About Pyramid 13 3D
Pyramid 13 3D is the classic pyramid patience card game, and great adding practice. Cards are laid out in a pyramid, each row overlapping the one above. Tap two uncovered cards that add up to 13 to take them away: 8 and 5, 6 and 7, a Jack (11) and a 2, a Queen (12) and an Ace (1). A King is worth 13 all by itself. When you are stuck, turn over a card from the deck; you can go through the deck three times.
There are ten pyramids, from 3 rows up to the full 7-row pyramid of 28 cards. Every deal has been checked by a computer to be winnable, and the Hint button asks the same solver for a good move, while Undo takes moves back. Clear a pyramid without hints for three stars; coins buy new card backs. The Numbers button shows what the picture cards and Aces are worth.
With red-green, red-blue or red-cyan 3D glasses each row of cards sits in front of the row it covers, like real cards on a table; it plays in colour without them. The How 3D works page shares the trick of the six pairs that make 13.
