200 countries enter, only one survives

A new track every round, and the last ones to finish are eliminated. The whole elimination takes 40 minutes. • Every round is a new track, fully visible from start to finish. • Some tracks have a trap: whoever falls in is out, and then it closes. • The last marbles to reach the finish are out. Pick your marble before the first round, then watch. #marblerun #marblerace #elimination
