On February 13, 2018, Mattel released a spin-off of Uno entitled Dos; the game is differentiated primarily by having a "center row" of discard piles, where pairs of cards that add up to the sum of a card on the top of one of the piles may be discarded. [18] [19] [20] Once a player has no cards remaining, the game round is over, points are scored, and the game begins over again. Normally, everyone tries to be the first one to achieve 500 points, but you can also choose whatever points number to win the game, as long as everyone agrees to it. Modern Uno action cards bear symbols which denote their action, except for the Wild cards which still bear the word "Wild". Before the design change, such cards in English versions of the game had letters only. Earlier English versions can be recognized by the absence of the white rim that surrounds the edge of most Uno cards. A player may play a Wild Draw Four card only when that player has no cards matching the current color. The player may have cards of a different color matching the current number or symbol or a Wild card and still play the Wild Draw Four card. [6] A player who plays a Wild Draw Four may be challenged by the next player in sequence (see Penalties) to prove that their hand meets this condition. If not otherwise challenged, an illegally played Wild Draw Four stays without penalty for its player. Open source and extensible software - The Arduino software is published as open source tools, available for extension by experienced programmers. The language can be expanded through C++ libraries, and people wanting to understand the technical details can make the leap from Arduino to the AVR C programming language on which it's based. Similarly, you can add AVR-C code directly into your Arduino programs if you want to.

Lyons, Margaret (March 26, 2013). "Who Doesn't Want an UNO TV Show?". Vulture . Retrieved March 26, 2013. Wild – This card represents all four colors, and can be placed on any card. The player has to state which color it will represent for the next player. It can be played regardless of whether another card is available. If turned up at the beginning of play, the first player chooses what color to continue play. Jump-In: If a player has exactly the same card (both number and color) as the top card of the discard pile, they may play it immediately, even if it is not their turn. Play then continues as if that player had just taken their turn. [6] See the getting started guide.

Over the years, it's grown to become one of the most recognizable card games. There are now 100s of themed variations of the game based on anything from football to movies, some with slightly different rules and special cards. Every time a Wild or Wild Draw Four card is played, whoever played it must declare the new matching color before ending their turn. Note: If the first card turned up from the Draw Pile (to form the Discard Pile) is an Action card, the Action from that card applies and must be carried out by the first player (as stated, it is usually the player to the dealer’s left). The exceptions are if a Wild or Wild Draw Four card is turned up. UNO! - The Classic Multiplayer Party Card Game!
