The answer you guessed was not correct. Ten was the answer.
Every cell that is a perfect square will remain open
(1, 4, 9, 16, 25, 36, 49, 64, 81, and 100). If a number is not
a perfect square, then it has an even number of divisors,
therefore it will be "toggled" an even number of times and
end up where it started (closed). Perfect squares have an odd
number of divisors, so they will end up the opposite of where
they started (open).
Now on to grim's riddle. hmmmmmmm

My habitation's in a wood,
And I'm at anyone's command.
I often do more harm than good;
If once I get the upper hand,
I never fear a champion's frown;
Stout things I often times have done;
Brave soldiers, I can fell them down,
I never fear their sword nor gun.
