The aim of High Seas Solitaire is to remove the cards by grouping them in pairs of the same value, or in pairs that add up to 14.
The cards are randomly-dealt and you must choose two with the same number (eg 6 and 6), or two that add up to 14 (like 9 and 5). Then, use the left button of your mouse to drag one of the cards on top of the other, and they will both disappear. Continue pairing the cards until you clear the entire screen – and then dive into the next screen.
