If anyone draws an action card without a number, it counts as a 0.

If you reveal a Wild card when you flip the top card over, then the player to your left gets to choose the starting color.

On the Light Side, the colors are blue, green, red, and yellow. On the Dark Side, the colors are pink, teal, orange, and purple. The numbers on the cards range from 1 to 9 in each color. You can play a Wild card no matter what the top card of the discard pile is. Always try to play a card from your hand if you can since you earn points for playing all of your cards.

If the draw deck runs out of cards during a round, just shuffle the discard pile to make a new draw pile.

If you forget to say “UNO!” before the next player starts their turn, another player can catch you by saying something like, “You forgot to say UNO!” If you get caught, you have to draw 2 cards from the top of the deck right away.

Cards with the numbers 1–9 are worth their face value in points. Draw One: 10 points. Draw Five: 20 points. Reverse: 20 points. Skip: 20 points. Flip: 20 points. Skip Everyone: 30 points. Wild: 40 points. Wild Draw Two: 50 points. Wild Draw Color: 60 points.

Fun variation: Instead of awarding points to the first player out each round, players add the points left in their hand after each round to their score. Once a player reaches 500 points, the player with the least amount of points wins.

If this is the first Flip card played in the game, you’ll change from the Light Side to the Dark Side. There are 2 Flip cards of each color in both the Light Side and Dark Side of the deck. Dark Side action cards are more powerful than Light Side actions.

There are 2 Skip Everyone cards of each color in the Dark Side of the deck.

There are 4 Wild Draw Two cards in the Light Side of the deck. If another player thinks you have another card in your hand that you were able to play, they can challenge you to reveal your hand.

There are 4 Wild Draw Color cards in the Dark Side of the deck. If someone thinks you had a card of the same color as the discard, they can challenge you to reveal your hand.
