Difficulty:** (1.8)



At a + shaped intersection, four different-coloured houses are at the four corners of the intersection so that each house is separated by a road. All you know about the colours of the houses is:

1. The blue house is directly north of the purple house.

2. The orange house is directly west of the green house.

What colours are the two houses that are across the road from the green house?

Excellent. I read the first two conditions, thought "Wha--?" and then slowly realized the answer.

I never know how to figure these things out, but after reading Zembobo's theory it made a lot more sense. Thanks Zem! :D

Good teaser, but a little logic made this easy to figure out. :D :D

The first clue was misleading, but I still enjoyed the riddle!!!

I din't deem the first clue misleading, but it did require you to break the mental set that the roads are oriented east-west and north-south, rather than northeast-southwest and northwest-southeast. Without that realization, which, btw, did not come to my 78-year-old brain instantaneously, the puzzle is impossible to solve.

"didn't", not "din't", though I guess "din't" works, for a lazy enunciator.

Brilliant and ingenious!! I stared at it saying "...not possible" for a couple of minutes, then read the answer. D'oh!!! However, I would change the first sentence to: "There is an intersection of two perpendicular roads." or "Two roads intersect at right angles."
