Tutorial
The goal of Pyramid 13 is to remove all 28 cards from the card pyramid by matching pairs of cards.
The sum of the ranks of a card pair must equal 13.
Aces have a value of 1. Jacks, Queens, and Kings have values of 11, 12, and 13 respectively.
Since a King has a value of 13 points, it may be removed without pairing it with another card.
A card in the pyramid can only be moved if it's completely uncovered.
You may draw cards from the stockpile to pair with pyramid cards.
Once the stockpile is exhausted, you'll be allowed a redeal.
Only a limited number of redeals are allowed, however.
You may also take cards directly from the card reserve.
If you get stuck, you may undo your last move, get a hint, or restart the game
from the beginning by using the menu at the bottom.
The game ends when you either successfully clear the pyramid or when you can no longer perform any valid card matches.
