Nautches is a deck of 120 hexagonal cards, used to play a number of abstract games ranging from two-player territory-building games, to multiplayer trick-based games, to meditative solitaire games. Each side of a Nautches card is marked with notches indicating a value between 0 and 5. Each of the 120 cards has a unique sequence of notches. Each card also has one of six suits and one of two colors. Most games are based on placing such that the notches on any touching sides of cards have matching values.
