Usually it's just luck, of course you have to use common sense. If
the number is at 9 it's a 90% it'll be lower than 9, of course that
10% can lead too your demise but you got to consider this to your
consideration. If it's at 5, the best thing to do would probably be
flipping a coin in coin flip.
Yes, it can happen.
People often think the PH sprites are bland. Do they shade? Well,
yes they do. You'll be surprised how much care is taken for these
sprites.
It’s mostly luck but just remember your odds, I.e 6 you’d go lower
and 4 you’d go higher. 5 I always do higher and I got the 15
correct tries for the challenge already.
