Caution! This page contains all the hints and solutions for every puzzle from 1 to 25. Scroll carefully or you might spoil the answer of a puzzle for yourself. The solutions are hidden behind spoiler tags, so only take a peek if you're desperate.

Puzzle 001

 * Name: Dr. Schrader's Map
 * Trigger: Automatic
 * Location: Outside Layton's office
 * Chapter: Prologue
 * Picarats: 10

Description: In the map to Dr. Schrader's home, several pieces in the center have been cut out. Restore the map by inserting the missing pieces in the correct spots. Touch a piece with your stylus to grab it, then slide your stylus to move the selected piece across the screen. You can't rotate the pieces. It may sound simple, but don't forget that you can move or remove pieces, including the one already in the middle of the map.


 * Hint 1: Including the one piece that's in the middle of the map from the start, you have six pieces to move around. ...And only five spaces to put them in. That means one of those pieces won't be used in the solution.
 * Hint 2: Take a close look at each individual piece of the map, as well as the set portion of the map. As long as you can make the roads on each piece fit cleanly into the larger framework, you'll find the answer sooner of later.
 * Hint 3: You may have already noticed, but the piece positioned in the center of the map at the start of the puzzle isn't used in the solution.

Puzzle 002

 * Name: The Doctor's Home
 * Trigger: Automatic
 * Location: In the Laytonmobile
 * Chapter: Prologue
 * Picarats: 15

Description: Find Dr. Schrader's window from the details in his letter. "In the morning, I often awaken to the sound of music drifting in from a nearby flat. Looking out, I spy a flag fluttering gently outside my window, take a single sip of my tea, and turn my attention to the morning sun. Not many flats in London have a view of the sunrise anymore, you know." Circle the window from which the doctor views the sunrise.


 * Hint 1: Since the doctor mentions hearing music from a nearby flat, you can rule out the window the music is coming from.
 * Hint 2: As the doctor makes special mention of being able to see the sunrise, it's likely his apartment is one of the ones higher up in the picture.
 * Hint 3: The Doctor talks about seeing the flag outside his window move in the breeze from his seat inside. There appears to be only one flat in the bunch where you could accomplish this feat.

Puzzle 003

 * Name: The Right Key/Which Key?
 * Trigger: The door.
 * Location: Outside Schrader's Office
 * Chapter: Prologue
 * Picarats: 20

Description: Which key opens the door? As you might expect, the key won't open the door if its shape won't let it pass through the keyhole. Use your stylus to fit keys to the lock. Examine each key carefully and use the stylus to move the keys and find the one that fits into the lock.


 * Hint 1: At a glance, the ends of the keys look too intricate when compared with the simple shape of the keyhole. Concentrate on finding a key with a shape that matches the structure of the lock.
 * Hint 2: Who's to say one end of a key is any better than the other?
 * Hint 3: Turn each key around and try inserting the part you'd normally call the grip.

Puzzle 004

 * Name: "Where's the Town?"
 * Trigger: Automatic
 * Location: Dr. Schrader's Office
 * Chapter: Prologue
 * Picarats: 30

Description: With its windows opening out into thin air eight stories up and its door securely bolted, you might think that this room is inaccessible from the outside. However, a single unusual detail reveals the truth of what went on here. Your job is to look around the room by tapping the arrows and find this detail. Once you've got it, circle the area with your stylus and choose Submit to give your answer. Make sure to circle only one object when you answer.


 * Hint 1: Take a good look at all the views. You're looking for something unusual. There are lots of odd objects in the room, but while many may be strange, they aren't the brand of unusual you're searching for.
 * Hint 2: You won't find the answer in the areas that Professor Layton and Inspector Chelmey are examining.
 * Hint 3: The object in question is often found in pairs.

Puzzle 005

 * Name: "Where's the Town?"
 * Trigger: Open trunk
 * Location: Layton's Cabin
 * Chapter: 1
 * Picarats: 30

Description: Luke's belongings are all over the place and need to be packed away in his trunk. Use your stylus to move individual objects into the trunk, and make sure that none of them overlap. When you think everything has been placed neatly into the trunk, tap Submit.


 * Hint 1: You can use little items like the harmonica and the book to fill in small gaps later, so pack up the big items first.
 * Hint 2: That unwieldy frying pan and spatula set go in the lower-left corner. Luke's teddy bear belongs in the upper-right corner.
 * Hint 3: Luke's book should be placed in the upper-left portion of the trunk. By this point, you should be most of the way toward solving the puzzle, so try working the rest out on your own.

