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!

Puzzle 105

 * Name: Bouquet Giveaway
 * Trigger: Talk to Aldus
 * Location: Café Entrance
 * Chapter: 9
 * Picarats: 30

Description: A girl received a large bunch of flowers from an admirer. She felt that she had too many, so she gave them away to people she met on her way home. Each time she started by giving just one flower, and then she decided to give half of the remaining bunch. After meeting five people, she had only one flower left. How many flowers were in the whole bunch?


 * Hint 1: In the end, she only has one flower, so when she met the fifth person, she must have been holding three flowers. Keep working backward this way, doubling and then adding one.
 * Hint 2: When she met the fourth person, she still had seven flowers.
 * Hint 3: As she ran into the third person, there were 15 flowers left in the bunch.
 * Super Hint: Continuing backward one meeting at a time, you can work out that the girl had 31 flowers just before she bumped into the second person. Therefore, the number of flowers she started with must be twice 31 plus one!

Puzzle 106

 * Name: Apple Bounce
 * Trigger: Talk to Charlie
 * Location: Great Ely Street
 * Chapter: 9
 * Picarats: 45

Description: Newton wants to drop some apples from the top of his ladder into his friend's basket. Place trampolines carefully to help Newton bounce the apples on their way. Makes sure they don't hit the ground or bounce into any walls before they reach the basket! Nobody likes a bruised apple.


 * Hint 1: Those juicy apples sure can bounce! See what happens when you change the angle of a trampoline.
 * Hint 2: It's possible to solve this puzzle using only a single trampoline. See if you can find the best place to put it.
 * Hint 3: The best place for a single trampoline is in the path of the falling apple toward the bottom of its fall. Try changing the angle of the trampoline to make the apple bounce through the gaps between walls.
 * Super Hint: With the right placement, you can bounce an apple right over the top of the leftmost wall. You'll need two trampolines to solve the puzzle that way, and the placement might be a tad tricky... but why not give it a try?

Puzzle 107

 * Name: How Many Rooms?
 * Trigger: Talk to Joseph
 * Location: Hotel Lobby
 * Chapter: 9
 * Picarats: 45

Description: The guest rooms in this hotel all have two windows each. From the second floor upward, all rooms are guest rooms and all the windows belong to a room. The ground floor has no guest rooms, but you can enjoy a fine English breakfast and a cup of Earl Grey. If all four sides of the hotel have an identical layout, how many guest rooms does the hotel have in total?


 * Hint 1: Take it one floor at a time, starting with the second floor. The number of guest rooms on a floor will equal the number of windows on the floor divided by two.
 * Hint 2: The number of windows on the sixth and seventh floors is eight per floor. How many guest rooms is that per floor?
 * Hint 3: Every floor from the second to the fifth has 16 windows in total. So how many rooms are there on each of those floors? If you've worked that out, you just need to do the math to get the total number of guest rooms in the hotel.
 * Super Hint: If your math really isn't working, try counting all the windows you can see from the second floor upward. The number of windows you can see is half of the total number, and each room has two windows. If you pot these two together, you'll realize that the number of windows you can see on these floors is the same as the total number of guest rooms.

Puzzle 108

 * Name: Pendant Penchant
 * Trigger: Talk to Bobbi
 * Location: Hotel Lobby
 * Chapter: 9
 * Picarats: 30

Description: One of the three trinkets below is said to be a magic pendant made from three types of beautiful crystals resembling crimson suns, pearl stars, and cerulean tears. This priceless treasure can be identified by the fact that if the quantity of one type of crystal were doubled, it would equal the combined quantity of the other crystals on the pendant. Which pendant is the magic one?


 * Hint 1: Try to think about how many crystals are on each pendant. You won't get far if you don't find this out first.
 * Hint 2: Which type of crystal should you double? Well, adding any number to itself always makes an even number. Even + even = even. Odd + odd = even. Keeping this in mind should make things a lot easier.
 * Hint 3: The type of crystal you should double is the crimson suns. Now you just need to do some simple math.
 * Super Hint: If you still can't find it, you must be having trouble with your sums! Find the pendant made up of six crimson suns, seven pearl stars, and five cerulean tears.

Puzzle 109

 * Name: An Orderly Bookcase
 * Trigger: Talk to Olga
 * Location: Library
 * Chapter: 9
 * Picarats: 40

Description: This bookcase houses a set of books wrapped in five different-coloured bindings: red, blue, yellow, green, and orange. Each shelf contains one book of each colour, but the colour order varies from shelf to shelf. Your challenge is to organize the books on each shelf in the same order in only three moves. Swapping the positions of two books counts as one move.


