Gin Rummy's distinct scoring system is one of its distinguishing characteristics. In addition to earning bonus points for going "gin," which happens when a player melds all of therummtir cards without any unmelded cards remaining, players can also earn points by forming melds. Because players must choose between aiming for a higher score or a quick win, this scoring system adds another level of strategy. Players also need to have a keen sense of their opponent's strategy; knowing when to knock (end the round) can be crucial to winning.
