another trick with the tests is to not over-think them. <img src="/ubbthreads/images/graemlins/stupid.gif" alt="" />
example - coincidentally, the third question (#5) is actually the 5th rule-tile of the 16...so like an idiot, my first time through i actually looked for the 'rule' number (13 hours is actually rule-tile 10), not just the number in question. doh!
