What is UNO?

UNO is a board game. Players need to shout "UNO" when the last 1 card is left, hence the name. In Spanish/Italian it means "1". UNO is popular all over the world.

UNO cards are divided into digital cards (76 cards), function cards (24 cards) and general cards (8 cards), totaling 108 cards.

Digital cards are composed of four colors: red, yellow, blue and green, and each color has digital cards 0~9. Each color has 19 digital cards, 1~9 each color has 2 digital cards, 0 each color has 1 digital cards. They are the most basic cards in UNO.

UNO advanced rules:

1, +4 Complete rule: +4 Only when the player does not have the same color as the reference card (excluding the same number or function, the general card has no color), can the card be legally played. The next family has the right to question whether your card is legal, and then you have to show it to him (called questioning or reporting).

If you play cards legally, you will be fined 4 cards at home and draw 2 cards from the pile as an extra punishment; On the other hand, if you violate the rules, you will be fined 4 cards, and you don't need to draw cards next time.

Whether the next player signs up for +4 or not, he will be skipped, that is, the next player is the next player.

After adding such rules, +4 is full of variables, which also limits the use of +4 and derives many advanced skills.

2. Complete rules about the first card: each player draws a card first, and the dealer with the largest number (if it is not a digital card, then take it away). Then each person takes seven cards, and the rest is used as a library. Then take out the first card from the pile, and the dealer will play cards according to this card (there will be a table below), and the game will begin. The original order of playing cards is clockwise.
