Puzzle 126

 * Name: Ten-Step Solution
 * Trigger: Check the generator
 * Location: Generator
 * Chapter: 13
 * Picarats: 50

Description: To crack this security lock, you'll need to swap blocks A and B in 10 moves or fewer. You can move any piece anywhere in any direction as long as it will fit. Now, get started!


 * Hint 1: It wouldn't be a tough puzzle if all you had to do was simply swap them. First just try moving things around, then when you can't move any more, think about how many more steps would have been required.
 * Hint 2: You'll definitely run out of moves if you keep switching between moving A and B. At some point, you're going to need to swap A and B in one fell swoop.
 * Hint 3: It doesn't matter if you start with A or B, but here's the instructions for A: slide the second block from the top over to the left, and move A down to the right of the third block. Then move the second block all the way to the right, and slide the third block up and to the left of it. The rest is up to you!
 * Super Hint: Continuing on from Hint Three, move B to the left side of the row that A is in. You can now move A into its target slot. All that's left is to use the last four moves to get B into its target slot. You can do it!

Puzzle 127

 * Name: A Real Heart Swapper
 * Trigger: Check the prime minister
 * Location: Generator
 * Chapter: 13
 * Picarats: 70

Description: There are two long wires connecting a monitoring device to the prime minister's heart sensor! Can you swap the wires connected to the pocket watch with the wires connected to the monitoring device in a single move? Swap only two blocks to connect the wires from the monitoring device at the top of the screen below to the pocket watch at the bottom right. Give it your best shot!


 * Hint 1: You need to move a pair of blocks in one single swap. First, take a look at how all of the wires are connected. Find the wires connecting the monitoring device (upper right) to the prime minister's heart sensor (lower left).
 * Hint 2: Take note that the two wires leading from the pocket watch in the lower-right corner connect it in the middle. Pay close attention to this path.
 * Hint 3: Have you noticed that only certain blocks can be swapped with each other and still connect? Keep an eye out for blocks that have matching wire entry and exit points.
 * Super Hint: The two blocks are both in the third row. Look carefully.

Puzzle 128

 * Name: Reverse Rotation
 * Trigger: Check the generator
 * Location: Generator
 * Chapter: Epilogue
 * Picarats: 80

Description: A system of gears is shown below. Gear A turns in the direction of its red arrow, which currently causes gear B to turn in the direction of its red arrow. One group of gears connecting gears A and B is labeled A. This group can be moved and rotated with your stylus, along with groups b and c below it. Utilize these groups to alter the system so that gear B turns in the direction of its green arrow. You don't necessarily need to use all of the groups, however.


 * Hint 1: The gears can't function properly if they're overlapping, so don't both trying to stack any of them.
 * Hint 2: If you link an odd number of gears between two main gears, the two main gears will rotate in the same direction. Conversely, an even number of gears linked between two main gears will cause the two main gears to rotate in the opposite direction. There are a lot of gears to count in this puzzle, but try adding them up!
 * Hint 3: You don't need to use gear group a. Try working groups b and c into the system.
 * Super Hint: Place gear group c into group a's original slot. Then rotate group b 180 degrees, and place it...somewhere.

Puzzle 129

 * Name: Block Blockade
 * Trigger: Automatic
 * Location: Fortress Door
 * Chapter: Epilogue
 * Picarats: 70

Description: Your escape route is blocked...by blocks! Luckily, you have five bombs at your disposal. Each bomb will completely destroy the block it's placed on. Remaining blocks will fall into empty spaces created below them by destroyed blocks, but they won't change shape. Place your five bombs on the five blocks that, when destroyed, will leave behind a flat surface you can drive across. Then push that button!


 * Hint 1: There are five specific blocks you need to destroy. Don't worry about making a mistake, though. You can try again as many times as you want, so just have fun blowing stuff up! You're bound to figure it out eventually.
 * Hint 2: If you look closely, you'll notice that the blocks are made up of evenly sized squares. Also, the pit is five squares deep. Start your thinking from here.
 * Hint 3: There are three blocks on the bottom row. You need to destroy the one on the left and the one on the right. Leave the middle block intact.
 * Super Hint: Do not destroy the square block in the upper right of the stack.

Puzzle 130

 * Name: The Final Puzzle
 * Trigger: Automatic
 * Location: Layton's Office
 * Chapter: Epilogue
 * Picarats: 30

Description: "Look! I made myself a wax stamp! It's like the one you use to seal your important envelopes and documents, except it looks like my hat and the L stands for Luke! I've already used it once. See? Isn't the blue wax neat? It matches my hat! Anyway, here's my puzzle: of the four examples, A, B, C, and D, which one is my actual stamp? Circle your answer."


 * Hint 1: Keep in mind that a stamp will print a mirror image of its actual design.
 * Hint 2: The stamps are all circular, so pay close attention to what's inside: the outline of a hat and an L. First off, take a look at the direction the L is facing...
 * Hint 3: Stamp B is the only one that doesn't have the L correctly reversed, so you can eliminate that option. Now look closely at the hat shape of stamps A, C, and D.
 * Super Hint: The top part of the hat shape in stamp A is touching the outer circle, so you can safely eliminate that option. It's just between stamps C and D now!
