|Let's say you chose Number '1', which is pink.
You click on the pink button, so it now knows that your number is either 21, 22, 1, 14, or 6
The next step 'Click on one of the colors below' is meaningless and has no effect on the outcome.
The next step is the houses. Look carefully. The numbers 1, 21, 14, 22 and 6 are all in different houses.
Regardless of what colour you picked, each number of that colour will ALWAYS be in different houses.
So when I click on House A, combined with the color 'Pink', my number can only be Number '1'
The rest of the steps are meaningless and only there to throw you off.
