2	''Uno'' (marketed as ''UNO'') is a CardGame created in 1971 by Merle Robbins and distributed by International Games, Inc. before being bought out by Mattel in 1992.
3
4	The object of ''Uno'' is to accumulate points by ridding all of one’s hand of cards (going out) before anyone else. Each turn, going clockwise from the dealer, the player plays a card onto a discard pile with both cards matching in color, number/symbol, or both. Should the player not have a match, they draw a card. They then have the option of playing the drawn card if it matches the discard pile. When a person plays their second-to-last card, they must announce “[[TitleDrop UNO]]!” or risk getting caught and having to draw two cards. The first player to get rid of all their cards wins the hand and scores points for all the cards held by everyone else. First to 500 points wins.
5
6	Alternatively, the player who goes out does not earn points, and each person counts points for the cards they still hold. First to 500 points loses, with the lowest scoring player winning.
7
8	[[folder:Types of Cards]]
9	* Number Cards (Points based on face value): Numbered 0-9, colored Red, Yellow, Blue, and Green
10	* Action Cards (20 Points)
11	** Skip: Skips the next player.
12	** Reverse: Changes the direction of play. Per former rules, it acts as a Skip card in two-player games.
13	** Draw Two: The next player draws two cards and loses their turn.
14	* [[LiteralWildCard Wild Cards]] (50 Points)
15	** Wild: Can be played anytime. Player declares new color.
16	** Wild Draw Four: Similar to a Wild except it can only be played if the player does not have any cards matching the color of the discard pile (or, per modern rules, a regular Wild). If unchallenged, the next player draws four cards and loses their turn. If challenged (by the next player only), the player shows their cards to the accuser. A successful challenge causes the accused to draw four cards, otherwise an unsuccessful challenge leads to the accuser drawing ''six'' cards.
17	* Wild Extra Cards[[note]]Introduced in the 2016 ''Get Wild for Uno'' version[[/note]] (50 Points, formerly 40)
18	** Wild Customizable: Three Blank Wild cards that can be marked with house rules if desired.
19	** Wild Swap Hands: Player trades hands with one opponent of their choice.
20	** Wild Shuffle Hands[[note]]Replaces the above card in the ''Global Contest Winning Rule'' version[[/note]]: The player collects all cards held by every player (including their own), then shuffles and re-deals them clockwise around the table.
21	[[/folder]]
22
23	The game’s popularity led to an experimentation of games of different genres (stacking, dice, trick-taking, etc.) with most of the original rules intact. The 2000s started a new trend of using the original ''Uno'' deck but having a gimmick to alter gameplay. The list below shows all of the variants produced by International Games and Mattel, and excludes any licensed themes ([[ThemedStockBoardGame which there are too many to list]]).
24
25	[[folder:Cards Only]]
26	* '''''UNO''''':
27	** '''''Get Wild for UNO''''': Adds three Wild Custom cards and a Wild Swap Hands card. Advertised by Mattel as the current basic version.
28	** '''''Global Contest Winning Rule''''': Alternative version of the above where the Wild Swap Hands card is replaced by a Wild Shuffle Hands card. The player who plays the Wild Shuffle Hands card collects everyone's cards, shuffles, and re-deals them clockwise. The new card is based on an official new card rule contest won by Kagami Haruya.
29	** '''''UNO Mod''''': Uses simpler fonts and symbols. Adds a Mod Card where the player chooses a color and then gives one card of that color from their hand to their opponents clockwise until all cards of that color in their hand are gone. It then acts as a normal Wild card to change the color. The games comes in a sliding tray box for easy travel.
30	** '''''UNO Retro''''': Uses the original 1971 design with a new card back.
31	** '''''UNO [=H2O=]/Splash''''': Transparent waterproof cards. Earlier versions include Wild Downpour Cards that make all other players draw one or two cards.
32	** '''''My 1st UNO''''': Card deck reduced to 36; for younger players.
33	** '''''UNO Dare''''': Playing a Dare Card makes the next person do something on a predetermined (or custom) numbered list or draw two cards.
