Ugh, even this game isn't immune to griefers.
you can make any game have griefers if you add a mean to get your self annoyed at.
tic tak toe can have griefers if you get annoyed at people placing O in the middle.
don't get annoyed at any little thing in a free game and no more griefers.
I usually find unusual gameplay FUN adds a different take to the same playthrough.
