One player places the event on the timeline. Before it locks, another may challenge and put it somewhere else instead. A correct challenge steals the point and keeps the streak alive; a failed one pays the player who was challenged, which is what stops challenging being free. The referee never sees the year until the placement resolves, so there is nothing to read off their face.

Players: Three or more people in the car.

Driver: Places events, and challenges the placements they think are wrong.

The bar: A streak long enough that luck cannot account for it.
