Uno is an electronic adaptation of the classic card game. It can be played locally against AI opponents or in multiplayer locally or online. The classic rules are carried over as the first player of four participants to play all cards and empty the hand, wins the game. Also incorporated is a button to call "Uno" when down to a last card. Other players can challenge this if a player forgets to call it, forcing that player to draw two extra cards. Optional rules are Jump-In which allows a player to play a card out of turn to match a card that is played if it is completely identical (usually both number and colour). Playing a 7 allows that player to swap hands with any other player. Stacking allows players to stack penalties by playing the same type of card when Draw Two or Wild Draw Four is played, moving it on to the next player. These rules, along with some basic ones such as Force Play (a drawn card that can be played is played automatically), Draw-to-Match (drawing is continued until a card can be played instead of just one draw) and No Bluffing, can be disabled individually. It is also possible to set a score limit. Single-player games can be played as solo matches or two-versus-two (partnering with a real player or the AI). In a cooperative game the cards of the two members are shown at all times so it is possible to provide help. For new players there is an interactive tutorial. Multiplayer supports a video chat so players can see each other. The base game can be expanded with DLC to add theme cards and new powers. These are based on other Ubisoft franchises such as Rayman or Just Dance. The game supports leaderboards, online lobbies and the overal results are tracked. A Rabbids theme is included right away.
