Button Shy Games hosts monthly challenges to design 18-card games. This month's challenge was to use 18 cards from a standard playing deck.
Playing cards don't offer much of a story to base a game on, but I latched on to the idea of the face card royalty. My game is Marry Up, a quick drafting game for 3 players where you're a matchmaker trying to form marriages and marry off your aces to the royal family.
