It is fully plausible my logic has failed me, but I have it narrowed down to 3 possibilities. I figure it is "get it right here on guess 7" or lose by tie-breaker by getting it right on guess 8 with 1-or-2 fewer total result-icons.
So, as I have done a couple times in this competition I toss it up to lady luck and rub the Oracle's belly for favor:
#7 -
Oh wait, I misinterpreted what you said here. You're right. You needed to solve it on turn 7 to win. That means theelkspeaks won there.
Congratulations for theelkspeaks then, who is the biggest Mastermind who won the Mastermind Tournament!
Also congratulations for rob, who was a worthy adversary!
