The players are all aboard a hot air balloon which is rising into the sky. Each turn, a steadily increasing number of specialized dice are rolled to determine how difficult it will be for the balloon to stay airborne. Then one of the players attempts to play the appropriate number of cards dictated by the dice. If the player is unsuccessful, the balloon and all its occupants suddenly plummet to their death. The trick is that players are each given the opportunity to bail out of the balloon and take points earned up to that point, depending on the faith they have in the pilot for the turn. - BoardGameGeek
