In this trick-taking game based on the short story by Robert Louis Stevenson of the same name, the goal is to gain the most points over a series of hands (usually the goal is set to 200 pts). Cards are numbered 1-37 and are found in three colors, red (comprising largely the highest numbers), blue (mostly in the middle) and yellow (mostly the lowest numbers) with colors being analogous to the suit in a standard deck. There is one neutral card, the 19, that sets the "price of the bottle."
