Top Ten Quiz

From BoardGameGeek:

On each card you will find a chart with ten correct answers. You are not allowed to look at the cards or shuffle them before you start the game! Try to gain as many points as possible with your team. You will achieve this by giving up to ten correct answers for each Top-Ten-Chart. Form two teams, and choose one player of each team as that team's captain during each round. The captains special rule is that they are not allowed to give any answers on their own. Instead, they must estimate the number of correct answers given by their team. The team with the most points after seven rounds wins! -description from publisher's website
