To win the game, you need to clear all the cards from your hand by matching them to the top card of the pile based on either color or number. In the online version of Uno, your main objective is to be the first player to get rid of all your cards. The game can be enjoyed by 2 to 4 players, whether friends or random opponents online. Use strategic moves and special cards to block your rivals and gain an advantage. When you have only one card left, don’t forget to shout “UNO” using the designated button; failing to do so will result in two penalty cards.

Uno is a classic favorite among card gamers worldwide. Though simple to learn, it offers enough strategy to keep players engaged.

**Background:**
Uno was created by Merle Robbins in 1971 and is now owned by Mattel. The digital version, Uno Online, was launched in 2009, and multiplayer features were introduced in 2022, allowing real-time gameplay against actual opponents.

**How to Play:**
Each player is dealt 7 cards. The remaining cards form the draw pile, with one card turned face-up to start the discard pile. If the top card is a Wild or Wild Draw 4, replace it with a new card from the draw pile. Players take turns matching their cards to the top card on the discard pile by either color or number. If a player cannot make a match, they draw cards from the pile until they find a playable one. During their turn, players can use special cards to hinder opponents or change the game’s course.

**Online Play Adjustments:**
While the core mechanics remain the same, playing Uno online offers added convenience and the chance to play with anyone worldwide. Employ various strategies to maximize your chances of winning—mainly by playing your cards before others do.
