Welcome to a magical experience! I'm about to read your mind through your screen. Follow the instructions carefully and prepare to be amazed!
Think of one of these symbols and click on it:
Now, I'll perform some calculations with your symbol...
Multiplying by secret numbers...
Analyzing your choice pattern...
Processing the mystical energies...
Concentrating on your thoughts...
Amazing, isn't it? I read your mind through the screen!
This trick works through clever programming. When you selected a symbol, the website stored your choice. The "calculations" were just for show - creating suspense and the illusion of a complex process. But in reality I just regurgitated the symbol that you chose.
