Think of a number with two digits. For example, 43. Follow the Magic Gopher's instructions and he will amaze you by telling you what number you chose.

Did he get your number right? How does he do it?!

## Comments

when i first played this game I was shocked,but now I know that is not magic and I don't mind it

there are many similar symbols on the paper

and he does not know which symbol you choosed , he shows haphazard....

I am spooked now 3:

he was wrong for several time. and i can not understand how it work

no way he was wrong its impossible not a chance no way not possible

The only possible way is if the person calculated wrong (No offense)

hhhhhh but how does it?

How did he do that-

WAIT A MINUTE

It's pretty easy he says pick a 2 digit number wich all of them equals with the numbers equal to the number nine.

He didn't get it right because I hadn't think of any number at all XD LOL

Merasmus approved

Yeah, he gets it right... because, look, if you try to add both the digits of a two digit number, and subract it with the original, it always gives a multiple of nine. And if look in the paper that the gopher gives us, it has the same symbol for the multiples of nine. He changes the card each time because we'll get a doubt if the same symbol comes again and again.

For example:

65= 6+5=11

65-11=54

54=6*9

Another one:

79=7+9=16

79-16=63

63=7*9

And even though it's the same multiple, you'll get different symbols...

PS: Please don't take this in the wrong way. I don't want to criticise the game. It's just that I've figured out the logic:)

good job:))))))))))))))))))))))))))))))))))))

Of course he gets it right. You subtract the two nubers added from the original number. Example: 43. You subtract 4+3. Instead of taking 43-7, take 43 -3 -4. You will get the same answer. However this proves that no matter what nuber you choose you will always subtract the second number (in this case 3) to get a number that ends with 0 (in this case 40). Then the nuber you subtracted second can only be 1, 2, 3, 4, 5, 6, 7, 8 or 9 And the only possible outcomes will be, 90 - 9 = 81, 80 - 8 = 72, 70 - 7 = 63, 60 - 6 = 54, 50 - 5 = 45, 40 - 4= 36, 30 -3 = 27, 20 - 2 = 18 and 10 - 1 = 9. You might notice that all of these numbers are in the 9's multiplication table. That is because when multiplying by 9 you can instead multiply by 10 and subract the other number. For example: 5*9 = 5*10 - 5 = 50 - 5 = 45. First you add one 5 and then you subtract it again. 9*5 = 9*5 + 5 - 5.And all the symbol 90,81,72,63,54,45,36,27,18 and 9 are the same .

Wrong! I tried THRICE and he got it wrong each time ;]

awesome

fantastic

It does not work.

How amazing !!! That is definitely wonderful ! OMG !! How could he do it ??! i'm gonna be crazy

Hi mavis2002,

Thanks for your message. Sorry you can't see the Magic Gopher. I have tested the game and it's working for me. Can you tell me please what device you're using and which browser and I will check it again.

Best wishes, Jo (LearnEnglish Teens Team)

Amazing

I can not play with any of your games , the only thing that appears in the screen it is a blank space for all the games

Hi Natxu1303,

Thanks for letting us know. I've just tested it and it's working fine for me. We have been having some problems with this game but now it's working again :) I hope it is for you!

How does he do it?I can't understand.That's weird.

Of course he gets it right. You subtract the two nubers added from the original number. Example: 43. You subtract 4+3. Instead of taking 43-7, take 43 -3 -4. You will get the same answer.

Bro, you just cracked the code.

For me, this exercise did not work. I can´t see the game it´s just white. Please help??
