FREE WILL- this is in my opinion the cleanest version of free will. No equivoque and no outs. The prediction is never switched and can be in the spectators pocket. The principle can be used for so many other things.
WORD GUESS- the spectator writes down a word and you can divine it without ever touching the billet. He doesn’t even have to write it. He can just think it and you will still be able to divine it in a matter of seconds. https://youtu.be/zr0FdVO49aw
