Pretty easy to figure out...

I'll explain...there are 5 colors, 25 numbers, and 5 houses...Lets say I pick the #11. So I click black, the next screen has nothing to do with the trick, THEN there are 5 houses...NONE of the black numbers from the beginning are in the same house together. There is one black number per house so no matter what you're going to eliminate all other options!

Interesting.

On the second run, I went and chose a house that DIDN'T have the number I picked at the beginning (15) and at the end the first door I opened was not that number. But then I opened the other 2 doors and one of them was 15.

Pretty cool.
