NOTE: The instructions below are for the general game of UNO.

UNO is a classic, with millions of sets sold over the years. Like most card games, UNO trains concentration, memory, and reaction time.

When the UNO online card game window first opens, the instructions display above the UNO board for 40 seconds. If you already know how to play UNO, click the middle of the instructions to close it and start playing.

HOW TO PLAY.  The object of UNO is to get rid of all your cards before the other players get rid of theirs. You get rid of cards from your hand by discarding cards that match the top card in the Discard pile in the center of the table.

The game keeps track of your score during each round.

The game is called "UNO" (which means "one" in Spanish) because when you get down to only one card in your hand you are supposed to shout the word "UNO".

If you forget to say UNO, you are penalized by having to draw two more cards from the pile. Of course, it's rather silly to yell UNO at a computer, so in this UNO online card game you need to quickly press the red UNO button instead (see below).

UNO is a really fun game. It's even more enjoyable when you play against real people with real UNO cards. I own UNO and have played it with family and friends for years.

UNO Rules

Each player starts the game with 7 cards. The general rules for UNO game play are as follows:

• OBJECTIVES. This UNO game is played in 3 rounds. During each round, try to get rid of all the cards in your hand before your opponents do the same.

  When it's your turn, try to match the top card on the Discard pile in the center of the table. A Winners page displays when each round is over.

  Match by number, color, or symbol. For example, if the top card is a Red 6, you can play any card from your hand that has a "6" on it, or play any card that is Red.


Draw a Card button

• DRAW CARD. If you don't have any playable cards, you must draw a card from the Draw pile. To do this, click the large, blue button to the left of the Discard pile.

  You can then either play the card you drew (if possible), or press the PASS button to finish your turn without playing a card.

• PASS BUTTON. If y ou don't want to play the card you picked up, press the PASS button to end your turn without playing any card. The PASS button is located in the lower left corner of the table, next to the UNO button.

• UNO BUTTON. As soon as you have only a single card remaining, you must press the UNO button immediately. Failure to do so means you must pick two cards from the DRAW CARD pile. The red UNO button is located in the lower left corner of the table, next to the PASS button.

Special Cards

Just like the actual UNO game, this UNO online card game includes "special" cards in addition to the numbered cards:

Reverse direction of play

• REVERSE. The Reverse card switches the direction of play. The Reverse card has a picture of two arrows facing opposite directions.

  For example, if the next turn belongs to the player on your left, the player on your right takes a turn instead.

• SKIP CARD. The symbol on the Skip card looks like a circle with a slash through it. The Skip card can be any of the four UNO colors.

  The player whose turn is next loses his/her turn when this card is played (they are "skipped"). This card can be played on another Skip card or on any card with a matching color.

• DRAW TWO. When this card is played, the next person to play must draw two cards from the Draw pile. They also miss their turn, and cannot play a card. The Draw Two card has a "+2" on it and a picture of two overlapping cards.

• WILD. This card allows the player who played it to change the current active color. For example, if the top card in the Discard pile is Green, the player can change it to Red, Yellow, or Blue.

  The idea is to change the active color to a color that you have a lot of cards for, or that you know your opponents don't have. The Wild card has a picture of an oval divided equally into the four UNO colors.

• WILD DRAW FOUR. This card not only allows you to change the active color, it also requires the next player to draw four cards.

  The Wild card has a "+4" on it and an oval showing four different UNO color cards.

UNO might not be the most intense brain game ever, but like all card games such as Euchre and Hearts, it does strengthen important brain skills. Enjoy!
