Psychon

Psychon is a simple brain twisting trick that will get you thinking really hard. The application will ask you to make some simple calculations and then will guess psychically the symbol you are looking at.
You don't believe me? Try it!

This application will startle you and your friends, and honestly speaking… will make you shiver!
The solution as to how the application guesses the symbol you are staring at will be included inside the application, although you should first try to understand it yourself.

Oh, and by the way, the game manages to guess your symbol correctly every single time! So if it doesn't, you are not following the instructions!

Have fun!
