Since there are many types of rummy, there are also different types of rummy scoring available. However, the way I notice it, there is a common scoring process that is widely being used and agreed upon by players of the game.
Rummy scoring of course depends on what variation one is playing. But it is good to remember that each card has a specific score or points. Regardless of the suit, face cards (King, Queen and Jack) have a score of 10. The numbered cards are scored according to their face value. Take note that the Ace is scored as 1 so a meld of A, 2, 3 is good but not a meld of Q, K, A, which in poker, the Ace has a double-edged purpose being card 1 or the card higher than the King. Rummy scoring in some types also has bonuses when a hand is won. Still some have players agree on a certain score or target score to aim for. Bonus points are given out as well if this goal is reached by a player. Single games or a single hand of other variations of the game also have a player win if he has the least score upon tallying all the cards that are remaining on hand. Some may also agree on a certain rummy scoring process depending on agreements that the players will play.
Scores provide the players of any game to have a track of their progress. Just like any other game, the individual who has the highest score, or least score depending on what game is being played, takes home the bacon. Rummy scoring gives people the same concept, plus bonuses on the side as well for bigger winnings when money is on the side. The rules are not complicated, the scoring is not complicated as well. And the game? Go ask the rummy players, they’ll tell you it’s fun, challenging, and you’ll always wish that lady luck is watching over your shoulders. But of course, always rely on your planning skills to help you gain the upper hand and leave the table with both your wallet and your lips smiling.
