Having trouble accessing that. I can't see the tabs, but I see a section on guess the number but it only shows the first guess. By the looks of it, it's pretty similar to what I am doing.

Something else I've noticed is that the easy levels give better destinies than the hard levels. Hard levels give more traps though, and it is actually pretty easy to hit 700 while avoiding destinies (try to use the old memories on the quiz thingy).
