If you can’t decide who should be the dealer, have everyone pick a card, and whoever has the highest number on it gets to deal. (Special cards count as 0 for this purpose. )[2] X Research source
For example, if the card on top of the discard pile is a blue 3, you can discard a 3 of any color, or a blue of any number or word.
If there are some cards sticking halfway out of the launcher, you have to take all of those too!
Reverse: reverses direction of play. Skip: skips the next player’s turn. Hit 2: You have to hit the Launcher button twice. Trade Hands: Trade your hand with a player of your choosing. Discard All: This card lets you discard all the cards of the same color as the last card on the discard pile. Wild Card: can be played on any card. The person who played it gets to decide the color going forward. Wild All Hit: The person who played it calls a color, and then everyone has to hit the Launcher button except the player who played Wild All Hit. The play continues with the color the player called. Wild Hit-Fire: The person who played it calls a color, and the person after them presses the launcher button until it launches cards. Then they take all the cards and lose their turn.
You can’t catch a player for not saying UNO after the next player begins their turn, so pay close attention to your fellow players’ hands.
Younger players will appreciate having a winner after every round, instead of the more complicated scoring system if you extend the game.
Numbered cards are counted by their face value, Reverse/Skip/Hit 2 are 20 points, Discard All/Trade Hands are 30 points, and all Wild cards are 50 points. [10] X Research source
