OONO Plus is a game designed for 2-4 players, with the objective of being the first player to get rid of all the cards in their hand.

Cards and Distribution

The game uses a complete set of OONO cards (108 cards) divided as follows:

- Number Cards: The game includes number cards (0-9) in different colors: red, yellow, blue, and green.

- Action Cards: These cards come in various colors and have different effects. They include:

- Reverse Card: Changes the direction of play from clockwise to counterclockwise or vice versa. In a two-player game, it skips the opponent's turn.

- Draw 2 Card: Forces the next player to draw two cards from the deck. If the next player has a Draw 2 card, they can play it, forcing the subsequent player to draw four cards or skip their turn.

- Skip Card: Skips the next player's turn. In a two-player game, it skips the opponent's turn.

- Wild Card: Allows the player to choose the color that the next player must play.

- Wild Draw 4 Card: Allows the player to choose the color the next player must play and forces them to draw four cards. If the next player has a Wild Draw 4 card, they can play it, forcing the subsequent player to draw eight cards or skip their turn.

As for the distribution, the dealer is chosen randomly, and each player is dealt seven cards. The remaining cards are placed face-down to form the draw pile. The top card from the draw pile is placed face-up to start the discard pile.

How to Play

The player sitting to the left of the dealer starts by throwing any card into the fire, provided that this card:

- Matches the color of the last card of any value.

- Matches the value of the last card of any color.

The turn passes between players clockwise, and if any player does not have a card that matches the color or value of the last card in the fire, they must draw from the deck.

OONO

OONO is the word a player says when they have two cards left and choose to play one, placing it in the discard pile. Here, the player must say OONO to warn the other players before playing their second-to-last card. If a player fails to announce OONO and is caught by the other players, they are penalized by drawing two cards from the deck. This situation is known as the "OONO Challenge”.

Scoring

The player who finishes their cards first is the winner of the round and earns 0 points. Points are calculated based on the remaining cards in the hands of the other players. The lower the total points a player has, the higher their rank at the end of the round.

Points are scored in OONO as follows:


- Number cards = the value of the card itself.

- Draw two = 20 points.

- Skip card = 20 points.

- Reverse card = 20 points.

- Wild Card = 50 points.

- Draw four = 50 points.
