Form a team of 8 players; 4 vote yes and 4 vote no. Thus irrespective of the outcome, 4 are guaranteed to give the correct answer and continue to the next round. In the following round, 2 of the 4 vote yes, and 2 vote no. Thus irrespective of the outcome, 2 are guaranteed to give the correct answer and continue to the next round. In the following round, 1 of the 2 vote yes, and 1 vote no. Thus irrespective of the outcome, 1 is guaranteed to give the correct answer. This could result in either an overall win or a tie with a non team-member. This strategy will enable you to know one of your team will win, but you will not know who it will be.
