How to use Playing Cards for Hanafuda
A common game played in Japan using hanafuda cards is called "Koi Koi". the phrase "koi koi" means "Come on" in Japanese. This is a matching game. There are various "Yaku" or "sets", similar to Poker, that grant you different points.

Example, June is "Peony".
RULES OF KOI-KOI
Players: 2
Goal: Form special card combinations called "Yaku" to collect points.
Game Flow: Determine the dealer by each player drawing a card from the deck. Whoever draws a card from the earliest month is the dealer. If both players draw the same month, continue to draw until one player has the earliest month. Once dealer is determined, you can choose between 6 or 12 hands or rounds.
DEALING CARDS: begin by placing 8 cards face up on the table. Deal 8 cards to each player. Set the remaining deck to the side as a draw pile.
If your original hand contains Yaku, you are immediately awarded points, and can play them before the next hand.
EACH PLAYERS TURN: Each player begins by
1. Matching hands: Player can select a card from his hand to match (month/flower) to a card on the table. If there are 2 matches on the table, the player can select 1. if there are 3 matches on the table, the player are matched to GAIN. (ref. #3)
If player doesn't have a match, the player must lay down one card from his hand to the table.
2. matching from the draw pile: A player draws one card from the draw pile and places it face up on the table. If the card matches any month/flower, the player must match that card. If there are more than 1 card matched on the table, follow 1. Matching hands rules.
3. gaining cards: Once cards are matched, player collects his cards into a point pile. Once the player creates a "Yaku", player now can either "Koi-koi" or "Stop"
4. Koi-koi or stop: If a player calls "Stop", the player gains all the points in their "Yaku". After that, a new month or hand is dealt and the player becomes the dealer for the next round.
If a player believes they can form additional "Yaku", the player can call "Koi-koi" to continue play. However, if the opponent can form a "Yaku" before the player who called "koi-koi", the opponents points are doubled. Only the winner of the round can collect points.
