Uno online is the digital adaptation of the classic card game Uno, originally developed by Merle Robbins in 1971 and now owned by Mattel. Just like the physical game, the online version revolves around matching cards by color or number, using action cards to disrupt opponents, and being the first to score points by emptying your hand.

The uno online version allows players to enjoy Uno anytime, anywhere, with friends, family, or even strangers around the world. With various game modes, themes, and tournaments, Uno online has gained a massive following among casual and competitive gamers alike.

How to Play Uno Online
Objective of the Game
The main goal in Uno online is to be the first player to score 500 points (or the point target set by the game). Points are earned by being the first to empty your hand and collecting the value of cards left in your opponents' hands.

Basic Rules
Starting the Game: Each player is dealt seven cards. The rest form the draw pile, with the top card placed face-up to start the discard pile.
Playing Cards: On your turn, match a card from your hand with the color or number of the top card on the discard pile.
Special Cards:
Skip: Skips the next player's turn.
Reverse: Reverses the order of play.
Draw Two: Forces the next player to draw two cards.
Wild: Lets you choose the color of play.
Wild Draw Four: Lets you choose the color and forces the next player to draw four cards (can only be played if you have no matching cards in your hand).
Uno Call: When you have one card left, you must press the "Uno" button. Failing to do so before your turn ends can result in drawing penalty cards.
Winning a Round: The round ends when a player discards their last card. Points are calculated based on the cards remaining in other players' hands.
