I didn't see a review for this effect so I thought I'd be the first (yay!) So when hearing of this effect, I thought it would be 100% propless. It is not (kinda?) you will need access to the internet, so the spectator will need a phone (or you can provide your own) or you can just print out what you need to perform the trick (maybe include another trick with it) the method itself is very simple, although depending where you are from, there will be some trial and error to get your outs ready, but it's very simple. From an outsiders point of view it's very fooling, but performing for someone that knows a bit of mentalism, might catch on quick. This trick does involve forces, mainly numbers, which is covered in the video, no problem, it's not my favorite but if it works, it works, if you can force letters then most of the script is gone, and it's just basic mind reading, I'd say this trick is perfect for a beginner. Which I would consider myself but I don't really see myself doing this. Great trick but I don't think it's worth 20 (in my opinion) possibly 10 or 15. It's a cool trick but if you studied mentalism, you wouldn't really learn nothing new except a new way to form it out.
