Puzzle 001

 * Name: Party Crasher (US) / A Party Crasher (UK)
 * Trigger: Talk to Smith
 * Location: Exhibition Area
 * Chapter: Prologue
 * Picarats: 10

Description: There's an uninvited guest at the event, but the guard has received a few clues as to his whereabouts. "His table is next to one with a red flower. His tablecloth is a different color than any next to it. Oh, and his table isn't decorated with a yellow flower." "Next to" means tables connected by dotted lines. Take the guard to the intruder's tables.


 * Hint 1: The clues mention the colors of the flowers and the tablecloths. Use the Memo function to mark the clues on the seating plan. It may help you visualize the situation more clearly.
 * Hint 2: Though one of the clues is that "his table is next to one with a red flower", it doesn't mean that the table in question doesn't have a red flower as well.
 * Hint 3: Pay attention to the tablecloths. If you find some tables that are a different color from their neighbors...
 * Super Hint: Look for a table with a red flower and a red tablecloth. There's only one table that fits the bill.

Puzzle 002

 * Name: The Clock Shop
 * Trigger: Automatic
 * Location: Midland Bus Stop
 * Chapter: Prologue
 * Picarats: 15

Description: Below is the map to the clock shop that accompanied the letter from future Luke. Using the times on the side of the map as clues, find the shop. Draw a circle around the letter of the correct building and then tap Submit.


 * Hint 1: To figure out the route, you need to know where to turn and in which direction to go, right?
 * Hint 2: Picture the times listed on an analog clock. The minute hand is always pointed straight up, but the hour hand points in various directions...
 * Hint 3: People who are having trouble might be thinking only about the direction in which to go. Try facing the map as you might look at a clock on a wall. Then use the Memo function to draw the direction of the hour hand directly on the map.
 * Super Hint: For each time listed, move in the direction the hour hand would point on an analog clock. At the first intersection you come to, the time is 12:00, so you have to keep going north. The next time is 3:00, so you've got to head east at the second intersection you come to. You can work out the rest from here.

Puzzle 003

 * Name: Bus Scheduling
 * Trigger: Talk to Vito
 * Location: Midland Road
 * Chapter: Prologue
 * Picarats: 10

Description: It takes you one hour to get to the office by bus. Your work takes two hours to complete, after which you catch the bus back home. Based on the departure times listed below, which bus, A, B, C, D, or E, should you take to work in order to minimize the wait for a ride home? Note: The departure times for the buses home are listed to the right.


 * Hint 1: It doesn't matter what time you get to work, so you can take any of the buses and be fine. But once you get there, you're stuck taking whatever bus leaves the soonest after you finish working. Start your thinking from there.
 * Hint 2: For example, suppose there was a bus you could take to the office at 12:30 p.m. In this case, you would arrive at 1:30 p.m. It takes two hours to finish your work, so by the time you were done, it would be 3:30 p.m. That's the soonest you could catch a bus home. So for each of the buses going to the office, figure out what time you'd be done working and ready for a ride home.
 * Hint 3: You're not overlooking any choices because they seem too late, are you? As long as you get your work done, you can show up at the office at whatever time works best for you.
 * Super Hint: Go to work late, head home first thing in the morning: this schedule is the most time effective, so which bus is it?

Puzzle 004

 * Name: Moving Day
 * Trigger: Check the staircase
 * Location: Midland Rd. (Fork)
 * Chapter: Prologue
 * Picarats: 15

Description: Two men are moving boxes from the first floor to the third. The larger man can carry two boxes at a time, and it takes him one minute to get to the third floor. The smaller man can carry only one box at a time, but it takes him just 30 seconds to make it to the third floor. For both men, the return trip to the first floor is the same as the trip up. If there were seven boxes total, how many minutes would it take the men to get all the boxes to the third floor?


 * Hint 1: You can get the answer by calculating everything out, but it's a lot easier to visualize if you use the Memo function. After one minute has passed, how many boxes have been moved? And where are the locations of the two men at that time?
 * Hint 2: After a minute is up, the larger man has carried two boxes up and the smaller man has carried one. The larger man is still upstairs though, while the little guy has made it back down to the first floor. If this is the case, what's their progress after two minutes?
 * Hint 3: At the end of two minutes, the larger fellow has made it down to the first floor again and is ready to bring up some more boxes. The little guy has brought another box upstairs, for a total of four boxes on the third floor. That means there are just three boxes left to move.
 * Super Hint: In the earlier hints, you learned that after two minutes have passed, four boxes have been brought upstairs and both men were back down on the first floor. If it takes 30 seconds for the little guy to get upstairs with one box, and the larger fellow can make it upstairs with two boxes in a minute...

