It's a mathmatical outcome, result. There's a card thrick that by the third pick of a row the outcome will be the card the person picked. And the person dealing the cards doesn't know diddly. Works every time.
then when it shows the little houses and asks which house, it is showing 1 number from each color. I picked the 3rd house over. I already told it my color was green. The only number that was green in there was 23....so there you go.
