How to Play Uno:

1. Uno is a card game played with a special deck of cards.
2. Each player is dealt a hand of cards, and the remaining cards form a draw pile.
3. The top card of the draw pile is placed face up to start the discard pile.
4. Players take turns matching the top card of the discard pile by color, number, or action.
5. If a player cannot match the top card, they must draw a card from the draw pile. If the drawn card can be played, they may play it immediately.
6. Special action cards have different effects, such as skipping a player's turn, reversing the direction of play, or forcing the next player to draw cards.
7. The first player to empty their hand wins the round, and points are scored based on the value of the cards remaining in other players' hands.