Puzzle 005

 * Name: The Timepiece
 * Trigger: Check the door of the clock shop
 * Location: Clock Shop Front
 * Chapter: Prologue
 * Picarats: 20

Description: You've arrived at the clock shop, but there doesn't seem to be a way to open the door. While you're looking for the doorknob, a voice from inside calls out, "Press the panel with the timepiece." What panel do you press? Remember, you can press only one.


 * Hint 1: Look for a panel with a "timepiece." However, keep in mind that there are many different kinds of timepieces. Since the instructions tell you to "press the panel with the timepiece," you know that the entire timepiece should fit on one panel...
 * Hint 2: You're not looking for an ordinary analog or digital clock. There are other types of timepieces besides those with a lot of moving parts. Try to think of some examples.
 * Hint 3: Even though you're looking for a timepiece, that doesn't mean it will necessarily help you tell the time. Instead, the timepiece you're looking for shows you how much time has passed. These days, you'd probably just use a stopwatch to do the same thing, but what you're looking for is more of a classic type of timepiece.
 * Super Hint: You're looking for an hourglass. You probably saw it without even realizing it was there. Go ahead and try to find it now.

Puzzle 006

 * Name: Needling Needles (US) / Eye on the Needles (UK)
 * Trigger: Enter the clock shop/talk to Spring
 * Location: Back Room
 * Chapter: Prologue
 * Picarats: 15

Description: "It's so dark in the shop that I'm having trouble seeing these tiny needles and thread. Can you help me out of this jam, dearie?" There are two threads, A and B. How many needles' eyes does thread A pass through?


 * Hint 1: The secret to solving this one is just patience and careful counting. This is more a piece of advice than a hint, but try using the Memo function to mark the needles that thread A passes through. It'll make things much easier.
 * Hint 2: Use the Memo function to trace the path of thread A. Then with a different color, mark the needles that thread A passes through. You can even draw a thicker line so that it's easier to see.
 * Hint 3: You still haven't got it? Well, let's just say it's a double-digit number.
 * Super Hint: The answer is the sum of the numbers one through four.

Puzzle 007

 * Name: What's the Time?
 * Trigger: Check the giant clock
 * Location: Back Room
 * Chapter: Prologue
 * Picarats: 15

Description: This analog clock fell off the wall and hit the floor so hard that all of the numbers popped off! What a mess... The clock also stopped working when it hit the ground, but even without the numbers, you can still tell exactly what time it fell. What time is the clock showing? Don't worry about a.m. and p.m.


 * Hint 1: Pay close attention to where the hour hands and minute hands are pointing. If you have an analog clock handy, you could figure out the answer by playing around with it. But if you just think about how the hands move as the time changes, you should be able to figure it out.
 * Hint 2: Have you noticed exactly where the hour hands and minute hands are pointing? What time is it on an analog clock when the hour and minute hands are in a straight line?
 * Hint 3: The hour and minute hands are each pointing straight at one of the hour marks around the clock, so the time must be right on an hour. The hour and minute hands are also in a straight line, so what time must it be?
 * Super Hint: Even if you don't own an analog clock, you can get the answer right away if you visualize the clock hands moving around as the hours go by. First, picture the hour and minute hands pointing straight up and overlapping at 12:00. Now, as the hands move hour by hour, when is the one time when they end up pointing in a straight line.

Puzzle 008

 * Name: The Odd Clock
 * Trigger: Check the bottom right clock
 * Location: Clock Shop
 * Chapter: Prologue
 * Picarats: 15

Description: Here is a numberless clock that some prankster has rotated an unknown amount. The clock is still running normally, though, and each colored circle on its face represents an hour. Even without the numbers, you can still tell what time it is. Write down the exact hour. It doesn't matter whether it's a.m. or p.m., but your answer should be in the form of XX o'clock.


 * Hint 1: The hour hand and the minute hand are overlapping each other, aren't they?
 * Hint 2: The hour and minute hands are overlapping, and they're also pointing at one of the hours.
 * Hint 3: The hour and minute hands are overlapping, and they're also pointing at one of the hours. There's only one hour that it could be.
 * Super Hint: Imagine the two hands pointing straight up. That should give you the answer.

Puzzle 009

 * Name: Cogged Down
 * Trigger: Automatic/Talk to Cogg
 * Location: Back Room
 * Chapter: Prologue
 * Picarats: 25

Description: Your task is to make the top and bottom cogs turn clockwise, as shown by the red arrows in the diagram. In order to do this, which extra cog should be inserted, A, B, or C? Tap the letter in the center of the correct cog to submit your answer.


