Hyakunin Isshu as a game.
Hyakunin isshu is a popular game in Japan. It is played often during the New Year season. A few games are possible using these cards.
Karuta is the most popular game. A reader reads Kaminoku (the upper words) and Shimonoku (the lower words), and the players compete to see how fast they can pick the matching card. The Kaminoku is not written on the cards, so the players who memorize the Kaminoku have an advantage. The player who can get the most cards wins.
The beginning words are "5,7,5" (about 17 characters), called Kaminoku. The second part are "7,7", called Shimonoku.
