At NMT, if your taw is in the ring at the end of your turn, you must remove it. In informal games, if your taw is in the ring, it becomes a legitimate target and any player who hits it out collects a forfeit from you. Players should agree in advance whether to use this rule. Play alternates until one player has knocked a majority of the marbles out of the ring. The process of picking the best possible position for starting is referred to as 'taking rounders'.
Second player trys to hit the first player's marble.
If he hits it, he collects both marbles. If the two marbles are close enough, he can attempt to 'span' them. He places his thumb on his own marble and his index finger on his opponent's marble. He then draws his hand up while bringing his fingers together. If the two marbles hit, he collects both marbles.
