Okay - I want to set the record straight from the only one star review. This is a very unique and fun ESP "miracle". The cards are well made and the whiteboard and marker are adequate. However, as pointed out by the only other reviewer the directions are very poorly written. In fact I did not even receive them with my order. So I contacted Penguin customer service and within 20 minutes they sent me a PDF with the explanation.(always fantastic customer service) However, the only other reviewer obviously did not spend the necessary time to lay out the cards and figure out what the instructions were trying to poorly explain. But once I laid all the cards out it all fell into place and I had that wonderful "Aha" experience. It is definitely overpriced but I appreciate the "secret" and don't feel totally ripped off because in my opinion sometimes that's what your are paying for. Again, buy it, spend the time to figure it for yourself and enjoy years of ESP fun. If anyone would like to contact me for help I will try to explain the secret without giving it away because you have to really "fill in the blanks" or just have fun and spend the time figuring it out for yourself.

The instructions are terrible, the trick doesn't make sense.
Do MOT buy this unless you have money to waste.
