In certain variations, for example, wild cards may be added, which can be used to replace any card in a meld and give strategy and decision-making a fun new twist. Different scoring methods or regulsata kegations governing the number of cards that must be melded before a player can lay down their hand are further examples of variations. It's important for players to understand that house rules may vary from those of regular gameplay. These regulations may specify the conditions under which players may draw from the discard pile or differ in the number of cards dealt at the start of each round.
