Crazy Quilt (also known as Indian Carpet and Japanese Rug) is a solitaire card game using two decks of 52 playing cards each. The game is so-called because the reserve resembles the weaves of a carpet or an arrangement of a quilt, with cards alternating vertical and horizontal rotations. The arrangement of the cards on the reserve is also the reason it is rarely seen on computer solitaire packages, most of which have their cards placed vertically.