34	*** '''''UNO Dare Adults Only''''': Waterproof cards of the above version. The dare's severity is determined by rolling the Dare Die. Rolling a Reverse makes the previous opponent roll and do the dare instead and vice versa. Rolling a Truth symbol will instead have the player answer a question Truth-or-Dare style.
35	** '''''UNO Colors Rule''''': Special character cards gives the player powers based on the color on the discard pile.
36	** '''''Giant UNO''''': 7.4 × 10.1 inch (18.8 × 25.7 cm) cards.
37	** '''''UNO [=ColorADD=]''''': Colorblind friendly version using [=ColorADD=] symbols.
38	** '''''UNO Flip!''''' (2019): Double-sided cards. Features a light and dark side mechanic, each with different variants of Action Cards.
39	*** '''''UNO Flip! Splash''''': Transparent waterproof cards of the above version.
40	*** '''''UNO Flip! Express''''': Same as below, with Draw 5 cards being replaced with Draw 3s.
41	** '''''UNO Express''''': Card deck reduced to 56 for faster gameplay. The Draw 2 and Wild Draw 4 cards are simplified to Draw 1 and Wild Draw 2. Everyone starts with five cards instead of seven.
42	*** '''''UNO Go!''''': Smaller cards of the above version.
43	** '''''UNO Braille''''': Made with the National Federation of the Blind, all cards have braille labels. A played card must be announced by name, and any player can say "Card Check" to have every other player report the number of cards they have in their hand.
44	** '''''UNO Nonpartisan''''': Red and blue cards (colors representing the U.S. Republican and Democratic parties, respectively) are changed into orange and purple cards. The double-sided Veto Card is placed on the center for anyone to slap at [[BanOnPolitics the player who starts talking politics]]. They are skipped during that turn, and the Veto Card returns back to the center.
45	** '''''UNO Minimalista''''': Symbols, logo, and box are more simplified than ''Uno Mod'' with a black card back. Originally a concept by Warleson Oliveira before being [[AscendedFanfic made official]] due to popular demand.
46	** '''''UNO Nothin' But Paper''''': The original game gone green with everything made entirely with paper, soy-based ink and water-based glue. Features a jungle theme for the cards.
47	** '''''UNO 50th Anniversary''''': A special deck created for the game's [[MilestoneCelebration 50th Anniversary]]. A premium edition featuring a new card and mechanic was released along side it (see below).
48	** '''''UNO Remix!''''': A [[{{Macrogame}} Legacy-styled]] game where a group of players play various rounds using a predetermined set of Remix Cards drawn in order. These cards allow the player to write their name on them for special benefits or drawbacks depending on the card or add tallies to a Draw Card. After all Remix Cards have been used, the game's deck becomes permanent for the group.
49	** '''''UNO All Wild!''''': All number cards are replaced by Wild Cards and all Action Cards have wild properties. Since all cards can be played, the players have to use their Action Cards to skip their opponents, make them draw cards, or swap their hands.
50	** '''''UNO Ultimate''''': A DeckbuildingGame where each [[Creator/MarvelComics Marvel]] or [[Creator/DCComics DC]] character has their own special power and dedicated cards. The player wins by shedding all of their cards from their hand, but they can also lose if their personal draw deck runs out. Aside from the base game, extra characters are sold separately either as an individual box with its own cards or as a foil card that can replace another card from a player's deck.
51	** '''''UNO Party!''''': Card deck increased to 224 for 6-16 players and includes new cards that promote party interaction. The "Jump-in" house rule is implemented as an actual rule known as "Speed Play" to avoid drawn out games.
52	** '''''UNO Flex!''''': Players can apply a one-time flex on their turn to use a number card's secondary color or upgrade basic Action Cards into stronger actions. Players can regain or lose their flex powers by playing flip cards.
53	** '''''UNO House Rules!''''': When a player plays an Add-A-Rule Card (represented by a speech bubble), they make up a rule for that number. Players then must follow that rule every time the associated number is played; the last person to act has to draw a card. A maximum of five rules can be run at once.
