Magic Gopher

Instructions: 

Think of a number with two digits. For example 43.

Now add the two numbers together. For exammple 4 + 3 = 7.

Next, subtract the new number from your orginal number. For example 43 - 7 = 36.

Finally, look at the symbol next to your number. Remember it.

Now the Magic Gohper will read your mind and tell you what your symbol is. Watch carefully.

Look, if you take a number N=10xa+b, where b is between 0 and 9 and a between 1 and 9. Ok?
So, you have (10a+b) - (a+b)=9a, right ? After that, look at the multiples of 9, they have all the same sign. When you have your result (ex: 12>1+2=3>12-3=9), which is a multiple of 9. The squirrel must just say these sign and he's right ! Understood, now ?

Woof4, look, if you take N=10a+b, where b is between 0 and 9, and a between 1and 9, you have :
(10a+b) - (a+b) = 9a. Ok? So, the result can only be a multiple of 9 : 9,18, 27, 36, 45, 54, 63, 72, 81, 90. After that, look at the signs in the table. You can notice that all the multiplies of 9 have the same sign. The squirrel has just to show this sign and he's right. You see, it's no magic, but mathematics.

Hi Haider7427. Let me reassure you that our games 100% do not use the camera or microphone. If we ever add a game that does, the game will say so clearly. Thanks for your comment :)

Oh, it is simple algebra: always the symbol from the card is following that numbers: 9, 18, 27, 36, 45, 54, 63, 72, 81... But this squirrel is clever, realy! :)

Hi hannaramm57,
 Thanks for letting us know. Is it loading for you now ? I've just tested it and it's working fine for me.  Are you using Chrome, Internet Explorer, Safari or another browser? Perhaps you could try using a different browser and see it that works. 
Let us know how you get on ...

Hi Sarahappy,
I'm sorry it's not working for you ... I've just tried it again and it's working fine for me. Take a look at my comment above which will give you some ideas to try out. I hope you manage to get it working.
