Puzzle w01
- Name: From Five to Four
Description: A set of matches are arranged so they form five squares. To solve this puzzle, you need to change the number of squares from five to four by moving exactly two matches. Your four squares must be uniform in size, and you must use all of your matches when forming the squares.
- Hint 1: In the original layout, every match is needed to form the five squares, so the task of forming one less square while still using all of the matches might seem challenging. However, you can make things easier by focusing on reducing the number of matches that serve as a side for multiple squares.
Move the bottom match of the second square from the right and the top match of the left square on the upper row and form a square above the square you took the first match from.
Puzzle w02
- Name: Treasure Chests
Description: Although all six chests appear to be of equal value, in actuality, one of the chests differs from the rest. Choose the chest that has a different total value.
- Hint 1: Some chests may not have the same number of gems. How many gems do you count in a single chest?
Chest D has an extra blue gem.
Puzzle w03
- Name: How Many Nines?
Description: How many times does the number nine appear within whole numbers between one and 100?
- Hint 1: There's no trick to this one. No, really! All you need to do is count them up.
20 times.
Puzzle w04
- Name: Aliens?
Description: A famous space explorer has just discovered a new planet and landed on its surface to investigate it further. During his three-hour investigation, he counted 379 male Octopleans, 493 female Octopleans, and 125 that had the features of both male and female Octopleans. So right now, how many aliens are there on this new planet?
- Hint 1: The whole planet is covered with Octopleans, but adding their numbers up won't get you the answer you're after. Perhaps you jumped to conclusions when considering answers for this puzzle.
There is only 1 alien on the space planet, which is the space explorer.
Puzzle w05
- Name: Nose to Nose
Description: Four horses are running around a course made up of several concentric circles. Horse A runs one lap an hour on its course. Horse B runs two laps an hour on its course. Horse C runs three laps an hour on its course. Horse D runs four laps an hour on its course. All four horses line up at the bottom of the circle and start running their courses at the same time. How many minutes will it take until all four horses are lined up nose to nose on a straight line again?
- Hint 1: It won't take even an hour for the horses to line up nose to nose once more. All the horses' noses have to be lined up along the same straight line, but nowhere does it say that the horses must face the same direction.
30 minutes. The four horses will be lined up nose to nose, though two horses will be facing the opposite direction on the other end of the track.
Puzzle w06
- Name: Cut the Cake
Description: When viewed from above, the slice of cake below is an equilateral triangle. Your goal is to produce four sides of a cube by making one cut into the cake. Connect two dots to cut the cake. You should know that this particular cake has a thickness equal to one-quarter the length of the cake slice.
- Hint 1: You can only produce two new surfaces by cutting the cake. Where do you need to cut the cake in order to make these cross sections appear square? When you figure that out, you've basically got the answer. Recall what the puzzle said about the thickness of the cake.
Cut out the smallest triangle from any of the corners.
Puzzle w07
- Name: Soccer Ball
Description: The surface of your standard soccer ball is made up of several black pentagons and white hexagons, just like the ball pictured below. If the ball shown here has 12 black pentagons, how many white hexagons does the ball have?
- Hint 1: Here are some helpful facts to keep in mind. No pentagon shares a side with another pentagon. Also, there are a total of 12 pentagons on the ball. Since every pentagon has five sides, there are a total of 60 sides. All hexagons share three sides with other hexagons.
There are 20 white hexagons.
Puzzle w08 (US Version)
- Name: What's Hidden?
Description: You've stumbled across a strange painting. It appears to depict a frog sitting out in the rain, but there's more to this picture than meets the eye. What other living creature is hiding within this picture? Your answer must be five letters long.
- Hint 1: This puzzle is all about looking at the picture from a fresh perspective. Try rotating your DS to the side and see what happens.
The frog is also a Horse head.
Puzzle w08 (EU Version)
- Name: Around the Towns
Description: A salesman is planning his route around 16 towns using this map. Starting from S, he wants to visit every town and end up back at S. Assuming he has decided to go to town 1 first, and that he will only visit each town once to save on fuel, what number will the town marked with a star be in the sequence? By the way, roads marked with X are closed.
- Hint 1: There is only one route on the map that will fulfil the conditions of the puzzle. Rach town requires one road to enter by, and another to exit by. Bearing this in mind, try finding a route leading forwards out of town 1, and another leading back out of town S, then joining these routes in the middle.
The town will be the 8th visited.
Puzzle w09
- Name: A Smaller E / Make it Smaller
Description: The matches set before you are arranged so that they form the letter E. According to your friend, you can make the E small by moving just one match. Can you accomplish the task your friend has set out for you?
- Hint 1: Because you're going to add a match to the bunch already on the table, it's fair to say you won't physically be making the E any smaller. Since you can't shrink the actual size of the letter, you'll have to think of another way you can make it small.
Place the match on the top section of the E to turn it into a lowercase "e".
Puzzle w10
- Name: Layton's Hatbox
Description: Oh, no! The professor's hatbox has gone missing! Pictured below are four hatboxes that have been broken down and flattened. When reassembled, three of the boxes are identical in every way, but the fourth hatbox differs slightly in its design and belongs to the professor. Can you find it for him?
- Hint 1: Reconstruct the flattened hatboxes in your mind and you'll immediately see what's different. Pay special attention to the hat patterns on each box.
Hatbox B has a different design.
