Jokers can drastically change strategies because players have to choose between using them right away to score points or holding onto them for possible future melds. In a different variation known as "Progressive Rummy Nabobrummy rummy rummy rummy," players earn points over several rounds as opposed to competing for a single-round win. Players may use distinct scoring schemes for different melds in this format, which encourages them to modify their tactics according to where they stand in the game as a whole. Players are encouraged to stay in the game longer & engage in more strategic planning as they take into account both short-term gains and long-term positioning in this variation.
