Card drawing system refers to the process in which players draw virtual objects or characters that appear randomly in the game by consuming virtual currency or actually recharging a certain amount. Usually the game will set a certain drawing and appearance probability, so that players have the opportunity to draw rare virtual objects or characters. Some games also provide different benefits and card drawing opportunities according to the player's consumption.

Card drawing system is widely used in some games, such as Netease's "Yin" and "the glory of the king", attracting a large number of players. Some players can get what they want by drawing cards, but some players spend a lot of time and money because they can't draw the virtual objects or characters they want. Due to the randomness of the card drawing system, it is considered as a gambling behavior in some countries and regions, which needs to be considered from the aspects of legality and supervision.

The card drawing system has been questioned and disputed in recent years, but it is still an important element of some games. Some games have formulated fairer and more transparent card drawing rules to attract more players. In the future, the card drawing system may continue to develop. For example, the game may use artificial intelligence and other technologies to more accurately adjust and match the probability and content of drawing cards to provide a better game experience and fairness.
