There’s a nifty Flash page called The Flash Mind reader. Basically, you choose any two digit number, add the two digits together and subtract it from the original number. So if you initially choose 76, add 7 + 6 = 13, then 76 - 13 = 63. The Flash Mind Reader will display a symbol tied to whatever number you end with every time.
If you follow the more link below, I will explain how it works.
At first, I couldn’t believe it was getting it right every single time. Then I noticed the symbols changed every time. Then I noticed that whatever the number 27’s symbol was would be the symbol that was shown. In fact, whatever number whose two digits add up to 9 will always be the symbol that will be shown. It didn’t matter what number you started off with, that symbol would be on any number you ended up with.
I was in office and thats when i got this Mind Reader as an attachment… I was really amazed that how the application can predict the symbol… its pretty amazing that without taking any input from the user except the final click in the magic ball it is able to display the correct symbol… it was really amazing… Being very rational i know there is a definite way by which it is displaying the images… but its pretty amazing and its seems to be a big challenge to break the logic working behind this puzzle… However thats my personal desire but i wud really like to appreciate the creator of that application for making a really wonder and amazing thing… it does read the mind pretty accurately… Great job done mate… Regards…
