A very simple step-by-step guide for understanding the trick is provided in the following link: http://www.squidoo.com/magic_gopher The Magic Gopher is based on a very simple trick of 9’s. The 2 most important things to note with the symbols are: - The symbols are refreshed and mixed up each time ( the symbol associated with each number changes every time) - Every multiple of (9, 18, 27, etc) has the same symbol each time Basically for EVERY 2 digit number from 11 to 99, subtracting the sum of its digits by the number results in a multiple of 9. This is true for each and every number from 11 till 99. Therefore, whichever number you THINK of in the test will give you the multiple of nine. And since the symbol displayed at the end is always the one that corresponds to all multiples of 9, it can never go wrong. To get a clearer idea, just click through without thinking of any number and check out the symbol corresponding to 9 and all its multiples. That will be the symbol that would come up every time.
