In Up or Down?, you build ascending and descending rows of cards, trying to place as many cards of the same color in a row as possible

To set up, shuffle the deck, deal each player a hand of three cards, reveal six cards and place them in a ring from low to high, then split the deck in half and place these piles in the center of the ring, one face up and the other face down. The deck contains cards numbered 1-126, although you adjust the deck based on the number of players.

On a turn, place a card from your hand between the surrounding numbers in the ring, e.g., 37 between 34 and 52, then you take one of the cards surrounding your just-placed card and add it to your display, either starting a new row or adding to an existing row. (If your card is lower than the lowest number or higher than the highest, place it between the lowest and highest card, then add one of those cards to your display.)

You can have up to three rows in your display. When you place a second card in a row, you must decide whether the cards in that row will be placed in ascending order or descending, and you stack the cards accordingly. If you cannot or do not want to place a card in a row — following the ascending or descending order you set up — take all the cards in a row of your choice, flip them face down into a personal discard pile, then start a new row with your current card.

To end your turn, draw a card from either pile inside the ring. Once all the cards in the game have been played, score your rows. For each row, multiply the number of cards in that row by the number of cards in the most common color in that row. For each card in your discard pile, score 1 point. Whoever has the most points wins.
