20336- i wonder if being sleepy and not caring helped? anyway i tried to keep the largest number in a corner down at the bottom and have a pyramid of successively increasing numbers emanating from it- it seemed to work. wasn't able to always keep it in the corner, but at the end i had enough space to work with that i decided to move everything up so i could get around to the other side of it where my 512 number was- and i got lucky
i begin to think that the number score you're given is just a random number :/ maybe i'll try this again changing only one of my answers at a time on multiple tests and see if it consistently raises/lowers my score
