The clown in poker is a ghost card. There are two clown cards in poker, which refer to the big and small kings. They are also called big and small ghosts in some places. The two clowns represent the sun and the moon.

When playing cards were first introduced to the United States, there were no Joker cards, but manufacturers who sold playing cards often put a few extra "billboards" with the same texture as playing cards in a deck of cards. , Joker appears as an interactive image with advertising products or text, so the Joker card appeared. And some of our domestic playing cards have advertisements printed on the clown cards.

There are two biggest reasons for the clown card, which are:

1. The divination effect of tarot cards. The biggest clown card is good luck.

2. The clown card can also replace any card in different poker games.

The origin of ghost cards

Invented by the French in the 14th century, there were only 52 cards at the beginning. Around 1850, some poker manufacturers began to add the 53rd card to the cards. At that time, this card was only used as a replacement card or advertisement. The 53rd card mainly had the following forms:

1. Blank card, that is, a card without any printing on the front. This card is mainly used as a replacement card. When a card in the card is lost, it can be replaced with this card.

2. Trademark card. This card is printed with the trademark of the poker factory. It can be used as a replacement card and also plays an advertising role.

3. Billboard, a pair of ordinary playing cards plus a product advertisement. This card may be the predecessor of today's advertising poker. Billboards of this form can be seen.

4. Rule cards. Whist bridge was already very popular at that time. The scoring method printed on this card was very popular among players. Many foreign poker cards today also have this card.

The card at that time was not called JOKER, but called: "Extra card", which means extra card.

Since many cards have 53 cards, there are many card games played with 53 cards.