 * Hint 1: To find out how to make both the top and bottom cogs turn in the direction indicated by their respective arrows, try following the cogs from one end to the other, checking each one's direction. You realize that two adjacent cogs always turn in opposite directions, don't you?
 * Hint 2: You can find the answer by thinking out the direction of rotation for A, B, and C. But there's an easier way to find the answer. Try reading Hint One again.
 * Hint 3: As you know, neighboring cogs move in opposite directions. If three cogs were lined up, the second cog would move in the opposite direction from the first, but the third cog would move in the same direction as the first. Thinking along those lines, if there's an odd number of cogs between two others, those two cogs will move in the same direction. If the number of cogs between two others is even, those two cogs will move in different directions.
 * Super Hint: If you insert cog A, there will be four cogs between the top and bottom cogs. If you insert B, there will be five cogs between the two main cogs. Finally, inserting C would yield four cogs between the two main cogs, which is the same value as cog A.

Puzzle 010

 * Name: What Day Is It? 1 (US) / Day Dreaming (UK)
 * Trigger: Talk to Alfie
 * Location: Anita's Place
 * Chapter: 1
 * Picarats: 15

Description: Even though we're constantly passing through time, sometimes it can be difficult to think about the way time flows. If yesterday's day after tomorrow is Sunday, what day is tomorrow's day before yesterday? Tap your answer, then tap Submit.


 * Hint 1: Try using the Memo function to chart it out. It's a lot easier to think about if you use a visual reference.
 * Hint 2: Yesterday's day after tomorrow is Sunday, so what day is yesterday? Friday!
 * Hint 3: Tomorrow's day before yesterday is...? Yesterday! See how that works?
 * Super Hint: Hints Two and Three almost give the answer away. Since yesterday's day after tomorrow is Sunday, yesterday is Friday. Tomorrow's day before yesterday is yesterday. Do you remember what day yesterday is? You should be able to figure out the answer just fine now.

Puzzle 011

 * Name: The Professor's Hat
 * Trigger: Talk to Shipley
 * Location: Midland Bus Stop
 * Chapter: 1
 * Picarats: 30

Description: Below are five blocks. Can you fit them into the shape of Professor Layton's top hat without overlapping the pieces or leaving any spaces empty? You can rotate or flip the blocks.


 * Hint 1: These hints will give you a method of completing the puzzle by flipping as few pieces as possible. Following this method, the only piece that should be flipped is [[File:PLUF_Puzzle_011_Symbol1.png]]. Of course, you could solve the puzzle without flipping [[File:PLUF_Puzzle_011_Symbol1.png]], but to do that, you'll need to flip everything else instead.
 * Hint 2: If you flip [[File:PLUF_Puzzle_011_Symbol1.png]], don't flip or rotate [[File:PLUF_Puzzle_011_Symbol2.png]]. Just place it in the top-left corner as is.
 * Hint 3: Flip [[File:PLUF_Puzzle_011_Symbol1.png]], then rotate it so the long side is laying flat. Then slide it into the bottom-left corner to form part of the hat's brim. Now rotate [[File:PLUF_Puzzle_011_Symbol3.png]] 90 degrees clockwise. Slide it nest to [[File:PLUF_Puzzle_011_Symbol1.png]] to form the rest of the brim.
 * Super Hint: If you've followed all of the hints, the only pieces left to place are [[File:PLUF_Puzzle_011_Symbol4.png]] and [[File:PLUF_Puzzle_011_Symbol5.png]]. If you rotate [[File:PLUF_Puzzle_011_Symbol5.png]] 180 degrees...

Puzzle 012

 * Name: Follow the Arrows
 * Trigger: Talk to Family Goon
 * Location: Southern Street
 * Chapter: 1
 * Picarats: 30

Description: This puzzle is super easy. All you have to do is place each of the seven cards (1, 2, 3, 4, 5, +, and =) into the square that its arrow is point to. Oh, and one more thing, the equation created bythe cards has to be valid.


 * Hint 1: First, put each of the cards into the square that its arrow is pointing to. Make sure to get the order correct.
 * Hint 2: Did you put each card where its arrow is pointing? If you did, you probably noticed that the equation is invalid. What's going on here? Well, if you make a slight change to one of the cards, the equation will work just fine.
 * Hint 3: One of the cards that looks like a number can be changed into something else. You noticed that the cards can be rotated, didn't you?
 * Super Hint: To get the equation to equal 5, change one of the cards from a number to a mathematical symbol by rotating it.

