What is Nana: This game aims to "put 3 cards of the same number." When your turn is turned, reveal the cards and all three are the same number, then challenge successfully. If a different number is released, it will be a challenge failure. The play method is the same as the "nervous" playing card game, but the feeling of playing is completely different. Neurodepression is a game of flipping the place card, but Nana will reveal someone's hand. In addition, your hand can only be published with the largest number or the smallest number. In that rule, the first person who purchased three challenges wins the game. Basically, you will find 3 identical cards, but you will see many things in the process. For example, if a person's largest number is 8. Numbers are only 1 to 12 so you know that your hand is just a small number. If you have 2 "1" cards in your hand, you may be able to reveal those "people who seem to have a small number." (Of course, it is not necessary...) Nana is the interesting point of being able to enjoy reasoning thoughts even though it is a very simple rule.