54	** '''''UNO Show 'Em No Mercy''''': Card deck increased to 168. The Stacking, Draw-to-Match, No Bluffing, and Seven-O house rules are implemented here. Alongside regular Action Cards, there are stronger cards similar to the ones from ''Uno Flip''. Draw Cards (ranging from +2 to +10) can be stacked as long it has an equal or higher value from the discarded draw. The Mercy Rule eliminates any player who holds more than 25 cards, so a player can also win by being the last one standing.
55	* '''''DOS''''': Sequel to ''Uno'' (see folder below).
56	** '''''DOS Splash''''': Transparent waterproof cards.
57	** '''''DOS Second Edition''''': Updated version which completely revamps the rules and cards to play more like its predecessor.
58	* '''''Wild Twists''''': A standard 52-playing card deck with 8 Wild Cards (two standard, one for red cards, one for black cards, and one of each suit).
59	[[/folder]]
60
61	[[folder:Physical Gimmick]]
62	* '''''UNO Attack/Extreme''''': Instead of drawing cards, players press a button on a machine filled with ''Uno'' cards. The machine can randomly draw up to nine cards, but sometimes it may give nothing. Three versions exist: the 1999 original with eight action cards, the 2010 revision with six action cards, and the 2016 version based on the previous one that includes three Wild Custom Cards and a Hit 4 Wild Card.
63	** '''''Uno Attack Mega Hit''''': Uses a yellow card dispenser. Based on the 2010 revision, ''Mega Hit'' adds a Hit 1 card to the deck. The Mega Hit rule allows Hit 1 and Hit 2 cards to stack on each other, and the player who cannot play a Hit card has to hit the accumulated number of button presses and hopefully not get many cards.
64	* '''''UNO Spin''''': Spin cards (noted by a swirl around the cards corner number) makes the next player spin the wheel instead of playing a card. Some spaces on the wheel have effect on the player who spun it or all players. There's also a small travel version with different wheel spaces.
65	* '''''UNO Reflex''''': The player presses the Reflex button every time a card is played. If it shows a color, then everyone races to discard one of their cards respective of the color. The Reflex machine also dictates the color chosen for a Wild card.
66	* '''''UNO Flip''''' (2009): Players can pass cards to others by playing an Uno Guy Card and successfully flipping the Uno Guy to the target's crash site.
67	* '''''UNO Tippo''''': There are two discard piles on a scale and making one of the sides fall is a two card penalty. Stop and Tilt cards forces players to discard on one scale until a proper card is played.
68	* '''''UNO Blast''''': Whenever a player draws a card, it is then put into one of the machine's discard slots. Choosing the wrong slot causes the discarded cards to jump out, and the player adds the drop cards to their hand.
69	* '''''UNO Flash''''': The machine randomly selects a player to play a card and slap their player button. If they fail to complete their action in time, they suffer a two card penalty. When a Slap card is played, the player's opponents race to slap their buttons with the loser having to draw two cards.
70	* '''''UNO Power Grab''''': Playing a Power card (that have the symbols "U", "N", "O", and "!") allows the player to grab a tower corresponding to the card's symbol. The towers give immunity towards specific cards. Collecting all four is an automatic Uno (discard all but one card).
71	* '''''UNO Roboto''''': The Roboto records the player's names and house rules. Roboto will interrupt play to dictate a special command, a duel, or have the player do a house rule.
72	* '''''UNO Tiki Twist''''': Tiki Cards are placed inside the Tiki Doll Spinner and then spun. The player the Tiki points at after spinning one rotation gets to do the action provided. The card inside the Tiki Doll Spinner is not removed until another Tiki Card is played. Non-Tiki Cards have a spin symbol that forces the one who played it to spin the Tiki Doll Spinner.
73	* '''''UNO Royal Revenge''''': The person who wears the crown dictates the color from a Wild and chooses a player to draw a card from a King Card. The joker is chosen by the king and they always draw a card from the Joker Card. A new king and joker occurs every minute.
74	* '''''UNO Wild Jackpot''''': Playing a Jackpot card lets the player spin the Wild Jackpot. The slot can land on a discard, draw four, or having the player release one of the eight custom rule cards.
