This game uses a 7-column single-suit spade spider solitaire deck, with simple and easy-to-understand core rules. Cards must be arranged in descending order: K→Q→J→10→2→A. Collecting a complete chain of 13 cards will automatically eliminate the remaining cards. Clearing all cards on the table will complete the game.
Adjacent cards can be stacked, and consecutive descending chains can be moved as a whole. After clearing a column, cards can be placed freely. Removing a face-up card from a column will automatically reveal the bottom face-down card; unlocking the face-down card first will make it easier to complete the game.