Puzzle 006

 * Name: Pancake Stacks 1/Piles of Pancakes 1
 * Trigger: Sally
 * Location: Car 06
 * Chapter: 1
 * Picarats: 15

Description: Now here's a tasty puzzle for you. Your task is to take that big stack of pancakes on the left plate and move them to the plate on the far right. In doing so, however, you need to follow these rules:
 * You can move only one pancake at a time.
 * A pancake can never rest on another pancake smaller than itself.

Feel free to shift things around as much as you like and to use the middle plate in completing the puzzle.


 * Hint 1: This puzzle isn't a brain buster, so take a step back for a moment. One way to solve puzzles like these is just to experiment by moving the pancakes around.
 * Hint 2: If you can get the biggest pancake over to the red plate, you're within inches of solving the puzzle.
 * Hint 3: Shift the smallest pancake to the red plate, then place the medium-sized pancake on the middle plate. Next, place the smallest pancake on top of the medium pancake. This will free up the red plate for the biggest pancake.

Puzzle 007

 * Name: Dining Couple/Four Couples
 * Trigger: Chester
 * Location: Car 05
 * Chapter: 1
 * Picarats: 20

Description: Four couples sit elbow-to-elbow in a crowded dining car. All diners are sitting next to or across from their partners. Using the information above, can you determine where Mrs. Hadley is sitting? Circle her and touch Submit.
 * The Joneses are sitting by the aisle.
 * The mustachioed Mr. O'Connor sits beside his wife.
 * Mr. Lambert sits across from his wife.


 * Hint 1: The mustachioed Mr. O'Connor is b. Seeing how c and f are man, his wife has to be a.
 * Hint 2: The Joneses are both sitting by the aisle, which means they must be sitting across from each other. Since you know b is Mr. O'Connor, c and g must be Mr. and Mrs. Jones, right?
 * Hint 3: So where is Mr. Lambert in all this? We now know a and b to be the O'Connors, so the people sitting across from them must also be a couple. But they can't be the Lamberts because the Lamberts have to be sitting across from each other... Keep the above in mind, and you should have everything you need to identify all four of the couples.

Puzzle 008

 * Name: Luke's Big Dinner
 * Trigger: Chester
 * Location: Car 05
 * Chapter: 1
 * Picarats: 25

Description: "Now, Luke, are you sure you can really eat all of that? You put in quite an order there." "No sweat, Professor! I'll clean my plate and still have room for more!" It's no wonder the professor is concerned, as Luke's order cost twice what the professor's did. Below you can see all the items Luke and Professor Layton ordered, as well as the price of each item. Touch the price for each of the items that are part of Luke's order.


 * Hint 1: Start by adding up the cost of the entire meal.
 * Hint 2: Luke's meal cost twice as much as the Professor's. That means the ratio of Luke's cost compared to the professor's cost must be 2:1.
 * Hint 3: The cost of the entire meal comes out to 105 pounds. This total needs to be split to fit our ratio of 2:1. Therefore, Luke's meal cost 70 pounds and the professor's cost 35. What combination of food and drink items can you find that add up to 70?

Puzzle 009

 * Name: Stacked Glasses
 * Trigger: Champagne Glass
 * Location: Car 05
 * Chapter: 1
 * Picarats: 10

Description: The owner of a four-star restaurant assigns a young waiter the task of stacking glasses in a decorative way. Eager to please, the young waiter immediately draws five seperate designs and shows them to the owner. The owner takes one glance at the designs and, with a look of irritation, turns to the boy and cries, "This design is preposterous! What were you thinking?" Which of the five designs is the owner talking about?


 * Hint 1: "This design is preposterous!" The owner wasn't angry because the design in question was hard to assemble. He was upset because one design was physically-impossible to replicate in real life.
 * Hint 2: A and C could probably be pulled off with steady hands and a lot of patience.
 * Hint 3: One design, while perfectly natural when drawn out in 2D, stacks the glasses in a way that is impossible to create in reality. On paper, is cup is represented by a single bent line, but real glasses have a rim on the top and walls of a set thickness.

Puzzle 010

 * Name: A Work of Art
 * Trigger: Automatic
 * Location: Car 06
 * Chapter: 1
 * Picarats: 15

Description: The drawing below is made up of curved lines that intersect to create sections. If you want to color in the entire canvas so that no section touches the side of a section with the same color, what's the fewest number of colors you can use? You can use a color as many times as you want as long as it doesn't touch any area with the same color. Once you have your answer, tap the Input Answer icon and enter the number of colors.


 * Hint 1: There's no trick here. You might have an easier time if you mark the drawing using the memo function.
 * Hint 2: Why don't you take a closer look at the corners of the picture?
 * Hint 3: You can complete most of the picture using only two colors, but did you notice there's one pesky area down in the lower-left corner that requires an additional color?