75	* '''''UNO Showdown''''': Playing a card with the ◁ # ▷ symbol starts a showdown with the opponent of their choice. In a round, out of the number (#) on the symbol, a card is drawn from the draw pile and put into the unit. Both players have to hit their button the moment the light turns green in which the loser gets the card thrown at them. The player who discards their last card must win their last showdown to win the game.
76	** '''''UNO Showdown Supercharged''''': The same game as above but has a blue electric design and different sound effects.
77	* '''''UNO 50th Anniversary Premium''''': Introduces a 50/50 Wild Card along with a gold coin. Playing the 50/50 Wild Card pits two people in a [[HeadsOrTails coin toss]] where the loser draws four cards.
78	* '''''UNO Triple Play''''': There are three discard piles. However, players may only play on piles that the unit lights up. The discard pile Discard piles have a overload limit, and playing on a discard pile that "overloads" incurs a one to four card penalty, decided by the unit. In a twist, playing a Wild Card ''does not'' let you choose the color that continues play; rather, the next player chooses it by playing any card onto it. Wild Clears allow the user to reset the "overload" limit and Wild Give Aways, if played on an overloaded discard pile, allows the user to give their cards they would otherwise get to other players.
79	** '''''UNO Triple Play Stealth''''': Besides a darker coloration, this version adds a Stealth mode where the overload limit warnings are not shown to the players.

82	[[folder:Digital Only]]
83	* ''UNO Free Fall'' (2006): [[FallingBlocks Falling block]], [[MatchThreeGame match three game]]. Matches are three or more connecting pieces either by color or number.
84	* ''UNO 52'' (2006): Poker mixed with Uno. Game plays just like the original, except discarding a card from your hand to the discard allows one to place another card into their Poker Hand (also using ''Uno'' rules). The player who goes out wins a blue chip (10 pts.) and the player with the best hand wins a red chip (5 pts.). Winning both chips in a round also receives the entire white chip pot as a bonus. The 52 card deck comes in four colors, raising the total deck to ''240''.

102
103	[[folder:''DOS'']]
104	After 47 years, a sequel by the name of ''Dos'' (marketed as ''DOS'') was announced on February 2018 and released on March 4, 2018[[note]]Timed exclusive on Target; August 2018 for other stores[[/note]]. It features a different set of rules:
105
106	* Matching:
107	** Cards must match only the number of one of the two available center piles.
108	** A player can use two cards at once (a double match) adding up to a center pile's number (e.g. a 3 and a 4 on top of a 7).
109	** All center piles can be played on, but only one match per pile is allowed. For example, should there be two center piles present, one can be single matched and the other double matched or both piles be double matched.
110	* Ending Turns:
111	** Every center pile that has been played on is moved to a separate discard pile. If there are less than two center piles, then it is refilled back to two using the Draw deck.
112	** Cards from color matches are then added to the center pile.
113	* Color Bonuses:
114	** If a single match has the same color as the center pile being played on, the player adds a card from their hand onto the center pile.
115	** If a double match both have the same color as the center pile being played on, all opponents draw one card and the player adds a card from their hand onto the center pile.
116	* Other Tidbits:
117	** When no match is available, then the player draws a card and plays it if its valid. If it's not, then they place a card from their hand to the center row. This can be done even when the player has valid cards on their hand.
118	** The Action cards of the first game are replaced by the new Wild Color Dos (2) card and a Wild Number (#) card. These are worth 20 and 40 points respectively at the end of a round.
119	** The player shouts "DOS!" when down to two cards left. Failure to do so and getting caught before the next player's turn starts is a two card penalty.
120	** The player who goes out adds up all of the opponents' cards by face value. First to 200 points wins.
121
122	In 2023, an updated version known as the ''Second Edition'' completely changes the rules to play more like its predecessor:
123
124	* Playing Cards:
125	** There are only two discard piles, and layed discard piles are not replaced.
126	** Players can play cards on one or both discard piles, matching either number, symbol, or color.
127	** Two cards of the same color ''can'' be played on one pile if it equals that number (e.g. a green 3 and green 4 on a red 7).
128	** There are no color match bonuses.
