In Game 4, teams compete to reach the top of the question ladder by answering successively more difficult questions. As players progress up the "ladder" of questions, every correct answer becomes more valuable. The ladder includes several "milestones," which mark the team's movement to the next level of difficulty. An incorrect answer sends a team back to the last milestone reached. The first team to reach the top of the ladder wins the game (or the round, in multi-round games). Each team receives a set of "safety nets," or tools they can use at their discretion to help answer a question (or pass it on to their opponents!). Depending on the parameters chosen by the administrator, Safety Nets can add a dash of excitement and unpredictability to the game.
