This is the ninth puzzle you will encounter in Professor Layton and the Unwound Future. To access this puzzle, you must return to the Back Room after solving The Odd Clock. In order to solve this puzzle, you must determine which cog should be added to make the top and bottom cogs rotate clockwise.

Contents

[edit] Hints

Hint One
    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 Two
    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 Three
    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 cog C would yield four cogs between the two main cogs, which is the same value as cog A.

[edit] When Failed

Too bad!

Try using the Memo Function to mark the direction in which each cog moves.

[edit] When Completed

Excellent!

The answer is B. If there is an odd number of cogs between the top and bottom cogs, then those two cogs will move in the same direction. However, if there's an even number of cogs between the top and bottom, they will move in opposite directions.

By choosing B, there will be five cogs between the two main cogs, so the direction of their rotation will be the same.

[edit] Solution

Cog B must be inserted.

[edit] Progress

140 Picarats and 29 Hint Coins.
