Indoor or outdoor. Two Truths and a Lie is a great game that works with any age or group size. However, it works best with at least 4-6 people. It can be a quick and unplanned activity. Children take turns. layers tell two truths and one lie. The object of the game is for the other players to guess which statement is the false one. Players vote on which one they believe is the lie and at the end of each round, the person who stated the two truths and one lie, tells which statement is the lie. One way to decide who goes first is to randomly choose one person. Then, if only one person guesses the lie correctly, that person goes next.
