DUO is a UNO free game on the computer, and it is one of the popular chess and card game for home entertainment.
Introduction to gameplay:
1、UNO cards are divided into three types: Number Card (76 cards), Action Card (24 cards), and Wild Card (8 cards), totaling 108 cards.
1）Number Card is composed of 4 colors: red, yellow, blue, and green. Each color has cards with numbers 0-9. There are 19 cards for each color, 1~9 number cards 2 for each color, and 0 number cards 1 for each color.
2）Action Card is also composed of four colors: red, yellow, blue, and green, with a pattern printed on the upper left corner of the card. Their names are "Skip", "Reverse", and "+2 (Draw Two)". There are 8 function cards of each type and 2 cards of each color. They have special functions.
Skip：when playing skip, your next player cannot play cards, the third player play cards.
Reverse：when playing reversal, the sequence will be reversed.
+2：when playing +2, the next player will be fined to draw 2 cards and cannot play cards.
3）Wild Card has a very important position in UNO games. The cards are black, and the names are Wild and +4 (Wild Draw Four, Plus 4), each with 4 cards.
Wild：when playing the color-changing card, you can freely specify the color of the next card (choose 1 out of 4 color).
+4：when playing +4, you can arbitrarily specify the color of the next player's cards. At the same time, the next player must draw 4 cards from the deck, and the next player cannot play card.
1）Players arbitrarily designate one player as the banker, and then each get 7 cards, and the rest are used as a library. The banker takes out the first number card from the deck (take out again if it is not a number card), and then draws the card based on this card, and the game starts. The initial sequence of playing cards is clockwise.
2）It must have the same color or pattern as a card (the last player played) and only one card can be played at a time.
3）If the player has no cards to play, a card will be drawn from the deck. If this card can be played, it can be played immediately, otherwise, it will be skipped and the next player will be play.
4）When there is 1 card left (that is, the penultimate card is played), you must call "UNO", otherwise you must draw 2 cards from the deck.
3、UNO win or lose judgment
1）Players will win a round if all the cards in their hand are played first
2）After one player wins, the rest of the players must start to settle, calculate the total points of the unplayed cards in their hands, and all counts into the winner's score. The person who reaches a certain score first is the final winner.
This game restores the classic gameplay of offline UNO, and the operation is smooth. Under the current situation that offline UNO is no longer popular, online DUO is undoubtedly a boon for UNO fans.
