What Card game is played with 15 cards.?

There isn't a single card game that is *exclusively* played with 15 cards. However, there are several games that use a subset of a standard 52-card deck that could involve 15 cards.

Here are a few possibilities:

* Cribbage: This game typically uses a 52-card deck, but only 12 cards are dealt to each player (6 each, for two players). The remaining cards are placed in a pile called the "crib." So, you could be playing Cribbage with 15 cards (12 dealt + 3 in the crib).

* Pinochle: This game uses a double deck of 48 cards, and each player is dealt 12 cards. You could easily use a subset of this deck, or play with a smaller number of players, resulting in 15 cards being used.

* Canasta: This game utilizes two decks of cards and involves dealing a hand of 11 cards to each player. You could theoretically play with a smaller number of players and deal 15 cards, or use only one deck and adjust the rules accordingly.

* Rummy Variations: Many Rummy variations exist, and some could be played with 15 cards by adjusting the rules and number of players.

Ultimately, the specific card game you're thinking of depends on the rules and variations being used. If you can give me more details about the gameplay, I might be able to narrow it down!
