1. Re-deal: You can reshuffle the cards and re-deal the cards, so that the players can play the landlord again. This is the most common way to deal with it, which can give each player a new chance.
2. Automatically assign the landlord: If three players are not called the landlord, the game can automatically assign a player as the landlord. The landlord is usually determined according to certain rules. For example, it can be decided according to the size of the cards or by drawing lots.
It should be noted that due to the rules of the game, room setting or manual intervention, the specific treatment methods may be different. In a specific game, the treatment scheme can be determined according to the rules of the game or the instructions of the room manager. Therefore, it is best to find relevant information in the rules of the game or the room description.
