Pyramid
Pyramid solitaire: pair cards that add up to 13.
Find pairs that add up to thirteen in Pyramid card games on PuzzleGamesOnline.io. Remove available cards from the pyramid-shaped layout and uncover those beneath them. In standard rules, kings can be cleared individually, while other ranks need a matching partner to reach the required total.
The main challenge is gaining access to the cards you need. A visible pair might be easy to remove, but another pairing could open a more useful section of the layout. Consider the covered cards and the remaining stock as you choose. Each cleared pair brings you closer to dismantling the pyramid.
