Penguin Party
In Penguin Party, players collectively build a pyramid of penguins, trying to empty their hands of cards along the way. The deck consists of 36 penguin cards: 8 green and 7 each of red, blue, yellow, and purple. Deal the deck out as evenly as possible, with the final card in a five-player game starting as the first card in the base of the pyramid.
On a turn, you either play a card to the left or right of the base of the pyramid, which can be at most eight cards wide, or play a card on a higher level of the pyramid so long as it's supported by two penguins, at least one of which is the same color as the card being played. If you cannot play a card, discard your hand face down and take as many penalty markers as the number of cards you didn't play. If you empty your hand, you can return two penalty markers previously collected to the supply.
Play as many rounds as the number of players, with each player starting one of the rounds. Whoever has the fewest penalty markers at the end of the game wins. (With two players, deal each player 14 cards, remove the other cards from play without looking at them, and build a pyramid with a base only seven cards wide.)