129
130	* Action Cards:
131	** The Wild Number Card from the first edition is replaced by the returning Skip, Reverse, and Draw 2 Cards.
132	** If the player plays two Action cards, both affect only the next player in order.
133	** The Wild DOS Card works as both a "2" and a Wild Card.
134	** The Wild Play Two Card allows choosing the color of the discard pile and forces the next player to play two cards. If unable, then they'll draw two cards.
135
136	The goal has been increased to 500 points.
137	[[/folder]]
138
139	There is also a [[LetsPlay/UnoTheMovie fan film]] by Creator/RoosterTeeth's Creator/AchievementHunter where the players play the video game version on the highest settings and every house rule turned on with [[ThisIsGoingToSuck terrible results]]. They followed it up years later with [[LetsPlay/UnoInfinite a live stream of them playing the physical game]] with the same house rules as their previous video, with a few new unique ones that led to their hands becoming ''decks'' of cards. It lasted for ''[[SerialEscalation thirty-seven-and-a-half hours]]''.
140
141	!!''Uno'' provides examples of:
142	* SixIsNine: Defied. The 6 and 9 cards have underlines below them so that players don't confuse them with each other.
143	* [[ActionizedSequel Actionized Spin-Off]]: ''Uno Attack/Extreme'' amps up the ante by making players press a button on a machine to draw cards. The Wild All Hit card requires everyone to hit the button once while the Wild Hit Fire forces the next player to hit the button until the machine draws the cards. Sometimes it may give nothing, yet other times the machine will loudly shoot at you a random amount of cards (up to 9). The 2010 revision downplays the action by changing the two Wild cards into simply choosing a player to hit the button twice. ''Uno Attack Mega Hit'' raises it back up by allowing Hit cards to stack up and force an unlucky player to hit ''all'' of the accumulated number of button presses.
144	* AdvertisingByAssociation: Other published card games by International Games and Mattel (such as ''Phase 10'', ''Boom-o'', ''Skip-Bo'', etc.) have a insert on the box proclaiming it came "From the TabletopGame/MakersOfUno".
145	* AprilFoolsDay: In 2011, Mattel [[https://www.facebook.com/uno/photos/a.147458915311232.29451.120101848046939/162050663852057/?type=3&theater announced a sequel by the name "Dos"]], featuring a deck of only two numbers (two and four) and two colors (blue and green). Nearly six years later, an actual sequel named ''Dos'' is produced, albeit with different rules and a more variable deck.
146	* ArtificialStupidity: The AI in the Ubisoft game tends to do some ''unusual'' plays. Most notably, they'll play a Wild Card only to 'change' the color to the current color already on the discard pile.
147	* BilingualBonus:
148	** Uno and Dos are Spanish for One and Two, respectively.
149	** Quatro in ''Uno Quatro'' is actually Portuguese for Four.
150	* ColourCodedForYourConvenience:
151	** ''Uno'' boxes and cards are colored red (with an oval) while ''Dos'' cards are colored blue (with a circle).
152	** Wild cards are colored black to signify these can be used on any color.
153	* ComebackMechanic:
154	** The ''Uno Spin'' wheel has a space called "Almost Uno", which when landed allows the player to keep two of their cards (of their choice) and discard the rest.
155	** In ''Uno Power Grab'', if you somehow have all four Power Towers (which altogether spell out "UNO!"), you can surrender the towers to discard all but one card.
156	** Color matching in ''Dos'' lets the player remove more cards from their hand. However, the increased number of cards in the center pile gives the next player more options to play their cards.
157	* CompressedAdaptation: ''My 1st Uno'' and ''Uno Express'' have reduced card decks. Each player starts with five cards rather than seven.
158	* CounterAttack: Challenging a player of an illegal Wild Draw Four.
159	* {{Crossover}}: Downloadable content for the Creator/{{Ubisoft}} game has this with other Ubisoft-owned properties, such as ''Rabbids'', ''Just Dance 2017'' and ''Rayman'', several of which have their own unique cards to twist the formula of a traditional game.
