claiming a win on time

Hi, if the skull appears to claim a win and u continue playing it goes away. Can u claim a win after that on time? Or u only have that one chance when the Skull first appears?

Your opponent obviously moved,thus the skull dissapeared.If you were playing say a 3 day time out with a 7 day timebank,your opponent now has 3 more days after you move in which he must move or the skull will reappear ,at which time you can again claim a win.Hope it is clear enough?Mike