Puzzle 013

 * Name: Pick the Pen
 * Trigger: Talk to Margaret
 * Location: Hotel Lobby
 * Chapter: 1
 * Picarats: 30

Description: Only one of the four pens shown below actually works. Here are some clues to help you identify it:


 * All four pens currently have the wrong-colored caps.
 * When assembled correctly, all four pens have one white section.
 * The working pen is to the left of the one that should have the green cap.

Choose the working pen, A, B, C, or D.


 * Hint 1: For starters, remember that "the working pen is to the left of the one that should have a green cap." There are three possible arrangements for which this condition can be true. ? Green ? ?, ? ? Green ?, or ? ? ? Green.
 * Hint 2: Next, remember that "when assembled correctly, all four pens have one white section." The only pen without a white section currently is C, so you know the white cap definitely belongs to pen C.
 * Hint 3: From Hints One and Two, you know that the correct order of caps can be either Blue, Green, White, Blue or Blue, Blue, White, Green. You can now figure out the correct order from the puzzle's first clue.
 * Super Hint: Blue, Green, White, Blue can't be the correct order of caps, because pen D would have the same color cap that it started with. This would violate the puzzle's first clue. Therefore, the correct order of caps must be Blue, Blue, White, Green. That should give you the answer!

Puzzle 014

 * Name: Find the Station
 * Trigger: Talk to Becky
 * Location: Hotel Lobby
 * Chapter: 1
 * Picarats: 20

Description: A woman is looking for a subway station, but the map she has is missing the station's location. However, the map does have one hint written on the back. "To get from the flower shop to the subway station, mimic the path that students take from school to the library." The smaller squares are buildings (the pencil icon denotes the school while the book icon denotes the library). Circle the location of the subway station.


 * Hint 1: Use the Memo function to draw the student's path to the library. That's what you want to imitate.
 * Hint 2: Think about what you tell someone when giving them directions. "Go out the door and turn left. At the first intersection, turn right." Something like that, right?
 * Hint 3: Here are the directions from the school to the library: "Exit the school and turn left. At the second intersection, turn left, then pass two intersections after that. The library will be on your right."
 * Super Hint: From the flower shop, follow these directions: "Exit the slower shop and turn left. At the second intersection, turn left, then pass two intersections after that. The subway station will be on your right." It's the same route the students take from the school to the library, just rotated 90 degrees clockwise.

Puzzle 015

 * Name: Boxes of Matches (US) / How Many Boxes? (UK)
 * Trigger: Check the lamp on the table between the beds
 * Location: Hotel Room
 * Chapter: 1
 * Picarats: 30

Description: The two people shown below are talking about how many boxes of matches there are. The person on top (A) is looking down from above, and the person below (B) is looking at them from one side. At most, how many boxes are there?


 * Hint 1: Suppose B is looking at A's top-down image from the right. From B's side view, the most boxes would be, from left to right: 2 high x 2 stacks = 4 boxes 3 high x 3 stacks = 9 boxes 1 high x 3 stacks = 3 boxes 2 high x 2 stacks = 4 boxes That's 20 boxes total. Is that the most?
 * Hint 2: Suppose B is looking at A's top-down image from the bottom. From B's side view, the most boxes would be, from left to right: 2 high x 3 stacks = 6 boxes 3 high x 1 stack = 3 boxes 1 high x 2 stacks = 2 boxes 2 high x 4 stacks = 8 boxes That's 19 boxes total. Is that the most?
 * Hint 3: Suppose B is looking at A's top-down image from the left. From B's side view, the most boxes would be, from left to right: 2 high x 2 stacks = 4 boxes 3 high x 3 stack = 9 boxes 1 high x 3 stacks = 3 boxes 2 high x 2 stacks = 4 boxes That's 20 boxes total. Is that the most?
 * Super Hint: Suppose B is looking at A's top-down image from the top. If you count them up as in the previous hints and there are more than 20, that's your answer. Now all you need to do is count!

Puzzle 016

 * Name: What Day Is It? 2 (US) / Day Dreaming 2 (UK)
 * Trigger: Talk to Family Goon
 * Location: Arcade
 * Chapter: 1
 * Picarats: 20

Description: If seven days after 70 days ago was a Sunday, seven days before 70 days from today is what day of the week? Tap your answer, and then tap Submit.


