　　The so-called chess game is the floorboard of chess game and card game. Chess and card games have flourished since the Ming and Qing Dynasties. Mainly includes poker, landlords, China chess, military chess, gobang, mahjong and so on.from BL777 Casino Login From the reference value, it can also bring a lot of inspiration to other industries. https://www.bl77777.com/

　　Chess and card games can be divided into poker, landlord fighting, mahjong, China chess, Go and military chess. It can be said that the richness of chess and card games is completely beyond your imagination.

　　In China, Landlord Fighting, Mahjong and China Chess can be said to be the most well-known players. After all, China Chess can be said to be the quintessence of China, and Landlord Fighting Mahjong has become omniscient among the people. People over three years old basically know these chess games, so today we will talk about the unknown contents of these chess games.

　　Dou dizhu, a popular Chinese poker; fighting the landlord

　　Nowadays, most of the landlord fighting industries rely on online. Since the first full game of JJ Landlord Fighting was held online, the offline card game has not been adopted, and now online landlords are in full bloom. Online landlords have occupied half of the landlord fighting world, while offline landlords have struggled to survive in the residual wind of online landlords. With the outbreak of the epidemic in the past 20 years, online landlords have developed to a kind of existence beyond the peak.

　　Nowadays, online landlord fighting, JJ landlord fighting and happy landlord fighting still occupy more than 80% of the market, while other games such as Zen Tour Landlord Fighting and National Landlord Fighting occupy 20% of the market. Although these games occupy 20% of the market, their market share is getting less and less under the oppression of JJ landlord fighting and happy landlord fighting. At this time, a new landlord fighting game is needed to enter the market, just like the catfish effect, to activate the vitality of landlord fighting.

　　In the chess game, listening to cards is a skill, and listening to cards is a craft. Listening to cards means that you are about to enter the stage of Hu cards, which means that the final victory will not be too far away. Generally, players on the field basically start to listen to cards at the later stage of the game. At this time, whoever listens well and can master the skills of listening to cards will win the game earlier. Today, the new recruitment game will come to say for everyone?So, BL777 On the contrary, there is still a lot of room to play. https://www.bl77777.com/

　　1. Listen to multiple cards-in a card type, players usually choose to listen to several cards. For example, 2,345,000, and the cards drawn at this time are 20,000 and 50,000. If it’s 2,345,600, then the draw cards are 10,000, 40,000 and 70,000. However, players need to pay attention to the fact that if some of the cards in Hu are likely to destroy the overall card type, such as one-stop, flat Hu and so on.

　　2. Listening is monotonous-it means that when players listen to cards, they just listen to a single card and want to make a pair.

　　3. Listen to the hole-for a simple example, if the cards in the player’s hand are 20,000 or 40,000, then the card type that the player listens to at this time is 30,000 holes.

　　4. Listen to the side card-listening to the side card is similar to listening to the hole. For example, at this time, the cards in the player’s hand are 70,000 and 80,000, so the card type that the player listens to at this time is 90,000.

　　5. Listen right-if there are two pairs in the player’s hand, at this time, you only need to make another set of engravings, and the other set will be used as a card. In this case, the player needs to listen to two cards, and this card drawing type is called listening right.

　　When listening to cards, players must pay attention to the card type of their family, and try not to listen to the same card type as their family, so as not to be called Hu by their family in advance. If your last family happens to be the dealer of the game in this bureau, it’s like avoiding listening to the same cards as your last family. If you can hide, you can hide!
