This is how they know your number every time. When you pick the color where your number is, 
they know it’s one of 5 numbers. Then when they tell you to pick the house only one number from
the first 5 is also in the house you pick. 
 
So there is no guess work for them. Picking a square color has nothing to do with finding your 
number or picking a crystal ball, it just makes you feel like it’s more of a mystery.  
 
Now have I thoroughly confused you?  :-)
