Pyramid (Classic Card Game)

Pair exposed cards that add up to 13 to remove them from the pyramid, with Kings counting as 13 and removed alone. Select only cards not covered by other cards in the pyramid to make valid pairs. Draw from the stock to the waste and pair the top waste card with an exposed pyramid card to make 13. Use undo to rethink moves and hints when you get stuck to reveal potential pairs. Plan ahead to free blocked cards and manage the stock to create chains of removals. Clear all cards from the pyramid to win; if no pairs remain and the stock is spent, the round ends.
