Score 5

The title Score 5 indicates what you do at game's end: Score five cards, specifically the highest card of each color in your hand.

To start, each player has the same five cards - 5, 10, 15, 20, 25 - in one of the five colors. Each round, reveal one card from the deck; cards come in one of the five colors or gray (a joker that can be any color), as well as a value higher than 25.

Each player chooses one or more cards from hand to bid on this revealed card. Whoever bids the most wins this card and adds it to their hand, and the cards with which they placed the bid are redistributed among the other players, with players choosing one card from this bid to add to their hand in order from second-highest bid to lowest. (Numbers on the initial cards serve as tie-breakers, when needed.)

After a certain number of rounds, players sum the highest card of each color in their hand, and whoever has the highest total wins.
