Each set could vary greatly in composition, number, and design. A common theme with these sets of cards is that there are 3 to 5 cards in the set that belong to one family, and the set is composed of a varying number of families.
Other themed Kazoku-awase sets exist, such as Doubutsu-Awase (動物合わせ, ‘animal matching’) and Juunishi-Awase (十二支合わせ, ‘zodiac matching’) (not to be confused with a set of cards with the same name).
It is possible to be played by 2 players or more, but is best played by 3 or 4 players.

During a player’s turn, they ask any one of the other players for a specific card (Example: A specific family member of a specific person):
Lying is absolutely discouraged in this game.
When a player completes a family, they place it on the table face-down in front of them.
The game continues until all families are completed. The player with the most completed families wins.
