How Uno Works

UNO Attack and DOS

Once you've mastered the intricacies of the original UNO game, look at Mattel's UNO Attack, aka UNO Extreme. This version features an electronic card shooter that shoots out a random number of cards whenever a player has to draw. At the press of a button, it shoots out up to 10-12 cards at the players. The electric card shooter adds an element of surprise to a game that's already fast-paced and challenging.

UNO Attack rules resemble the original game's, but with a few different command cards. Instead of a Wild Draw Four card, there's a card called "Wild Hit Fire." When it's played, the next player has to hit the launch button. Since there's no draw pile, a player must hit the launch button whenever he or she must draw. As a result, you never know when a stream of cards will come flying your way.

As in the original version, players must say "Uno!" as soon as they play their next-to-last card. If the player forgets to do so and another player notices, the poor forgetful soul must press the button — and possibly add up to 10 cards to his or her hand.

Uno Attack uses 112 cards, including the colored number cards, the aforementioned Reverse, Skip, Wild and Draw Two cards, plus the addition of the "Wild Hit Fire" card.

The electronic card shooter gives this popular game a great twist. As the game's tagline says, it's a random, rapid-fire card shoot-out!

In 2018, UNO got a buddy named DOS, the goal of which is the same: shed your cards as fast as possible, gleefully yelling "DOS" when you have two cards left. The game's designed for two to four players. It uses two piles, with each player starting off with seven cards, same as UNO, and matching to the center two piles by number. For example, you can play a blue 4 on a yellow 4 (a single match). You could also play a 3 card and a 1 card of any color on that 4, because 3 and 1 add up to 4, right? That's a double match.

Once you make a match on one or both piles, the player moves that stack of cards to the discard pile. You can also earn a bonus for matching by color and number, the bonus being you get to ditch another card at the end of your turn. If you do a double match by color and number (e.g., using a yellow 3 and yellow 1 to match a yellow 4), you get to ditch a card and make your fellow players draw one. Scoring's pretty much like it is for UNO. Confused? Don't be. You'll get the hang of it soon. Mattel also made a short video explaining the rules that helps a bunch, too.
