Make 13 your lucky number by mastering these tricky card pyramids!
How to Play Pyramid Solitaire Duel
Click two exposed cards that add up to 13 to remove them from the board. You may also use cards from the stack below the pyramid, which contains 24 cards, and can only be flipped through once.
Score points by removing cards. Once you have run out of possible pairs (or have cleared the board), your opponent's time remaining will be reduced to 30 seconds. When the time is up, the player with the higher score wins.
You will receive 13 points for each pair you remove and will earn extra points for removing cards at the tops of the 3 pyramids: for the first card, you'll score 50 points, for the second, 100 points, and for the third, 200 points. The player who finishes first will receive a bonus of 13 points.
