Click the green flag to start the game. Three purple buttons with 2P, 3P, and 4P on it will appear. For a 2-player game (1 opponent), click the purple 2P button. For a 3-player game (2 opponents), click the purple 3P button. For a 4-player game (3 opponents), click the purple 4P button. You'll start with 0 points and 3 lives. The game will deal 5 cards to each player. On your turn, click on one of your cards to play it if it has the same color, number, or symbol as the top card of the discard pile. If you cannot play a card or if you choose not to, click the draw pile to draw 1 card and end your turn. You cannot play the drawn card immediately on that turn, even if it is playable. After you play a card or draw, the next player in the current turn order takes their turn. The first player to play all of their cards wins the round. If you win the round, you'll score points based on the sum of the point values of the cards remaining in the opponents' hands. See the Notes and Credits section for more information on this. If your opponent wins the round, you'll lose 1 of your lives. If all 3 lives are lost, the game ends. Click the cyan Next button to start the next round. Lives that are lost cannot be recovered, so be careful!
In the first round, you'll always go first. But in the second round and onwards, the winner of the previous round goes first. If the card flipped to start the discard pile isn't a number card, the game will flip another card until a number card (0 through 9) is flipped. If you have too many cards in your hand, you can click the yellow Left and Right buttons to scroll. When you play a card with a special symbol on it, one of the following actions will be triggered depending on what the symbol on that card is. Skip (a card with a circle with a diagonal line in it): The next player loses a turn and the player after them in the current turn order goes next. In a two-player game, the player who played this card takes another turn. Reverse (a card with a pair of arrows pointing in opposite directions): The turn order changes from clockwise to counterclockwise and vice versa. The arrow to the right of the discard pile will flip to indicate this. In a two-player game, it has the same effects of a Skip card, so the player who played this card takes another turn. Draw 2 (a card with "+2" written on the upper left and lower right corners with two colored cards on the center): The next player draws 2 cards and skips their turn unless they can play another Draw 2 card regardless of color. If they do, the player after them in the current turn order draws 4 cards unless they can play a third Draw 2 card which forces the player after them to draw 6 cards unless they can play a fourth Draw 2 card, and so on until the cards are finally drawn. Wild (a card with a circle showing all four colors): This card can be played anytime on your turn unless the player before you discarded a Draw 2 card or a Wild Draw 4 card. When played, you can change the current color to any color of your choice. Click on one of the four colored buttons that appear above the deck and the discard pile that corresponds to your choice to change the current color to that color. Wild Draw 4 (a card with "+4" written on the upper left and lower right corners with four cards showing all four colors on the center): This card can be played anytime on your turn unless the player before you discarded a Draw 2 card. When played, you can change the current color (see the explanation of the Wild card for how to change the current color) and the next player draws 4 cards unless they can play another Wild Draw 4 card. Like with Draw 2 cards, its effects can be stacked by multiple players in turn order. If you win the round, you'll score points for your opponents' cards as follows. Number cards (0 through 9): Face value (A number 4 card is worth 4 points, and so on.) Skip cards: 20 points each Reverse cards: 20 points each Draw 2 cards: 20 points each Wild cards: 50 points each Wild Draw 4 cards: 50 points each The deck includes 108 cards as follows. 19 Blue cards (one card numbered 0 and two of each card numbered 1 through 9) 19 Red cards (one card numbered 0 and two of each card numbered 1 through 9) 19 Green cards (one card numbered 0 and two of each card numbered 1 through 9) 19 Yellow cards (one card numbered 0 and two of each card numbered 1 through 9) 8 Skip cards (two in each color) 8 Reverse cards (two in each color) 8 Draw 2 cards (two in each color) 4 Wild cards 4 Wild Draw 4 cards
