How to play cards

The winner is determined by points

Usually each person is dealt a card in a clockwise direction and the size is generally determined according to the rules. As a trump card, the trump card can beat any non-trump card regardless of the count, but in terms of scoring points, there is no distinction between trump cards and non-trump cards.

The popular "Triumph" in Britain in the 16th and 17th centuries, "Loo" in England in the 18th century, "Spoil Five" in Ireland, and "Ecate" in France in the 19th century (Ecarte), British "Napoleon", American "Euchre" and various bridge cards popular in the 20th century all fall into this category.

Winning or losing is determined by combination

An ancient card game, the key to winning is similar to ancient Chinese dominoes. Poker, as we all know it today, evolved from a series of European-style games. According to the 1801 book "Sports and Pastimes of England", Primero is the earliest card game in England; according to Shakespeare, Henry VIII played Primero on the night of the birth of Queen Elizabeth. Play for fun.

The popular "bragging" card game in the UK evolved from Primero. In addition, there are modern poker games that use mental battles and card theory calculations to win, as well as the "Rummy" card game that uses matching and touching cards to clear one house while other houses calculate penalty points.

Combined gameplay

For example, the "Piquet" card game was developed by aristocrats and upper-class players, especially in France. In addition, the popular card games "Pinochle" and "Bezique" in the United States are also similar, but require the use of two or more decks of cards.
