Mind Reading Illusion

Posted in Fun, Skepdude by Skepdude on October 24, 2008

It took me a bit to figure this trick out, but it’s quite cool. Go play the game first then come back for the solution to how it works.

You’re back? It was fun right? Now here is hot it works:

Take any double digit number that starts with 1 and follow the procedure. You will always end up with 9. Try it. (10-1-0=9, 15-1-5=9)

Take any double digit number that starts with 2 and follow the procedure. You will always end up with 18. Try it. (23-3-2=18, 27-7-2= 18)

And so on and so on. Look at the table. The symbol next to the numbers 9, 18, 27, 36 and so on is always the same, because regardless of the double digit number you choose,  you’re always guaranteed to come up with 9, 18, 27, 36 and so on. Every time you play, the game shuffles the symbols around, which creates the illusion they’re after.

Test: Use the same number twice. You’ll get two different symbols.

Clever, but I’m clever too.
