I imagine this has been done, and if so, my sincere apologies. But…

How the hell does this work?!?

Mathematicians/Computer scientists to the forum please.

4 seconds of that voice were enough, so I’ve no idea how it works

multiples of 9 innit

i think it tracks your mouse position and based on the last pause it guesses that product

edit – no what he says ^^

Perhaps. Except that I didn’t use my mouse.

multiples of 9 innit

Yeah.

There’s a finite amount of valid answers. You subtract the second digit which makes your answer 10, 20, 30, 40… and then the first which makes it 9, 18, 27, 36… If you look carefully at the grid, you’ll see that all those numbers have the same gift.

<mind explodes>

how does it work!!!!??

@Cougar – I get that there are a limited number of options, but I did it 5 times in a row (all correct), then clicked the button 3 more times without picking, then picked numbers again 5 times (all correct again.

If it is doing it by lucky guesses from a limited pool, then it is very lucky!

The maths question they ask you to do always results in a multiple of 9. All the multiples of 9 have the same gift in them. That gift changes each time you play.

ah, cunning – didn’t spot that they were moving the gifts around.

Their example equation is

25-2-5 =18

or algebraicly

(10a+b)-a-b =x
or

10a +b -a -b =x

which reduces to

9a =x

so the answer x will always be a multiple of 9
because they limit the question to a 2 digit number,
a can only = 1,2,3,4,5,6,7,8,9

thus the answer will always be
9,18,27,36,45,54,63,72,81

If you look at the grid, these numbers always have the same gift.
The gifts change on each run to give you the impression of a different result.

Mathematicians/Computer scientists to the forum please.

Or anyone with a little common sense.

EDIT: D’oh.
