If you have a 9 in your hand, you may play it to capture a 2, 3, and 4 on the table.
If they do, play the card from your hand to capture the cards with the same total value on the table, and add them to your face-down scoring pile. Check if the combined value of any cards on the table adds up to the value of one of the cards in your hand. Capture multiple cards by playing a card matching their total value.
