i chose 56 but instead it told me 6

This is matemathics. And only 1 level? not very impressive or entertaining.

to be honest it was a little lame, and was also wrong, i choose 55 but instead it told me 47 soooooo no it doesn't work sorry to say

Doesn't do anything. You spelled "guess" wrong.

For something so simple it would have been a lot better to at least make an effort with the graphics. I've also seen this many times before, tv magicans do this one a lot. Good try though.
