I can't work it out, but it gets it right every time.

 

Just follow the easy instructions. Tell your friends.

I knew you were going to say that 8-)

Did this twice with my wife. We both chose different numbers but the answers were the same.

 

If you notice each and every time the remaining number is 9 or if a two digit number when added together make 9.

 

So quite simply it is a mathematical trick.

I think it's where you hover your mouse... most people look with their mouse, and hover their mouse over the one they are choosing... Try doing it whilst keeping your mouse still

my mouse was still, didn't use it at all. It is a mathematical trick.

Definitely a mathematic one. You will notice that the same gifts are repeated on certain numbers.

 

Still quite clever though.

As SOD'EM and others have said, every answer will be a multiple of 9. Take a look at the chart and you'll notice that every multiple of 9 (so 9, 18, 27, etc.) has the exact same gift.

 

I took the script running it apart and noticed the programmer has rather craftily added in a routine that changes the number table every time you look at it, so the gift in box 9 on one go will be different from the gift in box 9 on the next, and so on.

 

A fun little distraction though.
