UNO

To set up the game, each player draws a single card from the deck. The player with the highest card value becomes the dealer. Any card with a symbol on it is considered to have a value of zero for this initial draw. The dealer then shuffles the entire deck and deals 7 cards face down to each player. The remaining cards are placed face down in the center of the playing area to form the draw pile. The top card of the draw pile is then turned face up and placed next to it, starting the discard pile. If the first card turned up is a special action card, specific rules apply as detailed in the 'Turn' section.

The main objective in UNO is twofold: in each round, you aim to be the first player to successfully play all the cards from your hand. When a player empties their hand, they score points based on the cards remaining in their opponents' hands. The ultimate goal is to be the first player to accumulate a total of 500 points over multiple rounds, which declares you the winner of the game. Alternatively, players can agree to play until the draw pile is exhausted, and the player with the lowest score wins.

When it's your turn, you must play a card from your hand that matches the top card of the discard pile. This match can be by number, color, or symbol. For example, if the top card is a red 7, you can play any red card or any color 7. If you have no matching card, you must draw one card from the draw pile. If the drawn card matches, you can play it immediately; otherwise, it's added to your hand, and your turn ends. Special action cards have unique effects: 'Draw Two' forces the next player to draw two cards and skip their turn; 'Reverse' changes the direction of play; 'Skip' skips the next player's turn; 'Wild' allows you to choose the next color to be played; 'Wild Draw Four' allows you to choose the next color and forces the next player to draw four cards and skip their turn (this card can only be played if you have no other card in your hand that matches the current color on the discard pile). If a 'Draw Two' or 'Reverse' card is the first card turned up at the start of the game, the first player (or dealer for 'Reverse') must draw two cards or the direction of play is reversed, respectively. If a 'Skip' card is turned up, the player to the dealer's left is skipped. If a 'Wild' card is turned up, the player to the dealer's left chooses the starting color. If a 'Wild Draw Four' is turned up at the start, it is returned to the deck and another card is drawn.

At the end of each round, once a player has successfully played all their cards, points are tallied. The player who went out receives points for all the cards remaining in their opponents' hands. Number cards (0-9) are worth their face value. 'Draw Two', 'Reverse', and 'Skip' cards are each worth 20 points. 'Wild' cards and 'Wild Draw Four' cards are each worth 50 points. 'Wild Shuffle Hands' and 'Customizable Wild' cards are each worth 40 points. These points are added to the score of the player who finished the round, and play continues to the next round until a player reaches the target score.

The game concludes when one player accumulates a total of 500 points across multiple rounds. That player is then declared the winner. An alternative way to end the game, if agreed upon by players beforehand, is to play a predetermined number of rounds. In this scenario, the player with the lowest total score at the end of the final round is declared the winner. If the draw pile runs out during a round and no player has emptied their hand, the discard pile is shuffled to create a new draw pile, and play continues.
