🅾️ to display all captured cards

Knowledge of koi-koi is obviously highly recommended to enjoy the game, but here a quick rundown of the rules :

An hanaduda deck contains 48 cards, 4 cards for each month :

Each round, you try to capture card by matching a card from your hand with a card from the table with the corresponding month, then you reveal the top card of the deck and try to match it in the same way.

If you play a card without a match on the table, it will be discarded on the table.

The goal of the game is to gain points by forming yaku, and either ending the round to score your points (calling shōbu), or gamble your unscored points to to double them (calling koi-koi).
