This is the one hundred and twelfth puzzle you will encounter in Professor Layton and the Diabolical Box. To access this puzzle, you must talk to Duke. In order to solve this puzzle, you must determine the fewest number of connections it takes to keep the light turned on no matter which points make contact.


[edit] Hints

Hint One
    "No matter whether you hold contact points A and B, B and C, or A and C together, the light stays on."

    This might make you think that the electricity has to run through all three of these connections, but at the same time, the positive and negative signals need to be isolated from each other, which makes things more difficult. Read the conditions you have to meet again as carefully as you can.

Hint Two
    You might be tempted to construct something resembling a proper wiring job, but that won't do the trick here. Be flexible in your thinking about what will get the job done!

Hint Three
    You only need to draw one wire!

[edit] When Failed

Too bad!

Are you sure your solution meets all the conditions set out by the puzzle?

[edit] When Completed

Bright idea!

All you really have to do is connect that lightbulb to the battery. The puzzle tells you that the light stays lit even when contact points A and B, A and C, or B and C touch. Naturally, the light will also stay lit even when none of those points touch.

[edit] Solution


Draw a line as shown.
