I guess we'll find out the answers to all these, assuming Buzzr is going to air the entire run.
Has this ever happened?
A 5 square win (considering the game's pacing, that show likely only had 2 rounds of gameplay since it was rare that they played more than 15 questions a show)
A 6-6 tie in round 2
A 6-6 tie in round 1 (Very highly unlikely, as the questions were purposely very open ended)