 * Hint 1: Don't get confused by the big numbers. Try to break it down into a familiar quantity. For example, if seven days after 14 days ago is Wednesday, what day is today?
 * Hint 2: Seven days after 70 days ago is the same day as nine weeks ago. If that day was a Sunday, what day is today?
 * Hint 3: Seven days before 70 days from now is the same day of the week as seven days after 70 days ago. If today is Sunday, all this puzzle is asking you is what day of the week it will be nine weeks from today. Pretty simple, eh?
 * Super Hint: If you know what day of the week it is, you'll always know what day is X weeks before or X weeks after because it will always be the same day!

Puzzle 017

 * Name: The Messy Note (US) / The Scrawled Note (UK)
 * Trigger: Talk to Paillard
 * Location: Restaurant
 * Chapter: 1
 * Picarats: 30

Description: It seems you need to enter a number to open the door. The only clue you have is a hastily written note from a woman known for her poor handwriting. So, what's the number?


 * Hint 1: It looks like RHB, you say? Nope, that's not the right track at all. Try looking at things a different way.
 * Hint 2: The answer is a number, so could these chicken scratches also be numbers? The mark on the end looks a bit like an equal sign (=), doesn't it?
 * Hint 3: In this note, there are two sets of three digits that form an equation. Take a good look!
 * Super Hint: "121 - 113 =" is what's written on the paper. If you can find the answer to that, you have the answer to the puzzle.

Puzzle 018

 * Name: Slippery Trip 1 (US) / Slippery Trip (UK)
 * Trigger: Check the banana peel
 * Location: Arcade East Exit
 * Chapter: 1
 * Picarats: 30

Description: Make your way from the start to the goal, but be wary of banana peels. Whenever you step on one, you'll slide without stopping until you hit a wall! Can you find a way through these slippery streets? Tap the red arrows to move.


 * Hint 1: Try out all the different paths. Just to let you know, you have to walk for a while to reach the end.
 * Hint 2: At the first intersection, head downward. You'll immediately slide all the way to the bottom wall.
 * Hint 3: After Hint Two, walk back up to right below the peel you just slid on and hang a left.
 * Super Hint: After Hint Three, slide on the peel below you. Once you hit the bottom wall again, you can walk all the way to the goal. And be careful not to slip on any more peels along the way. If you do, it might be better to just start again.

Puzzle 019

 * Name: Checkerboard Bridge (US) / Chequerboard Bridge (UK)
 * Trigger: Talk to Berta
 * Location: Flatstone St. 2
 * Chapter: 2
 * Picarats: 35

Description: The bridge below has been painted in a black-and-white checkerboard pattern. Starting at the bottom-left arrow, you need to cross the bridge and finish at the upper-right arrow. You can move one square at a time, either up, down, left, or right. You can't move diagonally. Now here's the tricky part: how many different routes across are there that touch exactly four black squares and three white squares?


 * Hint 1: Your task is finding all the routes that meet the conditions. Touching four black squares and three white ones means you have to cross the bridge in seven moves, so you can't afford to backtrack.
 * Hint 2: Once you've figured out the type of routes that will work, just go ahead and count them up one by one. As Hint One mentioned, backtracking won't work. If you keep the other conditions in mind, you should be fine.
 * Hint 3: One route is to go straight all the way to the top row and turn right. Another is to go straight to the second row from the top, turn right, and then turn left again at the right column. These are just two of several different possibilities. Count each one!
 * Super Hint: There are more than 10 routes, but less than 20. Keep on counting! Or...start guessing!

Puzzle 020

 * Name: Making the Rounds
 * Trigger: Talk to Natalia
 * Location: Reception
 * Chapter: 1
 * Picarats: 30

Description: A doctor needs to visit nine different hospital rooms. After studying the room numbers, she notices that she can visit all the rooms in one round. In order to do so, she must go into a room that has at least one shared digit with the room she's currently in. With this method, which room will she visit fifth? Circle the correct number.


 * Hint 1: Try listing all the numbers used in all of the room numbers (there are 18 in total). How often can each digit be used?
 * Hint 2: There are some digits that can only be used once. This means that if you're in a room with a number that contains one of these digits, the only room numbers you can proceed to are those that contain the other digit.
 * Hint 3: Of the nine digits used in the room numbers, the two that can only be used once in the doctor's unique round two and seven. The rooms that contain these digits are 29 and 71. So the doctor must visit one of these rooms first and the other one last.
 * Super Hint: If the doctor starts from room 29, the order of her round will go 29, 49, 54... If she starts from 71, the order will be 71, 18, 38... Since rooms 29 and 71 have to come at either the start or the finish of her round, the fifth room visited will always be the same. So...which room is it?
