Hanafuda Yuukyou Den - Nagarebana Oryuu (Japan) (Unl)

Hanafuda Yuukyou Den - Nagarebana Oryuu is a traditional Japanese Hanafuda card game for the NES. The game focuses on the Koi-Koi variant, a popular Hanafuda game where players aim to form combinations of cards (called yaku) that yield higher scores than their opponent.

Each round begins with a certain number of cards dealt to the players and a number of cards face-up on the table. The primary goal is to match cards from your hand or a card drawn from the deck with cards on the table that share the same month. For example, if you have a January (Pine) card in your hand, you can match it with another Pine card on the table.

After making a match, the player draws an additional card from the deck and attempts to match it as well. If no match can be made, that card is placed face-up on the table. This process continues until a player declares "Koi-Koi" (to continue playing for more points) or "Shobu" (to stop and score).

The yaku (winning card combinations) include various types, from simple sets like Tanzaku (ribbon cards) and Tane (animal/special object cards) to more complex ones like Hikari (bright cards). The point value of each yaku varies, and players need strategy to collect the right cards to form the highest-scoring combinations.

With the "Yuukyou Den" (chivalrous/yakuza legend) setting and the character Oryuu, the game likely features a subtle storyline or opponents designed around this theme, offering an experience that is not just a pure card game but also a small adventure within the world of traditional Japanese gambling.
