The objective of the game is to get rid of all your cards as quickly as possible. The player who is the first to get rid of all his cards is the winner of the round.
At the beginning of the game, the dealer deals 7 cards to each player, places the remaining pile of cards in the center of the table and turns the first card face up. This card will serve as the starting point.
In turn, each player, starting with the player to the right of the dealer, must place a card on the table that is either the same color, number or symbol as the card currently on top of the pile of cards already placed. Some cards have the privilege of being played at any time, and some cards have special effects, see below.
A player that can't play any of their cards must draw one from the deck (by pressing space). If the drawn card is playable, they can put it down immediately, otherwise their turn is over and it's the next player's turn.
A player who has only one card left in their deck must announce "uno!" to alert the other players (by pressing U). If that player forgot to do this and someone points it out to them (also by pressing U), they must draw 4 penalty cards.
As said above, some cards have a special meaning. Some of them can be played at any time, while others trigger a specific action when played:
When a player puts down this card, the next player skips their turn and the player next to them plays. When only two players are playing, the one who played the card can immediately play again.
When a player puts down this card, the direction of play is reversed. If the game was previously played clockwise, it will now be played counter-clockwise until another reverse card is played. When only two players are playing, the one who played the card can immediately play again.
When a draw two card is played, the next player must draw two cards from the deck before playing.
This card can be put down at any time and allows the player who plays it to choose which color the next player should play.
Wild draw four
This card can be played at any time and requires the next player to draw 4 cards before being able to play. The player who placed it can also choose the next color.
Depending on the variant, the player who has to draw 4 cards may be skipped.
When a player has successfully got rid of all their cards, each player who still has cards in their hand gets points.
Therefore, the winner is the player who has the fewest points after a certain number of rounds or after a certain limit is reached by the loser (often 500, 1000 or 1500 points).
Here is the value of each card in points :
- Ordinary numbered cards are worth the corresponding number from 0 to 9 points.
- The special cards skip, reverse and draw two are worth 20 points
- The special cards wild and wild draw four are worth 50 points
In this variant, the player who has to draw cards after a draw two or wild draw four can, instead of drawing, play another draw two or wild draw four card. The next player must then draw the sum of all the draw cards played, unless that player also has another +2 or +4 card. A draw two can't be placed on top of a wild draw four and vice versa.
If a player puts down a draw two card after drawing their cards, the next player only has to draw 2 cards.
In this variant, whoever has several cards of the same color with consecutive numbers, e.g. yellow 2, 3 and 4, has the right to put them down in the same turn, in ascending or descending order. However, you have to be quick enough, because you lose this right as soon as the next player has played, and the next player has the right to do so as soon as the first card in the sequence has been played.
In this variant, if a player has exactly the same card as the one currently on top of the pile, that player can play it immediately even if it isn't their turn. The player who made the interception can play again, and then play continues to the next player. A number of players may therefore have missed their turn.
IF you aren't fast enough or if you make a mistake, you get 3 penality points... So be careful!
All cards can be intercepted, except wild and draw four cards.
In this variant, all cards can be intercepted as long as they have the same number or symbol, regardless of the color, according to the interception rule above.
In this variant, it is suggested that a wild draw four can only be played if there is no other choice. Putting down a wild draw four when you had the option of playing something else is still allowed, but is considered bluffing (bluffing in the sense of making it look like you had nothing else to play when in fact this is not the case).
The player who has to draw cards following a wild draw four can, instead of drawing, declare that the player who played this card is bluffing. If this is the case, i.e. if the player could have played something else than wild draw four, then the bluffer gets the 4 cards plus two more penalty cards. If, on the other hand, the player suspected of bluffing had no other choice, then the wrongly accusing player must draw two more cards.
This rule is not at all incompatible with the responses rule. In this case, it may be strategically better to wisely draw cards rather than retaliate and risk being caught for bluffing and thus having to draw even more cards in the end.
Skipping turn after drawing cards
This variant proposes the obligation to pass your turn after drawing cards (after a draw two or a wild draw four).
IN this variant, 0 and 7 cards are given special effects:
- When a 0 is played, each player passes their hand to the next player in the current direction of play
- The player who plays a 7 has the possibility, but not the obligation, to exchange their deck with another player of their choice. The player designated for the exchange cannot refuse.
In this variation, we introduce 8 more cards in the deck, the buzzer cards. They can be played at any time and anything can be played on top of them.
When a player plays a buzzer card, all players must press B as quickly as possible, including the one who just played the card. The slowest player will have to draw two penalty cards.
