Scoring
When the play has ended the hand is scored. Each player's score for the hand consists of:
- The total value of any bonuses they are entitled to (see table)
- Plus (+) the total value of all the cards they have melded
- Minus (-) the total value of any cards remaining in their hands
After the bonuses have been calculated, the cards used in the Canastas and the melds for each player are counted using the standard card values. The cards remaining in the hands of the players are also counted using the same standard values, but these points count against the player and are subtracted from their score. A cumulative total score is kept for each player. It is possible to have a negative score. When a player has a total of 50,000 or more points at the end of a hand, the game ends and the player with the higher total score wins. The margin of victory is the difference between the scores of the players.