 * Hint 1: Forget about the bottom shelf, to begin with, and focus on getting the top four shelves into the same order.
 * Hint 2: You should be able to arrange the top four rows of books in the same colour order using just two moves. Now you have just one move left. Can you use it to get the bottom shelf of books in the same order?
 * Hint 3: The books on the first and third rows already have the same order, so there's no need to rearrange them. You can get this same order on the second shelf by switching the rightmost two books, and on the fourth shelf by swapping the boom that's farthest to the left with the one second from the right.
 * Super Hint: Are you struggling with the last piece of the puzzle? It doesn't matter where on each shelf the books are, as long as the colour order is the same. Take a look at the bottom shelf, and see what happens if you move the rightmost book to the far left. Just don't go swapping it with another book.

Puzzle 110

 * Name: Jumpin' Marbles
 * Trigger: Talk to Thomas
 * Location: East District
 * Chapter: 9
 * Picarats: 55

Description: The aim is to remove the silver marbles from the board except for one. You can jump a marble horizontally or vertically over an adjacent marble and into an empty space to remove the jumped-over marble from the board. Also, you can move or jump over any marble except those marked with an X.


 * Hint 1: The key is to work the other marble to the centre of the board. Start by jumping a marble from the bottom into the centre space.
 * Hint 2: After following Hint 1, move the marble at the top of the second column from the right down and then to the left. Then jump the marble in the very centre down over the marble you just moved. Next, the marble at the bottom of the second column from the left should be moved to the right.
 * Hint 3: Next, find the marble marked with an X on the top left, and jump the marble below it downward. Jump both marbles in the second row from the bottom upward, then move the marble in the centre to the right. If you jump the rightmost marble in the second row from the top downward, you're nearly there!
 * Super Hint: Move the marble that's farthest to the right into the centre. Jump over that centre marble with the one on its left. Now take the marble nearest the top and move it down. There are just two marbles left to remove!

Puzzle 111

 * Name: Empty Seats
 * Trigger: Talk to Hanna
 * Location: Triton Estate
 * Chapter: 9
 * Picarats: 35

Description: There are five couples seated at this dinner table, but all the wives are visiting the bathroom and you've lost track of who is married to whom. When you ask your friend, he tells you only the following facts: 1. No one sits opposite their spouse. 2. No one sits next to their spouse. 3. Wife A and Wife B sit on opposite sides of the table. Where is Wife C's seat? Touch a seat to place her there.


 * Hint 1: For starters, figure out where wife B is sitting. Husband B is sitting on the right-hand side of the table, so you know from the second clue that seats 4 and 5 can be ruled out. You can also rule out seat 2 in light of the first clue, which only leaves 1 and 3 as the possible seats where wife B is sitting. Which one is it?
 * Hint 2: Now try to figure out where wife A is sitting. From clues 1 and 2, you can narrow it downs to seats 2, 3, and 5. From Hint 1, you learned that wife B is sitting in either seat 1 or 3. Now take a look at clue 3. Wife A must be in seat 5, on the opposite side of the table from wife B.
 * Hint 3: Now try to figure out the location of wife D. From clues 1 and 2, you can narrow her location down to seats 3 and 5. You already figured out that wife A is in seat 5, so wife D must be in seat 3. That means wife B, whose location you narrowed down earlier to seat 1 or 3, must be sitting in seat 1.
 * Super Hint: Figure out where wife E is sitting. From clues 1 and 2, you can narrow it down to seats 1 and 4. Wife B is in seat 1, so wife E must be in seat 4. This leaves only one seat, which must be where wife C is sitting!

Puzzle 112

 * Name: Wall Repair
 * Trigger: Talk to Brock
 * Location: Wrecked Home
 * Chapter: 9
 * Picarats: 30

Description: There is a square hole in the side of this damaged building that looks as if it could fall over at any minute. Try to fill the hole using these five identically shaped blocks. As long as all the blocks are used in the wall, it's OK for there to be a few gaps. You can flip and rotate the blocks as required.


 * Hint 1: The main thing is to get all five blocks inside the hole. Start by rotating a block 180 degrees and putting it on the bottom right so that there is one square of empty space in the corner. You can use any block you want since they're all the same.
 * Hint 2: After following Hint 1, flip a block and rotate it 90 degrees clockwise. Place that block on the bottom left. There should be one square of empty space left between it and the first block.
 * Hint 3: After following Hint 2, flip another block and rotate it 180 degrees. Place it against the left wall. This should also leave one square of empty space.
 * Super Hint: Continuing from Hint 3, rotate the next block 90 degrees counter-clockwise. Place that block in the middle of the hole. Now figure out how to place the last block to finish repairing the wall.

