I've played this twice and it's got it both times, I haven't written down the number or clicked on anything, it's all in your head.

Maths.
Its stupidly obvious how it works too, multiples of 9 are all the same symbol.

Wetwired = noob

How does it work?

There's a braindamaged 6 year old on the other end

She knows what you're thinking

Is it not just using where your mouse pointer is?

Oh dear Wet. What are we gonna do with you.

I still don't understand how it works.

You're a retard then, get your mum to explain it to you.

She is too busy pre-ordering me 360 games.

You explain it :(

It works like this.

The number is always going to be a multiple of nine.

This is because whatever number you pick you subtract 1 multiple of its mod 10 (the units) away from it and 1 multiple of its div 10 (the amount of times 10 will go into the number rounding down).

for example your number is 27. when you subtract 9 (2+7) from it you eliminate the units (7) and subtract a further 2 (the amount of times 10 will go into 27 rounding down). This will result in the number always being a multiple of 9.

10 - 1 = 9
20 - 2 = 18
30 - 3 = 27
40 - 4 = 36
50 - 5 = 45
etc etc.

oh, that's stupidly obvious

Considering the first time i heard this i was 8 and it was a word of mouth joke, i think they jazzed it up pretty well.

oh, that's stupidly obvious

You just have to do two numbers together to see the "trick" i.e..
15 - (1+5) = 9
16 - (1+6) = 9
And then see that every multiple of 9 is the same image. (So dont stare at one number like they tell you to)

The maths would look something like this
Represent the two digit number xy as 10x + y (e.g. 69 = 10*6 + 9 )
10x + y -( x +y) = 9x
You can see no matter what x and y is the result will always be a multiple of 9
