Puzzle 076

 * Name: Top of the Tower
 * Trigger: Talk to Geoff
 * Location: Watchtower 2nd Floor
 * Chapter: 4
 * Picarats: 20

Description: In a quiet town, there's a tower that commands a view of the whole town. Since you can see the whole town from the tower, logic dictates you should be able to see the top of the tower from anywhere in town. However, there's one place in town shown on the map below from which you have clearly no chance of seeing the top of the tower. Find and circle this place.


 * Hint 1: Looking for a place that has its view obscured by another building? Hmm, it doesn't look like there are any places around the town like that.
 * Hint 2: You need to find a place where the tower's top can't be seen. To put it another way, you're looking for a place that doesn't allow you to see the outside of the tower.
 * Hint 3: There's one indoor location from which you definitely won't be able to see the outside of the tower.

Puzzle 077

 * Name: Balancing Ornaments
 * Trigger: Talk to Pavel
 * Location: Mine Machine Room
 * Chapter: 6
 * Picarats: 30

Description: Small ornaments dangle from a metal bar, and they've thrown the bar off balance. The five ornament strings are spaced equally apart, and each of the three types of ornaments weighs a different amount. The heaviest ornament weighs the same as three of the lightest ones, while a medium ornament weighs the same as two of the lightest ornaments. Place one of the three ornaments in the rectangle in the space marked with a question mark to restore the bar's balance.


 * Hint 1: The center strand of ornaments won't affect the balance of the bar, so ignore it. Also, the two strands hanging the farthest out on the bar are the same weight, so try comparing the ornaments on the far left to the ornaments on the far right. You might find out something new.
 * Hint 2: Look at the strands on the far left and the far right. While they both contain sun and moon ornaments, only the far right strand has a star. By comparing the ornaments on these two strands, you can probably figure out how many suns and moons it takes to equal the weight of a star.
 * Hint 3: A single star weighs the same as one sun and one moon together. Now that the weight of one star is clear, you should be able to compare the two strands next to the center strand.

Puzzle 078

 * Name: A Maze of Doors
 * Trigger: Inspect the framed grid
 * Location: Mine Room
 * Chapter: 6
 * Picarats: 25

Description: All the doors in the maze below only open in one direction. Each door can be opened by pushing from the direction shown below, but when approached from the opposite direction, no amount of pulling or pushing will open it. If you tried to go through the whole maze from the start and passed through every room, you'd never make it to the exit. However, this feat would be possible if one of the doors could open in the opposite direction. Can you find and circle this door?


 * Hint 1: Let's review this puzzle's conditions. You need to make one door open in the opposite direction, and you must pass through every room on your way to the exit. But no one ever said you can only pass through each room once.
 * Hint 2: Starting from the IN sign, you'll soon bump into a door that should open the opposite way. So to proceed, one of the first door you meet will have to open in the opposite direction. The upper door in the first room and the two doors in the room to the immediate right of the first room open in a direction that keeps you from passing through. One of these three doors is the door you'll need to change.
 * Hint 3: The upper door in the first room is fine the way it is.

Puzzle 079

 * Name: The Gear Switch
 * Trigger: Check the door
 * Location: Mine Machine Room
 * Chapter: 6
 * Picarats: 20

Description: The button that opens the door in front of you is buried deep within this machine, so you can't push it directly. However, by pulling the knob at the top to the left or right, you can move the various gears and plates in the machine, allowing you to press the button at the bottom. In order to hit the OPEN button, should you pull the knob toward A or B?


 * Hint 1: When one gear rotates with another, the two gears must rotate in opposite directions. Use the Memo function to keep track of the direction of each gear's rotation.
 * Hint 2: The gear at the bottom has to rotate clockwise to hit the switch, so the board of teeth directly above it will need to move to the right. Make sense? Now continue that line of thought as you move up toward the knob.
 * Hint 3: The board of teeth underneath the three gears at the top needs to move to the left. Therefore, the gear directly above it needs to rotate clockwise. Keep going until you reach the knob at the top!

Puzzle 080

 * Name: The Elevator Switch / The Puzzling Lift
 * Trigger: Attempt to use the elevator
 * Location: Mine Lift
 * Chapter: 6
 * Picarats: 40

Description: The circuit board for the elevator contains a puzzle. According to the instructions, you need to make the blue and red balls switch places in order to restore power to the elevator. Are you up to the task?


 * Hint 1: There are several ways to go about solving this puzzle. One surefire technique is to work with the L-shaped blocks. You can free up some extra room by moving these blocks so that they fit together neatly with neighbouring blocks.
 * Hint 2: In order to get both of those balls to swap places, you first need to move one ball out of its hole and park it somewhere while you move the other one. To do so, clear up some space by gathering all those L-shaped blocks in either the left or right side of the box.
 * Hint 3: If the method from Hint Two isn't working, here's another technique to try. Create space by slotting L-shaped blocks together to create pairs. In order to do this, move the L-shaped blocks to the opposite edges of the box, then combine them.
