The game asks you to select any two digit number (example 25). Next, you are to subtract the both the first and second digits from your number (example: 25 – 2 – 5 = 18). Then you are to select a gift from a grid of all possible answers. In the final page, Regifting Robin correctly guesses your gift. So how does this nifty trick work?

The equation can be represented as: (10*x + y) - x - y = 9*x

Using our example, x = 2 and y = 5, so that’s (10*2 + 5) – 2 – 5 = 9*2 = 18.

In the gift grid, each 9*x box has the same gift, e.g., the boxes numbered 9, 18, 27, 36, etc. all are marked “Bath Salts.”

The selected gift is changed each time to make the trick seem more real.



my first number I chose was 24 so this is how it’s broken down

(10 x 2=20) then do 20+4=24 right

then do what they asked 24-2-4= 18

SO now 18/2=9 (18 devided by 2 equals 9)

How they guess YOUR ANSWER correctly, all of the game is based off of the numer 9, all of the multiples of 9= 9, 18, 27, 36, 45 etc. so the gifts just keep changing as you keep trying to figure it out! so basically 9 18 27 36 45 and so on, are all the same gifts, and they change everytime you try again. So when you use the formula that they gave to you 25-2-5 will end up in the multiples of 9.
