The player with the 7 of hearts must play the card first, after which the players take turns

Cards must be played in consecutive suits and in numerical order (up from 7 to K, down from 6 to A), or deal 7s of other suits until everyone runs out of cards in their hand.

For example: someone throws a 7 of hearts, the next player must throw a 6 of hearts or an 8 of hearts, or other 7s

When someone has no way to play a card, they must choose to cover a card from their hand to skip this chance to play a card. This card cannot be revealed until the end of the game.

When folded, the card cannot be broken. For example, if there is 1.2.6, then 6 cannot be covered first, and if there is 8.J.K, then 8 cannot be covered first.

At the end of the game, the sum of the points of the covered cards is calculated. The person with the most cards loses the most, but the person who covers the cards from the beginning to the end wins the most (called all-fold reversal).

When one of the suits "ends to the end" or "ends to the end", that is, the suit A or K appears, it is called "Zhan Long", and the suit is "terminated". That is to say, the remaining cards of this suit in all players' hands will be doomed to void.

Card comparison method:
Thirteen folds 〉hands 7 〉hands off 〉the number of folded cards is small 〉the number of folded cards is small 〉the first order of play

Points calculation: loser folds 1 point 1 point
When the winner meets the following conditions, the points are calculated according to the multiplier
Thirteen covers x5 times
Hands off 7x4x
Hand off x2 times
