Hey CG!
Um... I keep messing up when trying to figure out peices of this Mastermind, if you have a chance could you please double-check them? 8436498592 - XXOOOOO in particular doesn't seem to agree.
8436498592
xoooo- -o -x
Basically, no 9s and only one 8. 7777888899 - OO would then mean one 7 and one 8
but 5555666677 - XOOO plus some of the others says two 5s and two 6s.
?_?
EDIT oh, and my last guess verified no 7, didn't it?
