**Background:**
UNO was created by Merle Robbins in 1971 and is now owned by Mattel. The online version of UNO was launched in 2009. In 2022, a multiplayer upgrade was introduced, enabling players to compete in real-time against opponents worldwide.

**How to Play:**
Each player draws a card to determine who will be the dealer, typically the one with the most points. Players are dealt 7 cards each, and the remaining cards form the draw pile. The top card from the draw pile is turned face-up to start the discard pile—if it’s a Wild or Wild Draw 4 card, draw a new card. Players take turns matching the top card of the discard pile by color or number, drawing cards as needed until they have a playable card.

Gameplay online is similar to the physical game but offers added convenience and the ability to play with anyone globally. Use various tactics to improve your chances of winning, such as strategically playing special cards. The main goal remains to discard all your cards before your opponents do.

When you have only one card left, press the “UNO” button to avoid penalty cards. The first player to run out of cards wins the game.
