Nana is a card game in which players are looking for three of a kind. Each player is dealt three cards and the remained are laid out facedown on the table. On a turn, you either reveal the highest or lowest card from your hand, or turn over a card on the table. Then you do it again. If the two cards show the same number, you repeat a third time. if they do not, the cards are returned to where they came from and your turn ends. If you reveal three cards showing the same number, you take these cards as a set and place them in front of you. If you are the first player to collect three sets, you win.
