I got the first Roll right, by pure chance. That did kinda confuse me, because I thought I had already figured out the pattern. After 3 further roles, which made all my theories of arrangment, colour schemes, mathematical formulas or correlation of numbers disappear, i knew what was going on the fifth time, sixth throw confirmed my theory. Nonetheless I think it isn't really that hard, just another indicator for the disadvantage of people that tend to think in a restricted way. For mathematicians it is probably going to take a lot longer then ten minutes.
