Roldo is a marble that hides during marble sports events, just like their human counterpart Wally or Waldo. Their first appearance was in the tenth event of Marble League 2017, Archery.
As with other hidden marble challenges, there is a hint that will help find Roldo, accompanied by the difficulty based on, among many others, the length of the video.
