Maximum number of cards you can hold
The maximum number of cards you can hold game setting defines how many whole cards that a player or team can hold onto without being forced to play or discard some.
If a player or team holds more whole cards than this limit specifies, they will get a red message in the top-left corner of the game letting them know how many cards they must play that turn.
Partial cards do not apply. The card only counts towards your limit once you acquire all of the pieces, and therefore is playable.
