Form your group into teams of 2-5 people. One person from each team opens The Estimation Game on their phone or laptop and signs in with their Google account. Teams can go at their own pace through ~10 questions in two rounds. They'll win points for good estimates, and see how their score compares to other teams in your group and around the world on the leaderboard. The team with the highest score wins! See it in action with the demo game.