Puzzle 113

 * Name: Crystal Carafes
 * Trigger: Talk to Marilyn
 * Location: Market South
 * Chapter: 9
 * Picarats: 30

Description: Three shopkeepers each have two crystal carafes filled with juice for sale. The juice in each carafe is identical, but the carafes come in three sizes: small, medium, and large. Whichever shopkeeper you buy from, the price is the same. Only one shopkeeper sold a large carafe. Can you tell which one?


 * Hint 1: Each vendor's two carafes are lined up in front of each other, which makes it difficult to tell what's what when looking at them straight on. If you study the three sets carefully, you should start to notice some subtle differences between them.
 * Hint 2: First, take a look at the level of juice in the carafes. In one of the sets, the level is different between the two. This should help you figure out the size of these two carafes.
 * Hint 3: The next thing you should pay attention to is the transparency of the carafes. The differences between the sets are slight, but they're discernable if you look closely. Once you've figured out how the transparencies are different, it should help you figure out the different sizes of the carafes.
 * Super Hint: Two of the vendors are selling two medium carafes, and the other is selling one small one. The vendor selling the large carafe has the small one displayed in front of it.

Puzzle 114

 * Name: Typing Numbers
 * Trigger: Talk to Crow
 * Location: Market Center
 * Chapter: 9
 * Picarats: 35

Description: This typewriter has only number keys. Pressing a single key type out that number immediately, but pressing subsequent keys takes an extra second for each key further along the keyboard from the previous key. For example, pressing 1 then 2 takes one second. Pressing 1 and then 3 takes two seconds. What is the shortest time possible (in seconds) it will take to type "68060" as shown on the paper?


 * Hint 1: Working out how long it takes to type out the number normally isn't enough. Try thinking of a quicker way to type it out.
 * Hint 2: It doesn't matter how fast you type, the speed of the typewriter will not change. The only way to make things quicker is to change the numbers you're typing...
 * Hint 3: The answer is hidden in the number "68060". Make sure you give "68060" a close look.
 * Super Hint: You're looking at this puzzle all wrong. In fact, you should be viewing it upside down. Try it out! Doesn't "68060" look like a different number now?

Puzzle 115

 * Name: Market Shortcut
 * Trigger: Talk to Nabby
 * Location: Market North
 * Chapter: 9
 * Picarats: 75

Description: There are several roads crisscrossing the marketplace. From the entrance, you want to pass over every section of the road and reach the exit without ever taking the same portion of the road twice. Draw a single straight line showing the road that would need to be constructed to make this possible. The new road can only start and end at existing intersections or corners.


 * Hint 1: Don't forget about the Memo function! You can use it to trace a route along the streets and gain a better understanding of the problem.
 * Hint 2: The road you will need to create is a single diagonal line connecting two intersections.
 * Hint 3: This is a classic single-traversal puzzle. In order to draw a route that passes through every stretch of the road exactly once, there must be an even number of roads extending from each intersection.
 * Super Hint: Search for intersections that have an odd number of roads extending from them. There should be two such points. How can you add a single line that will result in both intersections having an even number of roads?

Puzzle 116

 * Name: Stained Glass
 * Trigger: Talk to Scraps
 * Location: Market West
 * Chapter: 9
 * Picarats: 30

Description: The stained-glass window below is split into four triangular panels that combine to create a single design. Place the panels within the window frame to complete the design, then tap Submit.


 * Hint 1: The design of this window is quite intricate. If you're focusing on the centre of the window, it may be making matters more difficult than need be.
 * Hint 2: When combined correctly, some of the pieces form leaf-shaped designs. Try looking for those shapes and putting them together.
 * Hint 3: Look for the large, coloured circle on each panel. When the panels are aligned properly, the upper-right panel will contain the same-coloured circle as the lower-left panel and the upper-left panel will contain the same-coloured circle as the lower-right panel.
 * Super Hint: Have you noticed that putting certain panels together in a certain way will create a diamond shape where two edges meet? Arrange the panels so that two of these diamond shapes are created, one purple and one blue.

Puzzle 117

 * Name: A Token Puzzle
 * Trigger: Talk to Shackwell
 * Location: Black Market
 * Chapter: 9
 * Picarats: 45

Description: It's not safe to walk around an auction house with large sums of money, so this particular establishment offers tokens in exchange for cash. The heart tokens are worth 5,000, the clubs are worth 10,000, and the diamonds are worth 50,000. The total dollar amount, in thousands, of the 16 buyers at this table is summed up at the end of each row and bottom of each column. Can you figure out which token each buyer is holding?


