When you have trivia quizzes with multiple rounds, and multiple questions per round, CREATE A LEADERBOARD THAT ALLOWS USERS TO CHOOSE WHICH SLIDES THE LEADERBOARD APPLIES TO. This would allow users to score ONLY the questions in each round instead of a cumulative score for all questions that came before in the quiz. For example, reset all scores at the end of each round for all players so all players have an equal chance to be the winner for a round. Also CREATE AN OVERALL LEADERBOARD that would combine total scores for players from each round to provide an overall total and designate an overall winner of trivia.
