Puzzle No. 004
Picarats: 20


Can you find my house?

Go out the front door of my place and turn left. At the first intersection you come across, take a right. Turn right again at the following intersection, and you'll come face-to-face with the morning sun.

Circle my house.













Hint One: To face the morning sun, one must, of course, look eastward. The map shows north pointing toward the top of the screen, so which direction indicates east?

Hint Two: The rising sun comes from the east. On this map, that means it comes from the right.

Therefore, if you follow the directions, you should be facing to the right after you take your last turn.

Hint Three: Trying to follow the directions from each house only complicates matters. Instead, why not follow the directions in reverse? Needless to say, going backward means the directions you turn will reverse as well.

Start by facing right, then head left down the road, then take a left, then another left....

Solution:













That's right! This is a problem where working backward gets the job done fastest. It takes far too long to check each house individually!
