are priced as multiples of three, you'll have the right answer.

Puzzle 103

 * Name: Pool Problem (US) / Fill the Pool (UK)
 * Trigger: Talk to Hardy
 * Location: Behind the Casino
 * Chapter: 10
 * Picarats: 25

Description: You want to fill up your pool, but all of the valves between the tank and the nozzle are rusted shut. You only have three extra valves to work with. Tap the three valves you will replace to get the water flowing.


 * Hint 1: You need to replace one of the three valves that stop the water when it first leaves the tank. The one you're looking for is either the middle valve or the bottom one.
 * Hint 2: The next valve you need to replace is the one closest to the correct option from Hint One.
 * Hint 3: After you've replaced the valves in Hint One and Two, finding the last one should be easy. Find the path to the nozzle with the least amount of valves in the way.
 * Super Hint: If you've replaced the correct valves from Hint One and Two, the last valve is the one at the bottom left. That's three valves now. You're done!

Puzzle 104

 * Name: The Cake Gobbler
 * Trigger: Talk to Raleigh
 * Location: Statue Plaza
 * Chapter: 10
 * Picarats: 30

Description: "Hey! Somebody ate my piece of cake! I was saving that for later!" A: "I didn't eat it!" B: "Neither A nor D ate it." C: "I didn't eat it, either!" D: "C is telling the truth." Somebody isn't telling the truth. That person is the cake gobbler. Who is it? Circle the answer, then tap Submit.


 * Hint 1: Compare all the statements carefully. Did you notice that if A is lying, then B would also be lying?
 * Hint 2: If D is lying, then C would be lying. If C is lying, then D would be lying. Also, you'll soon realize that if B is lying, there is more than one cake eater and therefor more than one liar. Are they all liars?! No. Only one person involved in this puzzle is lying.
 * Hint 3: Out of A, B, C, and D, maybe nobody is lying... But somebody ate the cake!
 * Super Hint: A, B, C, and D are all telling the truth. But somebody is definitely lying. Who else is there?

Puzzle 105

 * Name: The Fingerprint
 * Trigger: Talk to Inspector Chelmey
 * Location: Flatstone St. 2
 * Chapter: 10
 * Picarats: 15

Description: A fingerprint was recently discovered at the scene of an unsolved crime! Four prime suspects have been rounded up and brought into the station. Compare the fingers of suspects A, B, C, and D to the fingerprint shown beneath the magnifying glass, and identify the guilty culprit!


 * Hint 1: Don't jump to conclusions. Consider all of the options carefully.
 * Hint 2: C looks completely wrong.
 * Hint 3: A fingerprint left on a wall is actually a mirror image of the finger itself.
 * Super Hint: C and D are clearly wrong. Either A or B is a match. Remember Hint Three?
