Nanadium-it is only 7 grams used in Japan The material of a dream of producing 10 years worth of electricity. The synthesis of Nanadium is a top honor for scientists. Make the synthesis a success faster than anyone and get rid of it! Nobel Prize! Change the hand with a card draft, and make the number close to 7 with the combination of 2 cards while predicting the other hand! However, if there are players who made the same numbers, they will all be invalid! It is not okay to make 7! It is a card game that you will not only bring your own number close to 7, but you also need to predict the figures of other players, and you will want to play many times in a short amount of time with a heavy read-in balance in a minimum.