 * Hint 1: Take a look at each row and column carefully. Is there one that has a total that could only be reached if all four buyers have the same token?
 * Hint 2: Focus you attention on column C. The total for the four tokens in column C is 20,000. The only way this number can be reached is if all four buyers have a heart token worth 5,000 each. Make each token in column C a heart and see if that helps you figure out the rest of the puzzle.
 * Hint 3: Now take a look at row 6. The total of the four tokens in this row is 35,000, and you already know which token in this row must be a heart from the previous hint. Since the heart is 5,000, the other three need to equal 35,000, which means each of the other tokens in this row must be a club!
 * Super Hint: Let's focus on diamond tokens now. There are two diamond tokens in each of the following: column D, row E, column A, and row F, and no diamond tokens anywhere else. Knowing this, the rest should be a walk in the park!

Puzzle 118

 * Name: Sketchy Stars
 * Trigger: Talk to Louis
 * Location: Grand Bridge St.
 * Chapter: 9
 * Picarats: 30

Description: Here's a sketch of seven stars on a piece of graph paper. It's quite pretty, but the stars aren't all in the correct locations at the moment. When placed in their correct locations, all seven stars will sit in different rows from the others, vertically, horizontally, and diagonally. Only the three lighter-coloured stars can be moved. Can you place them in their correct locations?


 * Hint 1: Try using the Memo function to block out the rows that are already used by the four fixed stars. Remember, you need to make sure that no two stars share a row in any direction: vertically, horizontally, or diagonally. Once you block out the rows already occupied by the fixed stars in each direction, you'll have a clearer idea about where to move the others.
 * Hint 2: There are actually two different ways to solve this puzzle. Here are some hints to lead you toward one of them: Place the first movable star in the third square from the right on the bottom row. When placing the other two stars, be sure they don't line up with any other star in any direction.
 * Hint 3: Put the second movable star into the square that's one square over from the left and three squares up from the bottom.
 * Super Hint: Put the last star in the centre square. That should do it! Once you've got them all in place, however, feel free to check and make sure no two stars are lined up in any direction.

Puzzle 119

 * Name: Window Design
 * Trigger: Talk to Dean Delmona
 * Location: Lobby
 * Chapter: 9
 * Picarats: 60

Description: A man wants to decorate his window so that people can't see into it so easily. Help him out by decorating the window with these transparent apple stickers, making sure that every part of the window is covered. The apple stickers may be oriented in any direction and can even be flipped, but you must make sure that every frame has one apple and no stickers extend past the edges of the window.


 * Hint 1: Rotate the rectangular sticker so that the clear part is on the top left, and place it in the bottom-right corner. There's no need to flip this one.
 * Hint 2: Put the L-shaped sticker with the transparent corner on the top right of the window and rotate it so that the clear part is on the bottom right. The sticker that goes in the top-left corner already has the correct orientation. Look for a sticker with apples arranged in an "L" shape that will fill the edges of this corner.
 * Hint 3: Place the sticker that has apples arranged in a T-shape in the bottom-left corner. Rotate it so that the long edge is on the left-hand side standing vertically. Next, rotate and flip the Z-shaped sticker so that it fits in below the sticker with the T-shaped apples.
 * Super Hint: The sticker with four apples in a square should be placed so that it's one row up from sitting in the centre of the window. Make sure you put it in the right place! That should be all the help you need. The rest is up to you!

Puzzle 120

 * Name: Gallon Hat
 * Trigger: Talk to Rosa
 * Location: Layton's Office
 * Chapter: 9
 * Picarats: 30

Description: Can you rearrange the puzzle pieces that make up Layton's hat into the shape of a juice bottle? You can move, flip, and rotate the pieces in any direction.


 * Hint 1: Take the small two-block piece and place it vertically along the right-handed side of the bottle's neck.
 * Hint 2: Now let's work on the bottom of the bottle. Take a piece shaped like a backward J, rotate it 90 degrees, and place it at the very bottom of the bottle.
 * Hint 3: Next, rotate the piece shaped like an "L" so that you can place it below and to the right of the label in the middle of the bottle.
 * Super Hint: If you followed the previous hints, you should be close to completing the bottle. Now flip the piece in the bottom-left corner of the hat and rotate it so that it fits the space on the bottom left of the bottle. After that, fitting in the final piece should be quite straightforward.
