The game mechanics of this game are very rich and diverse. First of all, the game is divided into two modes, one is the classic mode and the other is the happy mode. In classic mode, each player gets a number card, that is, each card has a corresponding number card on it. These cards have a total of four colors, red, yellow, blue, and green. If your card is the same color or the same number as the previous card, you can play. If you have a "prohibited card" in your hand, you can prohibit the previous or next player from playing cards. That is to say, when you know that your next person has no cards of the current corresponding color, the forbidden cards of the same color in your hand can not be played first, so that the next player can get a card because if you play Banned cards are like helping him. In addition to forbidden cards, there are some flip cards in the game. With flip cards, players can play these cards with the same color or the same color as the previous card when they are flipped. Among these cards are some wild cards, which can be played at any time.

In addition to this classic mode, there is also a happy mode. In happy mode, there are some new functional cards, such as the fan card, which is red and has a fan-like shape inside. This card allows you to play all the cards of the same color as the row in your hand at one time, as many as you want, so it is very fast. But his weakness of it is also very obvious. You can let everyone know that you don't have cards of this color in your hand, so it is easy to be run by other players. Both game modes have their own characteristics and are very interesting. When playing this game, it is recommended that players do not rush to rank others at first, because the most powerful rank is when others rank the least. When stacking up in the happy field, players should ensure that they have several different cards in their hands. If it is a two-player mode, they should also observe whether their teammates can afford their cards.