160	* DarkWorld: The main gimmick of ''Uno Flip!'' (2019) is literally flipping between the Light Side and the Dark Side of the cards on your hand, the Discard Pile, and the Draw Pile as all of the cards are double-sided. The Dark Side has its own set of colors (pink, orange, teal and purple) and far meaner cards than the Light Side such as a Draw 5 card, Skip Everyone card (effectively an ExtraTurn), and a Wild Draw Color card (the target keeps drawing cards until the chosen color shows up; picking a Wild does NOT count).
161	* DexterityGame: ''UNO Stacko'' features a tower of blocks where you try to remove one and put it on top without making the whole tower fall over, but now the blocks have colours and numbers affecting which determine what blocks you'll be pulling out. There are also a few blocks with special effects on the game.
162	* DigitalTabletopGameAdaptation: ''Uno'' has an app for iOS and Android. It also had a Facebook Games application.
163	* DrawExtraCards: The Draw Two, Draw Four, and Wild Draw Four cards, which forces the opponent to draw cards, putting them at a disadvantage as the goal of the game is for a player to empty their hand of all cards.
164	* EarlyInstallmentWeirdness: The original ''Uno'' deck had heavy shadows on the symbols, the background shape was a rounded rhombus than an oval, and the Action cards were written out and its corresponding symbols were letters (e.g. S for Skip). The ''Uno'' logo was originally colored red with a white rim.
165	* ExtraTurn:
166	** Skips and Draw Cards skip the next player.
167	** Creating a color match in ''Dos'' grants the player to discard an additional card from their hand to the Center Pile. This is not limited, so two color matches equals two extra discards.
168	** The Skip Everyone cards in ''Uno Flip!'' (2019).
169	* FakeLongevity: Reaching 500 points in ''Uno'' takes a long time to reach since players tend to discard the higher valued Action Cards. It gets even worse with just two players. This is why some house rules either lower the amount or drop the points goal altogether. ''Dos'' lowers the amount to 200 points.
170	* GivingSomeoneThePointerFinger: The Point Taken card in ''Uno Party'', represented by a pointing hand, has everyone point at one of their opponents. Players then draw cards depending on the number of fingers pointed at them, up to a maximum of 5 cards.
171	* HeadsOrTails: The ''50th Anniversary Premium'' edition adds a gold coin along with matching Wild 50/50 Cards. Playing a Wild 50/50 allows the player to pit two people in a coin toss with the gold coin with the loser drawing 4 cards along with changing the current color of play.
172	* JuniorVariant: ''Uno Junior'' has slightly lighter rules for children to learn and a smaller deck so that cards are less likely to be lost.
173	* KickThemWhileTheyAreDown: If the last discarded card in one's hand is a Draw card, the next player draws that many cards before ending the round. This adds bonus points to the winner (or the loser if playing with the alternative rules). The same applies for ''Dos'' for any double color match bonuses created in the winning turn.
174	* LaterInstallmentWeirdness: Coming from the multitude of ''Uno'' spin-offs and variants, cards in ''Dos'' can only match by number with color being a bonus. The sequel lacks any attacking cards; the only way for others to draw cards (and even then only one card) is to make the uncommon double color match. Also rounds go by much faster than ''Uno'' due to the multiple center piles and the color match benefits allowing to discard many cards at once rather than just one per turn.
175	* LevelEditor: ''Get Wild for Uno'', ''Uno Wild Jackpot'' and many themed versions have erasable blank cards for adding new rules. The Swap Hands Wild card for the former game provides a physical example (the symbol has a pencil-drawn look).
176	* LiteralWildCard: On the holder's turn, a wild card may be played on any card, whereafter the person who laid it chooses which color continues play. The draw four card is a more powerful wild as it also requires the next player to draw four cards and skip their turn, but may be played if they have no matching color or as a bluff--the next player may attempt to challenge said card.
177	* TheMoralSubstitute: The game is popular in religious communities with objections to standard playing cards because of the neutral imagery.
178	* NonSequitur: Some versions, such as ''Uno Dare! (Adults Only)'' and ''Uno Roboto'', may have players do tasks that have nothing to do with the game, such as doing a runaway model walk, acting like a cat or balancing a card on the head. ''Uno House Rules!'' encourages making tasks in this fashion, with the last player to complete the agreed upon action drawing one card.
