Uno Flip!

As in the original Uno, the goal of Uno Flip! is to be the first to play all the cards in one's hand, scoring points for the cards still held by others.

All cards are two-sided, consisting of the "Mild" side (also known as the "Light" side) with white fonts and borders and the "Wild" side (also known as the "Dark" side) with black fonts and borders. Only one side is in play at any given time, starting with the mild side at the start of each new hand. Each side has its own set of four colors, action and Wild cards, and number cards from 1 through 9.

Both sides contain two "Flip" cards in each of their respective colors. Whenever a Flip is played, both the stockpile and the discard pile are immediately turned over and all players must turn their hands around to play the other side of their cards.

The colors for this side are red, blue, yellow, and green. The action cards for this side have lighter effects, and they are as follows:

• Draw One: Next player in turn order draws one card and loses a turn.
• Skip: Next player in turn order loses a turn.
• Reverse: Switches the order of play (clockwise to counterclockwise, and vice versa).
• Wild: Player names the next color to be matched. May be used on any turn.
• Wild Draw Two: Player names the next color to be matched; next player in turn order draws two cards and loses a turn. May only be used if the player has no cards of the current color.
• Flip: Switches all cards from mild to wild side.

The colors for this side are teal, orange, pink, and purple. The action cards for this side have stronger effects, and they are as follows:

• Draw Five: Next player in turn order draws five cards and loses a turn.
• Skip Everyone: Grants an extra turn.
• Reverse: Same as mild side.
• Wild: Same as mild side.
• Wild Draw Color: Player names the next color to be matched; next player in turn order must draw cards until they get one of that color, after which they lose a turn. May only be used if the player has no cards of the current color.
• Flip: Switches all cards from wild to mild side.

A player who fails to call "Uno" after playing their next-to-last card and is caught by another player before the next draw/play must draw two cards as a penalty.

When a Wild Draw Two or Wild Draw Color is played, the next player in sequence may challenge its use if they believe the player who played the card could have played a card of the previous matching color. The challenged player must then show their cards privately. If the challenge is valid, the challenged player must draw the cards, otherwise the challenger must draw them, plus two more as a penalty.

When one player uses their last card, they have "gone out" and the hand is over. That player scores points for all cards held by opponents as follows:

• Number cards: Face value
• Draw One: 10 points
• Draw Five, Reverse, Skip, Flip: 20 points
• Skip Everyone: 30 points
• Wild: 40 points
• Wild Draw Two: 50 points
• Wild Draw Color: 60 points

Points are scored based on the side that is in play after the last card is laid down. If a player goes out by using any card that requires the next player to draw, that player must draw the appropriate number of cards before the scores are tallied.

The first player to score 500 points wins the game.
