Big Turkish Carpet is a matching game: remove equal ranks from the exposed ends of ten columns. There are 80 tableau cards and a 24-card stock.
Unroll the carpet
Drag one available card onto another of the same rank; both disappear. Colors and suits are irrelevant. Cards beneath them become available, but unmatched cards cannot be moved into new columns. Draw one stock card when you need another partner, and recycle the waste without a pass limit.
With two decks, several copies of one rank may be exposed at once. Pair the cards whose removal opens the most useful columns. If a waste card matches, consider using it first to reveal the card beneath it. The goal is an empty tableau, not an empty stock.
