Sevens poker game

Familiar with classic games such as Solitaire Victory!
Players with ♥7 must play cards first, then players take turns to play cards

Cards must be played in the same suit and in numerical order (from 7 to K, 6 to A), or 7 of other suits are dealt until everyone runs out of cards.

For example: if someone plays ♥7, the next player must send ♥6 or ♥8, or ♠7, ♣7 or ♦7

When someone is unable to play a card, he must choose to cover a card from his hand to skip this opportunity to play. This card cannot be explicitly shown until the end of the game.

When you fold a card, you can't cut it off. For example, if there is 1.2.6, 6 cannot be covered first, if there is 8.J.K, 8 cannot be covered first.

At the end of the game, the total number of covered cards is calculated. The person with the most cards loses the most, but the person who covers the cards from beginning to end is considered the winner (called a full cover reversal).

When one of the suits "to the end" or "to the end", that is, the suit A or K appears, it is called "cutting the dragon", and the suit is "terminated". That is to say, all remaining cards of this suit in the player's hand will be doomed to be void.
