Puzzle 101

 * Name: Square Goldfish
 * Trigger: Talk to Marion
 * Location: Fish Lab
 * Chapter: 9
 * Picarats: 45

Description: Below is a goldfish-shaped toy. This toy has a trick to it: it can be split into four pieces, which can then be assembled to form a perfect square. How can the toy be divided such that the resulting pieces could be rearranged to form a square? Draw two lines dividing the goldfish into four pieces.


 * Hint 1: Try to visualize which parts can be made to form the square. You can only draw two lines, so significant portions of the resulting piece will need to fit together to form a square shape, right?
 * Hint 2: The length of one side of the finished square is equal to the diameter of the circle that forms the fish's head.
 * Hint 3: Both the dividing lines should be drawn within the fish's head. Can you work out where?
 * Super Hint: Draw two lines to make an X across the circle that constitutes the fish's head. You will have three quarter-circle wedges as a result. If you fit these into the grooves on the fish's tail, you'll have a perfect square

Puzzle 102

 * Name: Window Pains
 * Trigger: Talk to Jasmine
 * Location: Murray Street
 * Chapter: 9
 * Picarats: 25

Description: "I was carefully cleaning up the fragments of this broken window with my three friends. I picked up the first three pieces. My friends followed in turn, each picking up three more pieces than whoever went before them. In the end, there were still three fragments on the floor. How many pieces of glass were there to begin with?"


 * Hint 1: If you figure out how many pieces each person took, you should be close to the answer. Just make sure you don't forget any pieces.
 * Hint 2: Try reading the puzzle again. You already know how many pieces the first person took. You also know that each person took three pieces more than the person before them. Count out how many each person would have taken, and then add all the pieces together.
 * Hint 3: The first person took three pieces. Each person after that took three more than the previous person, so they had three, six, nine, and 12 pieces respectively.
 * Super Hint: Don't forget the three pieces left lying on the floor! Adding the pieces that were placed up to the pieces on the ground gives: 3 + 6 + 9 + 12 + 3. Now you've got your answer.

Puzzle 103

 * Name: Cogs & Pulleys
 * Trigger: Talk to Clarence
 * Location: North Ely Park
 * Chapter: 9
 * Picarats: 30

Description: You find a large machine in a warehouse. It looks like it could be some kind of complicated device for moving a bucket up and down, but all the cogs and wheels make it difficult to know which way to turn the handle. Can you work out which way the bucket will move if you turn the handle clockwise? Touch the arrow that points in the correct direction. All of the cogs and pulleys are in good working order.


 * Hint 1: Think about the direction that each cog will move, starting from the one connected to the crank. The direction that each cog moves will change depending on cogs, pulleys and ropes connected to it.
 * Hint 2: When two cogs connect, the second one will move in the opposite direction of the first in the chain. The pulleys will change the direction in which the rope moves. When a pulley is connected to a cog or another pulley, the direction will be reversed if the rope is crossed and stays the same if it doesn't cross.
 * Hint 3: The first cog with the crank handle attached to it turns clockwise. The rope connected to it doesn't cross, so the cog connected to the rope will also turn clockwise. The next connection is between two cogs, so the direction will reverse counterclockwise. Keep moving through the chain of cogs, pulleys, and ropes in this manner.
 * Super Hint: The final cog will move clockwise. So will the bucket go up or down?

Puzzle 104

 * Name: Many to Cross...
 * Trigger: Talk to Dominica
 * Location: Pike Lane
 * Chapter: 9
 * Picarats: 50

Description: A wanted to return a book to her friend B, but she couldn't remember where B lives. After walking around and crossing every bridge just once, she finally arrived at her friend's house. Circle the number of B's house, then touch Submit.


 * Hint 1: There seem to be many routes that A could take to get to B's house. Let's consider a single route. First, she started by walking past house number 4 and then number 3. At that point, she still had no idea how long her route would end up being.
 * Hint 2: After numbers 4 and 3, she would then visit 2, 1, 5, and 2 again. However, she still had not found her friend's house.
 * Hint 3: After arriving at number 2 the second time, she visited 6, 3, A, 6, 8, 9, 8, and then 7. Even so, she could still not be sure which was the correct house. Had she overlooked something?
 * Super Hint: She had to cross every bridge to be sure. After arriving at number 7, she went to 8, 6, and 5 again. After crossing the last remaining bridge, she finally got to B's house. What a walk!
