Ok, I figured it out after the third time through.... Here's the secret - the chart with the numbers and symbols change each time. I not a mathematician, but I'm going to guess that when you follow their instructions, there are only a few possible numbers that can result. These are very likely all presented with the same symbol on the chart. Then each time you do it, they associate a different symbol with those numbers, so it seems "miraculous"...