179	* NumberedSequels: PlayedWith. The sequel to ''Uno'' (One) is named ''Dos'' (Two). ''Uno'' retroactively becomes a Title1 name.
180	* OddlyNamedSequel2ElectricBoogaloo: The Japanese-only Game Boy game ''[[https://www.youtube.com/watch?v=brI0dT5bSmQ Uno 2: Small World]]'' (if going on how the boxart and title screen are presented, as its predecessor is titled ''Uno: [[RecycledTitle Small World]]''). There's no changes to the ''Uno'' formula nor does it add any game modes.
181	* OfficialGameVariant: Mattel once held a contest to see what house rules people used, and chose the following three to be added as official variants:
182	** ''Jump-in Uno'': If you have the exact same card as the top of the discard pile, you may play it immediately, even if it isn't your turn. Play resumes from the player who "jumped in".
183	** ''Seven-O Uno'': Like regular Uno, except that playing a 0 forces every player to pass their hand to the next player in the direction of play, and that playing a seven forces you to trade your hand with a player of your choice.
184	** ''Progressive Uno'': Allows Draw Two and Draw Four cards to be stacked on top of cards of the same type, but does not let you stack Draw Twos on Draw Fours, or vice versa.
185	* OnThree: Whoever plays a Point Taken card in ''Uno Party'' counts out loud from three. Then, on one, each player points at another.
186	* {{Retraux}}: The ''40th Anniversary Edition'' and ''Retro'' decks uses the 1971 design, with the latter deck using a different card back.
187	* SecondPlaceIsForWinners: PlayedForLaughs in ''Dos'''s packaging proclaiming itself as the "The World's #2 Card Game"... clarified as an "Unverified Statistic". This seems to be removed in current prints though.
188	* SelfDamagingAttackBackfire: If playing a Draw card in ''Uno Flash'', and the light that comes up is ''your own''.
189	* {{Synchronization}}: The Wild Drawn Together card in ''Uno Party'' makes a player link two different opponents. When a linked player draws cards, the other does too by the same amount. The players become unlinked when a Point Taken or another Wild Drawn Together card is played.
190	* ThemedStockBoardGame: ''Many'' licensed themes. Some differ from others by the inclusion of exclusive cards such as a Draw 3 or looking at another person's hand.
191	* TitleScream:
192	** Anytime you're down to one card. Or two cards when playing ''Dos''.
193	** In ''Uno Spin'', when the wheel lands on the Uno Spin space, the first player to shout the title gets to discard a card.
194	** In ''Uno Bingo'', you win by getting three-in-a-row on your card and then saying the title.
195	** In ''Uno Madness'', you say "Madness" after ''every single move''.
196	* TotallyRadical: For the game's 50th anniversary, five new decks were released--one for each decade the game's been around. The descriptions on the back of the box each read like a marketing executive is trying to come off as hip to the youth of that decade (for example, the 90s one references ''Series/BeverlyHills90210'' and tells the player to "get jiggy with it").
197	* TransAtlanticEquivalent: The Israeli game ''Taki'' (''Super Taki'' in other regions). Gameplay is the same as ''Uno'', but ''Taki'' emphasizes on speed as it has cards that allow a player to discard multiple cards at once. Draw 2s can be stacked, and Draw 3s can be reflected back to the user by the use of a Draw 3 Breaker card.
198	* UnexpectedGameplayChange:
199	** [[DownplayedTrope Downplayed]]. Unlike in previous ''Uno'' iterations, playing a Wild Card in ''Uno Triple Play'' does ''not'' let you change the color of your choice. Instead, the next player in turn decides what the next color in play is by playing a card.
200	** The Wild Pile Up card in ''Uno Party'' temporarily pauses a match to play a condensed version of ''Uno'' from a separate discard pile where only the color can be matched. Wild and Action cards can be played but do not take effect. The person who lacks a playable card picks up the discard pile and places it on their hand. The player who played the Wild Pile Up does not choose a color; the color drawn to start the pile up is the color decided.
