game rule

Divide the 32 dominoes into four pieces and eight pieces, and each person touches eight cards according to the rules of touching cards. The dealer started playing cards, and each player took turns playing cards. A card is followed by a card, and a deck of cards is followed by a deck of cards.

If you can't pick up your hand, you must cancel it (you can't pick up your hand, follow it with the smallest or useless card). The cancelled cards must be word-for-word, so that the opponent does not know what cards to cancel. After a round, the player with the biggest card on the table will get all the cards on the table calculated in front of him. The more cards a player receives, the more points he gets.
